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 signed autograph on five quarto pages is in Gemeentearchief Delft (III B 58). It was not published during Leeuwenhoek's lifetime.


Leeuwenhoek wrote this letter about composition of the tophi of gouty patients. He also speculated erroneously on the causes of gout. In the second part of the letter, he wrote about how common salt crystals influence the human body. Finally, he wrote about his personal experiences with the beneficial effect of drinking tea when he was hung over from drinking too much wine.

Leeuwenhoek sent a copy of this letter, dated November 20, 1679, to Robert Hooke in London.
