Dear Sir
I beg your pardon for not having returned the proofs, which I now do, but I thought that they were spare copies.—2
I really have no criticisms or remarks worth sending which I could make in a reasonable space; & I have no strength or time to spare, as I am much out of health & am overworked at present with the tedious & dispiriting labour of preparing new Edits of 2 of my books.3
Pray forgive me, & believe me | Yours very faithfully | Ch. Darwin
