|'Referring to your letter of November 17, Mark Cetesby was elected a Fellow of the Royal Society on April 26, 1733.
Apparently all we have here relating to him is his certificate of election and two entries in the Council Minutes referring to various drawings that he executed for the Society. These would not doubt be interesting as matters of family history and you might see them if you cared to call here. It would no be convenient, however, to come here on Thursday, November 30, as meetings are to be held on that day. The best course would be to name a day and time, between 11 a.m. and 6 p.m.'
