Mr. Waller’s Answer, to the
foregoing Letter, dated July 8, 1714

Worthy Sir

Yours of the 22d past we received, which being read in the next meeting of the Royal Society I was ordered to return you the thanks of the Society for that and your former communications and to desire the continuance of the like favor from you. And to assure you that (when you seem to doubt whether the Society were fully satisfyed as to some of your observations on the minute fibrilla of the flesh fibres of a muscle) the Society never had the least ___pts as to the truth of those or any other of your microscopical Discoverys, many of which have indeed to some persons at first seemed wonderfull, But Time and future observations have always verified them and reconcild the scrupulous Inquirer to your __pertions: In my last indeed I proposed the small muscles of insects to your Inquiry, the generallity of those creatures having as I may say their Bones on the outsides of their limbs so I thought it possible that there might be some other peculiar mechanisme for the moving of them, which I venture to recommend to your further Enquiry, and if you please to send the delineation of the fibrilla of the muscles of the fly with those of larger animals which you mention you have before your microscope you may be assured of a gratefull acceptance.

As to what you mention in your last of the delineations of the small fibres of a muscle not being publishd in the Transactions, you will find the letter those figures belong to has not yet been printed. In the next Transactions that are publish’d which I purpose shortly to undertake, I shall take care to have them well graved and inserted. Any other curious discovery you shall please to communicate to the Society shall be faithfully translated and read in our publick meetings and the Society’s answer transmitted to you as soon as possible by me who shall allways esteeme it as a particular happyness to have any opportunitys of shewing how much I am Sr

your most humble etc

P.S. Sr. for the future you need not give yourself the trouble of having your Letters translated into Latine But may express yourself as formerly in your own Language there being several gentlemen of the Society who will think no trouble to translate Mr. Leeuwenhoek’s Letters.

The Society have ordered a present of the last vol. of the Philosophical Transactions which shall be sent the first opportunity.
