Philosophical Collections number 5 published in London, including Leeuwenhoek's Letter 35 of 1682-03-03 (AB 67) to Robert Hooke

February 1, 1682

This number of Philosophical Collections is dated February 1682. The previous two numbers had been published on the 10th of December 1681 and January 1682. This number 5 included a letter from Leeuwenhoek dated March 3, 1682, so this number was clearly late, but we do not know by how much.
