Note 303 — Chapter XVIII · Friends of Boulton and Watt—The Lunar Society.

We find among the Boulton MSS., a letter from Priestley, dated Calne, 28th September, 1776, introducing Warltire to Boulton as follows:—“As I know you will take pleasure in everything in which the advancement of science is concerned, I take the liberty to recommend to you Mr. Warltire, who has been some time in this part of the country, and who is going to read lectures on the subject of Air at Birmingham. I think him an excellent philosopher, as well as a modest and agreeable man. He is perfectly acquainted with his subject, and has prepared a set of experiments which have given the greatest satisfaction wherever he has been. He has been so obliging as to spend some time with me, and has given me much assistance in my late experiments, of which he can give you some account.”
