Dear Sir
I thank you for your obliging note.2 I am sorry to say that from my health not being strong & from having much to do I have made it a rule not to write in periodicals however valuable & eminent they may be.3
I thank you also for your communication with respect to the Microscopical Soc, which I will not forget, but it is not probable that I shall for some time attend to minute structure.4
I beg leave to remain | Dear Sir | Yours faithfully | Ch. Darwin.
