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 five folio pages, written and signed by Leeuwenhoek, is preserved at the Royal Society (MS. 1836. Early Letters L1.8).
Leeuwenhoek wrote this letter to Henry Oldenburg about worms and (possibly) protozoa in animal bile; metals, skin, bladders, and taste.
Dobell, p. 220, offers the descriptions in this letter as the first of the "Sporozoa or upon any parasitic protozoon ... oocysts of the coccidian Eimeria stiedae."
