My dear Huxley

My son William wishes to become a member of the Geological Soc^y.—¹ In old days anyone who felt an interest in Geology—(I can truly say that this is the case with my son, who has read much & observed for himself) was thought worthy of election.— If this be still the case, will you append your name to the enclosed certificate & return it in enclosed envelope.— If you will send it (together with this note) to M^r Judd,² perhaps he will sign it, & then it will be amply backed.

Ever yours sincerely | Ch. Darwin
