Wrote Letter 7 of 1674-10-19 (AB 12) to Henry Oldenburg
October 19, 1674
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
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."
