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 optic nerves and sight.
1 in red chalk - cross-section of cow's optic nerve
A, B, C, D is the circumference of the Optie Nerve, which did not dry round-ways, but somewhat oblong on the side C, D.
E, and all the places that are left white and lucid, are cavities in the dried Nerve, and which I imagine to have been filaments, and out of which, for the greatest part, the soft globuls have been exhaled.
F, are particles or globuls, which are in the little holes of the filaments in many places, and such as have not been exhaled: Of which some do lie on the side of the hollownesses, others lie round about a cavity, others lie cross a cavity, as G. All these particles were eminently transparent.
About A, B, C, D, there are near the edge of the Nerve some transparent winding stroaks.
