Antoni Cink wrote Letter L-517 of 2 July 1715 to Leeuwenhoek about his colleagues' reaction to Letter L-516 about muscle fibers
This letter is known only by reference in Leeuwenhoek’s reply.
In this letter, Antoni Cink told Leeuwenhoek about his recent activities. He showed Leeuwenhoek's letter about tendons and muscle fibers to two colleagues, who replied with a letter to Cink expressing their pleasure. Cink enclosed that letter.
In the following year, three professors at the university in Louvain would present Leeuwenhoek with a medal in honor of his achievements: Antoni Cink (1668-1742), professor of philosophy, Ursmer Narez (1678-1744), professor of medicine, and Hendrik Jozef Rega (1690-1754), professor of chemisty. See Letter L-535 of 12 June 1716 and Letter L-536 of 3 June 1716.
Cink’s previous letter to L. is Letter L-498 of October 1713, which he sent through Gerard van Loon. See that letter for an overview of the correspondence between Cink and Leeuwenhoek. Leeuwenhoek replied with Letter L-501 of 24 October 1713 refuting the ideas of Kircher and Letter L-516 of 26 March 1715 about tendons and muscle fibers.
Leeuwenhoek replied promptly to the present letter with Letter L-518 of 7 July 1715, also about tendons and muscle fibers. Cink’s next and last letter to Leeuwenhoek, Letter L-534 of 24 May 1716, was also signed by Narez and Rega.
Letter L-518 of 7 July 1715 to Antoni Cink
I have received from Louvain the very pleasant letter of Your Honour of the 2nd of July last, and in this I have seen the important activities of Your Honour; as well as the many most courteous expressions which Your Honour used in this. I gather, moreover, that Your Honour has communicated my letter concerning the tendons and little fibres of flesh to the very learned gentlemen Narez and Hage [Rega], both professors of medicine, who thereupon have sent to Your Honour in writing the expression of their pleasure, which document Your Honour has been so kind as to send to me under cover of the missive of Your honour. ...
Here, highly learned and highly esteemed sir, you have what I am able to say in answer to the letter which has been written to Your Honour by the highly learned and greatly esteemed gentlemen, professors of medicine, Narez and H. Rega.
