Letter 1033

[fol. 130] Sr Upminster Feb. 4 1705/6 I have sent you your Mersenne, & one of the 2 Vol. you lent me of the Acta Erudit., toge- ther with a thousand thanks for the use of them. You should sooner have read them but U have not been nor sent to London since I saw you. If my man finds you at home, I desire you will come see me the Lr of Mr —— about Easter, remember you read to the Society when I was last there, & wch the President took to examine you shall have it again with all safety & speed. I have looked over some collections I had on yt subject, and I think am able to put all matters out of doubt on that subject. Dr Wallis is certainly out in his account, & Mr Thorton not fully right in his, wch are published in the Transactions; & I want to see what that Gent says in the Lr I desire of you If you think a short Dissertation on that subject ground and on undoubted Antiquity & the best Records would be acceptable. I would draw it up & send you. I herewith also send you a farther account of some Magneticall experiments wch I take to be new usefull & I hop will be [accep]table diversions to you & the Society. I am perfecting my experiments about the flight of Sounds, which are to be long. I intend to impart to the So- ciety , & I hope to their satisfaction. Your matters are well as Orset, only the Brewhouse wanteth some Rafters & Thatch to defend that building again to the winter weather. I desire my humble service may be accepted by your Lady. I am Sr your much obliged humble servant Wm Derham This minute the mans wife at Orset who looks after your Farm is come hither, & tells me yt there are 3 or 4 young Ashes cut down in your Grove, & about as many young Elms in the Hedges.
