Text of the letter in the original Dutch and in English translation from Alle de Brieven. The Collected Letters at the DBNL - De Digitale Bibliotheek voor de Nederlandse Letteren.

The original manuscript on six quarto pages, written and signed by Leeuwenhoek, is preserved at the Royal Society (MS. 1895. L 1. 66). Of the 15 letters that he addressed to Robert Hooke, this letter is the last one that we have and the last one that was published.


No figures illustrated this letter. It was the only letter numbered by Leeuwenhoek for the decade from Letter 28 of April 25, 1679, through Letter 67 of April 1, 1689, that did not have figures. Many of its observations, such as muscle fibers, were of the kind that were illustrated in other letters. Perhaps these images were beyond Leeuwenhoek's skill and a suitable draftsman was not available.
