The Royal Society decided to resume correspondence with Leeuwenhoek
At a meeting of the Royal society on 22 April 1696 O.S., it was decided that the correspondence with L. ought to be activated, and that the secretary had to be informed of this (Journal Book Original, vol. 9, p. 226 and Sloane's drafts of meeting minutes for that day).
See Letter L-295 169 [102] of 10 July 1696:
I have duly received Your very polite and pleasant Letter of the 7th of February 169⅚, in which I saw the very polite expressions and encouragement used by you to communicate further discoveries of the secrets [of nature], and also that you had written another letter to me a few months ago.
I have to tell You that on the 5th of October 1693 I replied to a letter I had received from you shortly ago and that since that time I sent you eight different letters concerning my discoveries, to wit on the 20th of December 1693, on the 24th of January 1694, on the 24th of February, on the 2nd of March, on the 19th of March, on the 30th of April, on the 14th of september, all in the year 1694.
