Philosophical Collections number 5 published in London, including Leeuwenhoek's Letter L-116 of 1682-03-03 to Robert Hooke
Date:
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 actually published later than its official date of February, but we do not know by how much.
