Philosophical Collections number 5 published in London; one letter by Leeuwenhoek

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 late, but we do not know by how much.
