Wrote letter of 1710-06-06 (AB 284) to Members of the Royal Society

Leeuwenhoek's self-publications are the source for the summaries of his 165 letters self-published and thus self-numbered letters. This letter was not among them.

Of the letters from April 4, 1702 (AB 237) through June 10, 1712 (AB 294), those letters with scientific observations, including this one, were all addressed to members of the Royal Society and almost all of them were excerpted in Philosophical Transactions.
