Collected Letters volume: 

This letter is known only by reference in Leeuwenhoek’s reply. The date is New Style, which was eleven days ahead of the Old Style date of 1 October 1722 used by Jurin in London. This letter is not calendared in Rusnock’s Correspondence of James Jurin.

Leeuwenhoek’s letters to Jurin about smallpox are Letter L-577 of 13 June 1722 and Letter L-579 of 7 July 1722.

Jurin, as secretary of the Royal Society from 1721 to 1727, edited volumes 31-34 of Philosophical Transactions, in which he published 15 of Leeuwenhoek’s final letters to him and to the Royal Society.


Letter L-581 of 20 November 1722 to James Jurin

Your letter, which you wrote to me on the 1st of October 1722, was given to me in good time, and was very pleasant. I have, then, understood from this that my hypothesis on pocks has found acceptance among you.
