My dear Sir
I write to ask no more questions, but merely to thank you sincerely for your last, which has explained clearly all that I wanted to know.2 I have sent my MS. on “Domestic Animals, &c” to the printers, and it proves so terribly bulky that I have resolved not to include my Chapt. on Man; but as I have collected materials during several years on certain points (though so ignorant on other and perhaps more important subjects) in the Natural History of man I mean to publish a separate essay hereafter.3 I mention this merely that you might not think that your labours and kindness have been thrown away,—that is as far as I am capable of making use of them.4
My dear Sir | Yours sincerely & obliged | Ch. Darwin.
