My dear Carpenter

I have this minute finished your Review in the Med. Chirurg. Review.² You must let me express my admiration at this most able Essay, & I hope to God it will be largely read for it must produce a great effect.— I ought not, however, to express such warm admiration, for you give my Book, I fear, far too much praise. But you have gratified me extremely; & though I hope I do not care very much for the approbation of the non-scientific readers, I cannot say that this is at all so with respect to such few men as yourself.— I have not a criticism to make for I object to not a word; & I admire all, so that I cannot pick out one part as better than the rest. It is all so well balanced.— But it is impossible not to be struck with your extent of knowledge in geology, Botany, & zoology. The extracts which you give from Hooker seem to me excellently chosen & most forcible.³ I am so much pleased in what you say, also, about Lyell.—⁴

In fact I am in a fit of enthusiaism & had better write no more. With cordial thanks | Yours very sincerely | C. Darwin
