Jacob Gronovius wrote to Leeuwenhoek about how his letters were received in Italy

July 11, 1686

In Letter 96 of 1686-10-30 to Magliabechi, Leeuwenhoek wrote,

The very learned Jacob Gronovius writes to me from Leiden, dated 11th July, that Your Honour has several times made mention of me in his letters, from Florence, and of the respect which you, most Ill., bears towards me, with further expressions of courtesy, for all of which honour that is done me, because of my modest work in discovering mysteries hitherto concealed.
