Dear Sir
I was lately in London, & was informed by some one (as he believed) that you had already started.—2 I then consulted Mr Sclater about the spare copy of your book, & he said he had just heard from Dr. Hartlaub (I do not know whether spelt rightly) the ornithologist, who much wanted a copy, & is a poor man, so I thought I cd. not do than hand it to Mr Sclater to forward.—3 I hope that this will meet with your approval.—
The point for enquiry is a very trifling one, viz whether Camels, when they utter a loud & prolonged sound, with violent expiration (& I have read that when loaded or ill-treated, they scream or groan loudly)—whether at the moment they contract their eyelids & skin round the eyes, as if shutting them violently;—or whether they do this in any degree.—4 In the Zoolog. Gardens the Camels never make any noise, so that I cannot observe this little point.
With my thanks for your kindness I remain | Dear Sir | Yours faithfully | Ch. Darwin
