Hans Sloane wrote Letter L-388 to Leeuwenhoek about the reception of his recent letters in London
This letter is known only by reference in L.’s replies. The date is New Style, which was eleven days ahead of the Old Style date of 9 May 1701 used by Sloane in London.
In this letter, Sloane writes courteously to L. that his recent letters are translated, read to the Royal Society, and published in Philosophical Transactions.
The three letters L. refers to were all addressed to Sloane and translated by John Chamberlayne: Letter L-378 of 26 October 1700, Letter L-380 of 25 December 1700, and Letter L-382 of 28 January 1701.
Letter L-390 of 21 June 1701 to the Royal Society
In the letter of 9 May 1701, written to me by the secretary, Mr. Hans Sloane, I saw that my preceding discoveries pleased the Royal Society, which I was glad to learn.
Letter L-391 of 21 June 1701 to Hans Sloane
I saw in your letter of 9 May 1701 that my three letters had been received in good order and had been read at the meeting of the Royal Society as soon as they had been translated, and that they had pleased the Royal Society and that they sent me via you their (undeserved) thanks, and that they were to be communicated to the curious and ingenious noblemen of your nation, which I was pleased to learn.
