Welcome to The Sloane Letters Project

sloaneA pilot of this project, Sir Hans Sloane’s Correspondence Online, was first launched at the University of Saskatchewan in 2010 to coincide with the 350th anniversary of Sir Hans Sloane’s birth. The project was renamed The Sloane Letters Project when it moved to this site in 2016.

The correspondence of Sir Hans Sloane (1660-1753) consists of thirty-eight volumes held at the British Library, London: MSS 4036-4069, 4075-4078.  The letters are a rich source of information about topics such as scientific discourse, collections of antiquities, curiosities and books, patients’ illnesses, medical treatments and family history. Most of the letters were addressed to Sloane, but a few volumes were addressed to others (MSS 4063-4067) or written by Sloane (MSS 4068-4069).

So far, we have entered descriptions and metadata for Sloane MSS 4036-4053 and 4075, as well as several letters from each of the following: Sloane MSS 4054-4055, 4066, 4068-4069 and 4076. Several of these entries also include transcriptions. Further entries and transcriptions are being made available gradually.

Please, explore the website and database. You can search through the letters, learn about Sir Hans Sloane or the letters written to him, and peruse blog posts about interesting letters!

My Dearest Mistress,

The last time I had ye opportunity

to kiss your hand was ye only hap-py

day I have had these five years. And

might have been much more so, but yt it

secured at [least?], to set in a cloud. I long

to trye whether another day may not prove

more clear: If therefore you will give me leave

to wait on you tomorrow betwine 4 & 5 af-ternoone,

I shall much embrace yt joyfull

hour. This much Love [on:?] […]

write, yt you may Triumph over me,

as ye only Sovereigne of my heart. If

I had a hundred, they were all yours; &

had I as many hands, I would with every

one of them subscribe my self,

Mon Faire

Yr most passionate

& most obedient Captive
