Public and Private Gardens in the Eighteenth Century

By Chelsea Clark

Sloane was unique in his collecting habits and connections to gardens. He was passionate about obtaining plant specimens and discovering their various medical uses, however, appeared to be less interested in being personally involved in gardening. This is apparent when comparing his practices to those of his friend and colleague, Richard Richardson.

Despite the growing popularity of private gardens in England, Sloane did not have a garden of his own. His method of collecting botanical specimens was to dry them and press them in books, or keep them as seeds. Many of his letter correspondents cultivated gardens of their own and experimented with acclimatizing foreign specimens to English soil. Why did Sloane assist the Chelsea Garden at its time of crisis (mentioned in first post) if he was not trying to gain access to a garden of live specimens? How did his apparent abstinence from gardening connect with his support of the Chelsea Garden for the advancement of pubic botanical knowledge?

Sloane valued the plant knowledge that could be obtained from the garden knowing that it would indirectly aid him in his own pursuits as well as the greater scientific community. The published catalogue of the first transfer of fifty specimens (Philosophical Transactions, 1722) stated that Sloane’s motivation was to “encourage and promote an Undertaking so serviceable to the Publick.”

Curiously, there were no records of letter communication from Phillip Miller, the botanist placed in charge of the Chelsea Garden, to Sloane in regards to the Chelsea Garden. It seems most likely that the lack of correspondence reflects Sloane’s close proximity to the garden and opportunities to see Miller in person. (Though, arguably, it might also suggest that Sloane was disconnected from the garden.)

Richard Richardson, maintained a garden of his own at his home in North Bierley. His private garden earned a reputation as the best in North England and housed both native and foreign plants, including a hot house for growing exotic fruits. Richardson collected for his garden himself on explorations as well as obtained specimens through his associations with other private and public gardens. From his letters to Sloane, Richardson appears passionate about exotic specimens, whether it was acclimatizing them to English conditions or fabricating greenhouses to mimic their native growing conditions. This was a much different approach to specimens than Sloane’s.

Richardson mentioned his garden in North Bierley several times to Sloane. It contained botanicals that even the Apothecaries’ Chelsea Physic Garden lacked. Richardson obtained plants for his personal garden from public gardens, such as the Edinburgh Physic Garden. This exchange of plants between private and professional gardens is an interesting feature of English gardens.

These private collectors were also part of an exchange network with Dutch and French professional gardens. One reason was that the men who were collecting, like Richardson, had the wealth and leisure to maintain a garden and were associated with scientific societies like the Royal Society of London. Their collection of botanicals was not just for aesthetic reasons or to display their status, but their scientific functions gave collectors the authority and expertise to trade with the professional gardens of physicians and apothecaries.

In a letter to Sloane dated 13 November 1725, Richardson mentioned an “unfortunate accident” that occurred to some “scotch plants” from the Physic Garden at Edinburgh which he “proposed to have brought back … for my garden.” In addition to collecting from other gardens to fill his own, Richardson mentioned also wanting to make his collecting habits useful to others by collecting plants from northern England for the Chelsea Physic Garden and Mr. Miller. Unfortunately, he ran into some difficulties in creating such a relationship with Miller. On 8 April 1727, Richardson wrote about exchanging mosses with Miller for some seeds. On 19 November 1728, Richardson mentioned receiving a list of desired plants from Miller and had been collecting what was still in season from his garden to send to Chelsea.

Richardson’s attempt at a reciprocal relationship of exchange from his garden to the Chelsea public garden soon fell apart. By 16 March 1729, Richardson had stopped receiving letters from Miller. Even after a visit to Chelsea in the summer, during which Miller promised he would send Richardson a letter detailing which plants the garden was lacking, Richardson wrote to Sloane on 3 November 1729 that he had not received a letter of this sort. For some reason, unknown to Richardson, their amicable exchange ceased. (For more on relationship etiquette see this post regarding Abbe Bignon and Sloane).

Richardson sought out associations with other gardens, and he demonstrated great attachment to and took great care with his own garden. It is likely that Sloane received dried plant specimens or seeds from Richardson’s personal garden that had originally come from Miller at the Chelsea Garden, given that he was recieving other dried specimens from Richardson. Other than that, Sloane’s involvement in the Chelsea garden appears to have been kept separate from his desire to collect and classify, stemming instead from his desire to expand the public’s botanical knowledge and to ensure supplies of medical specimens.


On Tooth Worms

St. Apollonia, patron saint of tooth pain. Francisco de Zurbaran, 1636.

The 9th of February is St. Apollonia’s Day and, in the U.S., National Toothache Day. So I offer you tooth-worms, which–as Nicolas Andry described them in An account of the breeding of worms in human bodies (1701)—“occasion a deaf Pain mix’d with an itching in the teeth; they insensibly consume the Teeth, and cause a hideous Stink” (85). On 3 July 1700, John Chamberlayne wrote to Hans Sloane on the matter of his own tooth worms.

Now, these men were not people with particularly weird ideas, even for the time. Rather, the idea that toothaches were caused by worms had been around for a very long time. For a good overview of this verminous history, you should read Lindsey Fitzharris’ post on “The Battle of the Tooth Worm”.

This idea was still widely held in the late seventeenth century, even by the intellectual elite. For example, at a Royal Society meeting on 18 July 1678, Robert Hooke compared a growth within a tree trunk to tooth rot. At this point, Society members digressed into discussions of worms causing rot and the removal of tooth worms. In one case, a woman extracted the worms with a sharpened quill; in other cases, “the same thing was done by the help of the fumes of henbane seeds taken into the mouth; whereby the saliva falling into a basin of water held underneath, would discover several living worms, supposed to issue either from the gums or teeth”.[1]

Old knowledge could even, seemingly, be supported by investigations using new technologies. In a letter published in the Philosophical Transactions of the Royal Society in 1684, Anton van Leewenhoek described his microscopical observations “about Animals in the Scurf of the Teeth”. Leeuwenhoek started with his own teeth, “kept usually clean”. He examined other samples of tooth plaque from two women, an eight-year old and two old men.Using his microscope, he discovered several sorts of creatures, some like worms, in the plaque—so many that “they exceed the number of Men in a kingdom”. These creatures, though, were present in sound, healthy teeth. Could these be tooth worms?

Leeuwenhoek was not so convinced by 1700 when two of his letters “concerning Worms Pretended to be Taken from the Teeth” was published in the Phil. Trans. He had examined two worms “taken out of a corrupt Tooth by smoaking”, one of which was still alive after four days in the post (sent on 4 July 1700). Leeuwenhoek believed it came from the egg of a type of fly that laid their eggs in cheese. He rounded up more worms from his local friendly cheesemonger and ran several experiments (including watching the worms copulate).

As to how the worms ended up in the teeth… Teeth—or, flesh more specifically—were not the worms’ natural habitat. The flies took nine days to mature, but meat needed to be salted or smoked sooner. Leeuwenhoek instead believed that the worm specimens had come from a patient who

had some time before eaten Cheese laden with young Worms, or Eggs of the above-mention’d Flies, and that these Worms or Eggs were not touch’d or injur’d in the chewing of the Cheese, but stuck in the hollow Teeth.

Gnawing worms had caused the tooth pain. Or did they?

For his work on bodily worms, Andry had also examined some worms “that a Tooth-Drawer took off of a Lady’s Teeth in cleaning them”. Based on this case, Andry concluded that tooth worms rotted the teeth, but did not cause any pain. These small, long and slender worms with round black heads bred “under a Crust that covers the Surface of the Teeth when they’re disorder’d” (38).

To the modern reader, Leeuwenhoek’s argument is more sensible. Sure, there might be microscopic creatures living on the teeth, but they were not the same as the so-called tooth worms… which were really more cheese worms than anything. But at the time, Andry’s version would have been compelling. Worms were thought to breed in unclean conditions and, as Andry made clear, they could breed under a crust on an unhealthy tooth: it was the disorder in the tooth, not the worm, that caused the pain.

When John Chamberlayne, Fellow of the Royal Society, wrote to Sloane about his own tooth-worms, he did so in the interest of advancing knowledge and reporting on an efficacious treatment. He did not ask for Sloane’s advice, but instead reported on his visit to Mr. Upton, known for his “tooth-candling” expertise. Using heat and smoke, Upton removed rheum from Chamberlayne’s gums and extracted ten or twelve worms. This was apparently on the low side, since Upton on a really good day could remove sixty worms.

Chamberlayne claimed that he ordinarily had no faith in men such as Upton (meaning: irregular practitioners, sometimes known as quacks), but many gentlemen of his acquaintance had attested to the success of Upton’s treatment. Of course, given that Chamberlayne also described his teeth as “loose and corrupted”, he may also have been willing to try anything for what must have been terrible pain!

Chamberlayne was familiar with the wider discussions about bodily worms, referring, for example, to Leeuwenhoek’s 1684 article in the Phil. Trans. Besides the report, Chamberlayne may have taken a chance to do his bit for knowledge in another way: he may have sent Sloane some tooth worms. Is it just coincidence that Chamberlayne’s letter to Sloane was dated 3 July 1700 and that Leeuwenhoek referred to worm specimens sent on 4 July 1700?

Whatever the case, one moral of the story is: choose your cheese wisely if you have bad teeth.

A Most Dangerous Rivalry

By James Hawkes

The Royal Society is in turmoil as competing factions battle for control. Not only is our hero Hans Sloane’s job on the line, but the very existence of the Royal Society hangs in the balance…

No this is not the TV Guide summary of a niche costume drama, but the results of a bitter dispute between Dr. Hans Sloane and Dr. John Woodward in 1710. Not only did these men have starkly different visions for the future of the Royal Society, but they were competitors for rare curiosities and specimens. It’s perhaps not surprising that the men became rivals! Woodward launched a concerted campaign to unseat Sloane, which nearly succeeded.

Woodward, professor of Physic at Gresham College, championed a highly empirical and experimental approach for the Royal Society. He resented Sloane’s tendency to publish an increasingly ‘miscellaneous’ assortment of articles in  the Royal Society’s Philosophical Transactions–particularly those written by Sloane’s friends. (This was, admittedly, a complaint even by men who liked Sloane!) Woodward naturally considered the man most disadvantaged by this unjust state of affairs to be himself.  He made it his mission to save the Royal Society from those he feared would undermine the scientific progress of mankind.

Sloane and Woodward actually had much in common: they were both medical doctors with a deep-seated curiosity about the natural world. They were also active in the Royal Society and the Royal College of Physicians. Both earned considerable respect for their scholarly endeavours: Sloane, for his botanical work on the West Indies, and Woodward, for his prolific writings, especially on geology. Each man had a circle of scientific contacts across the British Empire and the Continent.

Sloane and Woodward also built impressive collections of natural and antiquarian items, preserved for posterity by (respectively) the British Museum and the Woodward Professorship at Cambridge. Woodward is even on record in a letter to Sloane declaring that he thought himself Sloane’s friend… albeit in the context of trying to explain away intemperate remarks about Sloane.

But the Devil is always in the details. Sloane had a reputation for collecting pretty much anything that fell into his hands. Woodward, however, focused on what he thought to be academically useful. These different approaches helped Woodward to drive a  wedge between Sloane and Sir Isaac Newton (then President of the Royal Society), who had little respect for Sloane’s collecting habits.

The situation finally exploded in 1709 when Sloane, as First Secretary of the Royal Society,  published a book review by Woodward’s long-standing enemy Edward Lhwyd. In his review of the work of a Swiss geologist, Lhwyd went out of his way to ridicule Woodward’s theories. Woodward demanded satisfaction. One contemporary said he did not know if the affair would end

whether by the sword or by the pen. If the former, Dr. Mead has promised to be Dr. Sloane’s second.(Levine)

Dr. Mead was, of course, another one of the many enemies that Woodward was so good at making. Indeed, ten years later Mead and Woodward duelled to resolve a dispute on the best way to treat smallpox. There are many versions of what happened. According to one, with Woodward defeated Mead bellowed, “Take your life,” to which Woodward replied, “Anything but your Physic.” But that is another story.

In an attempt to keep the bickering between Woodward and Sloane from escalating into violence, Sir Isaac Newton forced Sloane to publish a retraction, indicating he thought some of Woodward’s ire was justified. Woodward’s plans to overthrow Sloane nonetheless continued apace. Woodward managed to get a friend, John Harris, elected secretary. He then proclaimed in a letter to Ralph Thoresby that:

Dr. Sloane declared at the next Meeting he would lay down…. He guesses right enough that the next step would be to set him aside.

Woodward and his faction were so confident by this point that he criticised Newton as incapable. Harris even invited Newton’s nemesis, Leibniz, to write for the Transactions. Perhaps Woodward’s ambition was becoming so great that he hoped to be Newton’s successor as President of the Royal Society–an honour that would fall to Sloane much later, in 1727.

The power struggle culminated when Sloane was presenting on bezoars to the Society. Woodward attacked Sloane’s thesis and Sloane, unable to come up with a reply, allegedly resorted to making faces at Woodward.  These grimaces were “very strange and surprising, and such as were enough to provide any ingenuous sensible man to a warmth.”

The Council was convened to resolve this controversy once and for all. They debated whether Sloane had actually been making faces and whether Woodward’s ire was justified. Woodward seemed on the brink of victory, but then lost his temper when Sloane denied the charges: “Speak sense, or English, and we shall understand you!” Woodward, unwilling to apologize was summarily kicked out. He then claimed that Sloane had packed the Council with his cronies, complaining to no avail of the “Mystery of Iniquity that reigns there.His friend Harris was soon enough replaced and so his entire revolution fell apart.

Although it may be more amusing to think of these eminent doctors as perpetually busy with childish bickering, they were capable of acting professionally on occasion. Even after this great controversy Woodward was willing to recommend  Sloane to a patient and attempted to enlist Sloane’s support to obtain a lucrative new position. Still, their showdown does appear to have put a bit of a damper on their correspondence, and it would seem that their relationship never entirely recovered.

As it happened, with Woodward gone, Sloane and Newton soon fell to sniping at one another. When Sloane was forced to resign as secretary in 1713, Woodward ended up on the side of Sloane against Newton, who Woodward now saw as an evil tyrant holding the Society back.

The more things change, the more they stay the same?

Storms, Sounds and Authorship

The wind has been wildly whipping the last few days, putting me on edge. It doesn’t help that the wind makes the neighbourhood noisier than usual: clanking gates, blowing cans… The normally distant rumble of the tube train suddenly passes right down our street, while the planes seem to fly right over our roof. The weather can do funny things to sound.

Back in 1708, William Derham was inspired by his observations on weather and sound to publish on the motion of sound in the Philosophical Transactions. Derham’s letters to Sloane show how Derham had carefully thought about the subject for years before his article appeared. Academic writers will have much sympathy for Derham’s path toward publication.

In January 1704/5, Derham was confident that he was “setteling the business of the Flight of Sounds, which may be of good use”. He had ten questions and was happy to add more if anyone in the Royal Society had any; by the time he published, there were nineteen questions. Derham was charting the sound of gunfire to determine what factors affected sound, such as the type of winds and weather, size of gun, time of day, and direction of the shot.

Many credible authorities, from the Florentine Academy to Isaac Newton, had differed on the question of “What Space Sounds fly in a Second or any determinate Time?” To settle the matter, Derham repeated their experiments and at greater distances. The answer seemed close:

I have allmost satisfied my self about all the former Enquiries, which when I have fully done I will impart it to the Society. I only want a few Guns from the Tower or some such large distance (which I could see in the Evening) to fully confirm what I have already done.

Derham was more guarded by April 1705. He reported that he was not as close to finishing his experiments as he’d hoped. Having met “with fresh matters” that nobody had ever observed before, he was “cautious of determining any thing precipitatly; & therefore I shall yet delay giving the Society an account of what I have done”.

What he could tell them was that “Storms do accelerate Sounds, wch I did not discover (only suspect) till last Fryday” when he had been timing the sound of guns fired at Blackheath. Contrary winds resulted in delays, while high winds sped the sounds up. But to test his theory, he needed more guns. Derham reassured Sloane that he would “use my greatest care in all this matter” because his newest observations differed so greatly from those of others–and “perhaps the Societys reputation my be somewhat hurt by any neglect or want of an act”.

In December 1706, Derham was still working on the project. He had only just found “an excellent semi-circle to take the Angles, & thereby the distances of the places from whence I observed the Flight of Sounds”. This, he noted, “was the only thing that hath delayed the me from imparting my Observations on that subject.” And in April 1707, he referred in passing to using triangulation to measure sound.

Finally, Derham sent off his observations in February 1707/8. His letter hints at his relief, as well as his hope that the article would be published as soon as possible.

I have sent you my Observations about Sounds; which as it hath cost me some pains, so I hope will be acceptable to you, & the most illustrious Society. If you think it worth publishing in the Transactions, I desire you will be pleased to put it into one of the next.

A week later, Derham’s anxiety emerges more clearly when he wondered whether Sloane had even received the article: “Be pleased to let me know whether you recd my account of Sounds with my Packet of Lrs from Florence.”

The article was intended to be Derham’s Important Work (and it was), appearing as it did in Latin rather than the English he usually used for his Phil. Trans. submissions. It also took up a full thirty-three pages. With his careful measurements, increased distances, and use of instruments, Derham provided a more accurate assessment of the speed of sound than previous scholars.

It’s just a shame that Derham never mentioned his mysterious Japanese (?) co-author anywhere in his letters to Sloane…

According to a data entry howler error in the online Phil. Trans., Soni Motu was the first author on the article. How’s that for revisioning history?

The Twelve Days of Christmas

Inspired by the season, I started playing with my database of Hans Sloane’s correspondence to see how many items from The Twelve Days of Christmas to my wondering eyes should appear. Although some substitutions were required, all twelve days are represented—and, in turn, hint at the breadth of Sloane’s collections, medical practice and epistolary network.

On the first day of Christmas, my true love gave to me… an account of the King hunting partridge from 8 in the morning until four in the afternoon in August 1724. It is unspecified whether any partridge was also in a pear tree. In a stunning twist for the song, George was also hunting rabbits and the trip had to be cut short because of a storm. Safety—and partridges—first, everyone. In any case, the King and his party were very tired after such a long day.

For the second day of Christmas, I found no turtle doves, but there are pigeons. And they are just as good, maybe even better, since I’ve never heard of anyone eating dove. Thomas Hearne, in an undated letter, reported that he was coughing up blood and receiving medical help from the Duchess of Bedford. All he was able to eat was milk and pigeon. Not my usual choice of dinner, but to each one’s own.

For the third day of Christmas, I was unable to locate any foreign hens. There was, however, an odd pheasant hen sent by John Hadley in 1721. He thought that Sloane might enjoy dissecting the hen because her feathers had changed several years previously from the usual hen colours to that of a cockerel.

I hoped to find collie birds (blackbirds) or calling birds (song birds) for the fourth day of Christmas—and I found several of each in one letter! In 1721, Richard Richardson sent Sloane the eggs and nests of several types of birds, including larks, thrushes, crows and blackbirds. Thank you, Mr. Richardson for being so obliging.

But what about five gold rings? I happily settled for one with a fancy, though indecipherable, inscription from Charles Preston in 1699. One ring to rule them all?

The geese, laying or otherwise, posed the greatest trouble. Goose does come up in the database, but only as a description. Mark Catesby in 1724 compared another bird specimen to a goose in size and Emelyn Tanner in 1727 described a deformed baby as having down like a goose.

The only swans mentioned in the letters are pubs, though the drinkers may or may not have been swimming in their drink. For example, Richard Richardson (1729) referred to a carrier from Preston who would be staying at the Swan in Lad Lane, London. Or Antony Picenini stayed at the Swan Tavern in Chelsea, hoping that a change of air would benefit him while he recovered from (unspecified) surgery on his thigh.

There were some maids mentioned in relation to milk, but only one maid doing any milking—in this case, drinking milk rather than fetching it. In 1725, Matthew Combe was treating Sophia Howe, Maid of Honour to Queen Caroline, for a bad cough. The patient had been drinking asses’ milk, commonly given to people suffering from chest troubles.

Although there were no drummers drumming, there is at least a drum. In 1729, Elizabeth Standish of Peterborough was planning to send Sloane “a Negro drum”. No other details were given, such as where the drum came from or how Mrs Standish had acquired it. Could this be the same Akan drum still held at the British Museum?

There is only one reference to a piper actually piping. In 1723, Timothy Lovett reported that he had been treating his long-standing phlegmatic cough (forty years) by smoking a pipe: “I have used my selfe to smoking several years about 5 pipes a day but it is ready to make me short breathed. I find it opens and loosens ye body.” Smoking as a cure… it worked until it didn’t, apparently.

Now, the Lords and Ladies were apparently too dignified to mention their leaps and dances to Sloane, but the subject of their exercise does occasionally come up. I offer you one Lord, the Earl of Derby, and one Lady, Lady Clapham. Derby suffered from swelling and bad breathing in 1702. He was “most pusled what to do about exercise, which is so necessary, but the least causes my legs to swell so”. Lady Clapham was also ill in 1702 and her regular physician despaired of the elderly woman’s skin disorder, hard swellings all over her body. He wasn’t sure if “the cause of this disease may proceed from a great stomach & little exercise or a great surfeit of cherries in London”. Tough one…

Since I clumped Lords and Ladies together, I’ll end with an 1842 version of Twelve Days which has twelve bells ringing.  After Sloane was elected President of the Royal Society in 1727, the bell-ringers of St. Giles-in-the-Fields honoured him by ringing the bells. St. Giles only has eight bells today and, in 1727, would only have had four bells. But no matter, it’s the thought that counts and a four-bell honour is pretty darned fine!

And on that (ahem) note, I wish a Merry Christmas to all.

Strange Pigs

There are strange pig tails in the midnight sun
From men who moil for hog’s stones
The science trails have their secret tales
That would make monstrous piglets groan;
The English nights have seen queer sights
But the queerest they ever did see
Was that marge on the note of Stephen Gray
Concerned with porcine impersonation.(1)

Pig tales occasionally show up in the Sloane Correspondence, and they are inevitably crackling good fun. But what do pigs have to do with the history of science? A while back, Samantha Sandassie (@medhistorian) wrote a fascinating post on the role of pigs in early modern medical history: besides providing a useful addition to one’s diet, pigs were often the subject of wondrous stories. By the eighteenth century, they were also the subject of Royal Society interests: classifying strange objects from animal bodies, understanding the development of fetal deformities, and analysing the composition of food stuffs.

John Morton, a naturalist who described fossils and wrote The Natural History of Northamptonshire, wrote to Hans Sloane about an extraordinary hog’s stone in April 1703. Morton thanked Sloane for his friendship and promised his service in return; this included sharing his work in progress on fossils. The description of the hog’s stone was, presumably, a taster for Sloane, but Morton also mentioned the possibility of sending it as a gift to the Royal Society. Sloane’s patronage was desirable, but even more so was attracting the interest of the Royal Society, and Morton was successful in both.

On the 30th of November 1703, Morton—nominated by Sloane’s rival, John Woodward—was accepted as a Fellow of the Royal Society. By June 1704, Morton had gifted the stone to the Royal Society after they had favourably received his account of it. A seemingly small offering, perhaps, but one that helped to establish a correspondence that continued for over a decade.

Sloane’s family members also sent him objects of interest. On Sloane’s birthday in 1711, his stepson-in-law John Fuller sent “a Couple of Monstrous Piggs, one of them was farrowed alive the other dead, the sow had six Piggs beside, all of them as they should be”. A quick perusal of the Philosophical Transactions of the Royal Society reveals that monsters remained a source of fascination to the Society throughout the eighteenth century.

Disability and deformity were frequently explained in terms of the influence of maternal imagination: that the pregnant woman either had cravings or had been subjected to extreme emotions, either of which could shape an unborn child. (See, for example, Philip Wilson’s article on maternal imagination and disability.) Fuller’s piglets would have been especially intriguing, given that only two of the sow’s litter had been monstrous. What might the study of deformity in animals mean for the medical understanding of human reproduction? And why, moreover, were traits only passed on to some offspring? Food for thought: a fine gift, indeed, for Sloane!

But the strangest pig tale in the correspondence is from Stephen Gray, who was better known for his work on electricity than porcine expertise. Even so, in the summer of 1700, Sloane requested that Gray send further details about the fat of some pork that he had sent to the Royal Society. Gray denied all knowledge of the pork sample, insisting that either someone had the same name or was impersonating him. A fairly random occurrence that raises so many tantalizing questions: was there another Stephen Gray who was a pork expert? Was this a practical joke? And if so, was it intended for the Society or Gray? And what was its point? In any case, the Society clearly wanted to find out more about the chemical composition of pigs.

These three little pig gifts may seem like small tokens, but reflect the roles of patronage, reputation and curiosity in early eighteenth-century medical and scientific knowledge. Now, if only the joke or insult behind Gray’s impersonation could be deciphered: any thoughts?

The Preserved Puppy Proposal

Edmund Curll, a bookseller’s apprentice, wrote to Sloane in 1703 with news of “A Wonderfull production in Nature”: an unusual puppy.

Recently, a Scottish gentleman’s dog had

Whelp’d two Puppies one of them was whelp’d dead and the other that was whelp’d alive being a Male in 24 hours after voided from the fundament another Little Creature wch Liv’d 10 Hours and is now preserv’d in Spirits of Wine.

This, Curll promised Sloane, could “be produced Sr if you please to give yourself the trouble”.

By 1703, Sloane was already known for his collection of curiosities, but it was in Sloane’s capacity was secretary of the Royal Society that Curll approached him (as the letter’s address specified). Presumably Curll thought that Sloane, in particular, would be unable to resist a strange “Little Creature” born from its mother’s anus.

Dogs, of course, were often used in experimentation, so an unusual specimen may well have been of interest to the Royal Society—though I would have been more curious to examine the mother to determine whether the anal birth had resulted from a congenital problem or an injury caused by the whelping.*

In writing to Sloane, perhaps Curll was hoping to strike up a common interest with a potential patron who was known for buying books as well as oddities—or, maybe, he was just hoping to turn a quick profit on a dead puppy.

Capitalizing on (bad) luck and death was certainly one of Curll’s overall career-building tactics. In 1708, he took over his master’s bookselling after Roger Smith went bankrupt. And his career went from high to high (or low to low), as Curll became infamous as a seller of dodgy remedies to treat venereal problems and a purveyor of cheap dirty books and scandals. He was also known for publishing scurrilous and unverified biographies of recently deceased people, leading physician John Arbuthnot to (allegedly) comment that Curll was “one of the new terrors of death”.

Was it a coincidence that Curll can be spotted trying to sell Sloane a preserved puppy so early in his bookselling life? Or was the puppy a harbinger of Curll’s future approach to his career?

* My internet search history is now filled with some pretty iffy search terms and I’m no wiser, although I suspect an injury. I also discovered that there are a lot of preserved puppies available for sale on ebay and etsy, but no relevant historical pictures of such specimens.

Sir Hans Sloane, Abbé Bignon and Mrs. Hickie’s Pigeons

In 1720, Dr. Den. Hickie complained to Sloane about an ongoing dispute with a neighbour:

the Lord of the Manor who is intent upon me as a stranger to do me prejudice & particularly in destroying a few pigeons that my wife has always kept without molestation since first shee bought her estate in this Countrey.

The country in this case referred to France, not just the countryside. Dr and Mrs Hickie had moved to Meulan sur Seine from London. It was “the profes that you have given me of your friendship whilest I resided & practiced in London”, Hickie wrote, that “encourages me to take the liberty of importuning you at present”. Hickie reminded Sloane that the friendship had not been one way, as he had been sending his observations to the Royal Society on Sloane’s directions.

Sloane might not seem the obvious choice to assist with a neighbourly dispute in France, until Hickie specified who is neighbour was: one of the Abbé Bignon’s brothers. By 1720, Sloane and the Abbé had been regular correspondents for over twenty-five years (which Ann-Marie Hansen discusses in another post). Although Hickie had met the Abbé in person and been received upon Sloane’s “acc[oun]t wth a great deal of civility & friendship”, he clearly was not in a position to ask the Abbé directly for assistance. But he hoped that Sloane would intercede with the Abbé on his behalf:

a word speakeing from the Abbé at his Brother is enough to free me from the disturbance that this man designes to give me therefore I hope that you’ld contribute to protect me by your recommendation.

This is a letter that highlights the complicated routes that patronage might take. One could not just approach someone of the Abbé’s standing on a limited acquaintance, especially in France where the rules of patronage were even more stringent than in England. An intermediary was crucial. And who better than the one who had introduced Hickie to the Abbé in the first place?

But… it’s really the dispute over pigeons in this letter that captures my interest.

Pigeons were not just valuable livestock, but one that owners (or “fanciers” as they even called themselves in the 1700s) seemed to hold in great affection. The most common use of pigeons was for food, which provided a steady supply of meat year round. In his Columbarium: or, the pigeon-house (London, 1735),

John Moore argued that pigeon dung was particularly important for fertilizing crops, making medicines, tanning leather and producing salt-petre. The dung was so good that it “challengeth the Priority, not only of the Dung of Fowls, but of all other Creatures whatsoever, on the accont of its usefulness in human Life.” Moore’s chapter on treating pigeon distempers suggests the lengths that fanciers might go to care for their pigeons: special diets, imported ingredients (such as tobacco) and attentive nursing. The attack on Mrs Hickie’s pigeons must have been upsetting for the Hickies on several levels.

Alhough Hickie suggested that Bignon was attacking the pigeons because the Hickies were not local (a natural fear for anyone living in a foreign land), the reasons are likely far more complicated. Whereas there were no regulations on who might own pigeons in eighteenth-century England, French law was very clear–only lords of the manor had the right to keep or kill pigeons. This feudal right was considered to be such a fundamental mark of inequality that it was revoked in the second article of the 4 August Decrees of 1789, which were passed by the National Assembly to settle peasant unrest in the countryside during the French Revolution.

It’s unclear which brother Hickie meant, but all three brothers were firmly entrenched in the aristocracy: Louis was the Major General of the King’s Armies, Jérôme III was the Intendant of Amiens and Armand Roland was the Intendant of Paris. Such men would not have looked kindly upon mere commoners, however well-to-do, keeping pigeons.

Hickie may have been astute enough to spot the need for an intermediary in the dispute, but he had made a classic ex-pat mistake of fundamentally missing an important cultural difference. What would have been a simple matter of bad neighbourliness in England was at the heart of aristocratic privilege in France.

An early eighteenth-century ghost

By Felicity Roberts

One of the most entertaining set of letters in Sir Hans Sloane’s correspondence was written by William Derham (1657-1735), the rector at Upminster in Essex and an enthusiastic member of the Royal Society.  Derham’s letters to him are so lively that you get a good impression of their shared business and scientific interests–including, it seems, ghosts.

Sloane and Derham began to correspond around 1698 and continued until shortly before Derham’s death in 1735.  Since Derham’s clerical duties frequently prevented him from attending Royal Society meetings, Derham sent his natural history observations to Sloane to be read at Society meetings (Lisa Smith has discussed Derham’s activities in not one but two previous posts). This is especially true for the period during which Sloane was Secretary of the Society, between 1693 and 1713.  Derham wrote to Sloane with observations of the weather; details of his experiments on the speed of sound; and astronomical observations.

Perhaps the living of Upminster did not pay well, or perhaps Derham was just happy to do his friend a favour, but in 1705 it appears that alongside his clerical duties Derham also agreed to be an agent for Sloane in the purchase and management of a farm in a village Derham calls “Orset” (present-day Orsett, south east of Upminster).

The details of the property management letters are fascinating, not only because it shows the social and business connections forged between members of the Royal Society, but also because it suggests how Sloane increased his estate by investing in land.  Exactly how Sloane financed his museum is still not known–his medical practice, sugar plantation, hot chocolate recipe, eye remedy, and property buying must all have contributed.

But my favourite Derham letter is that of 13 December 1708. Derham wrote excitedly to Sloane with an “odd story” concerning Sloane’s farm tenants who:

[R]eceive disturbances constantly every night by great rumbling in the chambers, dashing the Doors open, & shutting them wth [damaged], that the woman’s Spinning-wheel (standing by her [bed]-side in the room they ly) is whirled about as if they spun, yt the warming-pan hanging by her bed-side is rattled & rung, that a woman who lay in one of the Chambres lately had the clothes pulled off her bed perpetually, & putting out her hand to pull them on, she felt a cold hand take her by her hand.

Derham’s story, which he has had second-hand from a neighbour, is rather breathlessly related.  And indeed, the details of the spinning-wheel operating of its own accord, and of the bed clothes being pulled off by a cold hand during the night, are pretty spooky.  But it seems that Derham’s curiosity has been aroused rather than his fear.  He encouraged Sloane:

 “You being a curious man, I wish you would come, & we would go, & ly there a night.”

True to their Royal Society philosophy, Derham proposes that they spend the night in the farm so that they might observe the events and collect evidence.  It is a delightful suggestion from Derham, but we do not know whether Sloane ever took him up on his offer!

Citizen Science and Flying Ant Day, in 1707 and in 2013

“What the heck!?” I spat, as an ant flew into my mouth. The winged ants were everywhere: crawling on the ground or (seemingly) flying dozily around. It was a warm and humid afternoon and I envied the laziness of the ants. But I had a tube train to catch and I hurried off without paying them much attention. It was only when I arrived in the centre of London and spotted more ants that I began to wonder what was happening.

This was the U.K.’s famed ‘Flying Ant Day’ in which Queen Ants and the males take to the skies in their grandly titled nuptial flight. Although this annual event occurs wherever colonies of ants live, I had somehow never noticed it on the prairies of Canada–only discovering this natural spectacle about ten years ago while walking the urban pavements of London.

The 2013 rush has apparently already started, with ants in places as diverse as Cambridge and Nottingham already having had their day in the sun this week. There have also been several seagull traffic deaths in Devon, caused by the gulls gobbling down too much ant acid.

Last year, the Society of Biology enlisted the aid of “citizen scientists” to keep track of times, dates and weather conditions of sightings. What they found was that the nuptial flight occurs after a low pressure system and within a tight time frame, usually over a few days. The ants also make their flights between four and six in the afternoon.

The idea of citizen scientists compiling data for a scholarly society strikes me as, perhaps, rather familiar: early modern Royal Society anyone? William Derham (1657-1735), for example, was a clergyman by day and a “citizen scientist” by night—specifically, an astronomer—who kept Hans Sloane and the Royal Society apprised of his star-gazing. (I discussed Derham’s interests in another post.) Derham also passed on observations from other people, including Mr Barrett’s* account of flying ants in 1707.

I was lately at our friend Mr Barrets, who desired me to acquaint the Society concerning the Flights of Ants (that made such a noise in London last Sumer) that he hath for many years last past constantly observed the Flight of that Insect on the very same, or within a day or two of that very day of the Month, on which they fell in London. About the year 1689 or 1690 (as I remember) he said he saw a cloud of them, and several times since he hath seen the same. He took it for a Cloud full of Rain approaching towards him, & was much surprized to find it a vast Number of Ants only frisking in the Air, & carried aloft as he imagined only wth the gentle Current of the Air. He is of opinion that they allways come fromward the Westerly points. I hope our curious Members will for the future observe them more accurately, that we may make a judgment from what parts they came. The next day after they fell in London, I remember we had in divers places many of them, particularly at Mr Barrets, & South-Weal & Burntwood. I call them Flying-Ants, because Mr Barret (who is a good Judge) said they were such that he saw.

In 1707, people were as fascinated by the sight of flying ants as we are today, with the Flight causing quite a stir in London in 1706. Although observers weren’t even sure if the insects really were ants, or why they were flying in a mass, they were clear on three points: that it was a regular annual event, that air currents enabled the Flight, and that it occurred on multiple days across the south of England.

Over three-hundred years on, we’re rediscovering that Flying Ant Day is region specific in the U.K. and is affected by weather. It is intriguing that modern science still hasn’t explained the specific triggers for the Flight of Ants and has once again turned to citizen scientists to provide a larger data set for study. Despite Derham’s hope that “our curious Members will for the future observe them more accurately”, the Royal Society doesn’t appear to have taken much interest in the Flight of Ants. Maybe the Society of Biology will have more success.

If I happen to spot the Flying Ants this year, I plan to take part in the Society of Biology’s 2013 Flying Ant Day survey. This time, I’ll follow in the footsteps of Barrett and Derham by closely observing the natural world at my doorstep instead of dashing past it.

UPDATE, 22 July: The nuptial flight occurred in my London neighbourhood today, just before 5 p.m. I could not avoid observing nature on my doorstep, which had become a graveyard for a number of them. Here are two, caught in between a bit of flying around my garden. (And I did fill in my survey!)
