Philosophical society have done me the honor of naming me one of the Counsellors of that institution. if, at this distance, I can be useful to the society in any form, I ask nothing but the occasion of proving to them my readiness and zeal: and I beg the favor of you, Sir, to be the channel of conveying to them my renewed thanks for this and all other the marks of their favor for which I have so long and so often been indebted to them. to these permit me to add sincere condolances on the loss they have sustained in the death of our president; whose character was an ornament to our society, and his science precious to our country.
