My dear Sir

I must have the pleasure of thanking you for your note. I quite agree with your remarks on Prof. A. Gray's pamphlet: it is in my opinion the ablest thing which has appeared.— It is very kind of you to send me the pamphlet, which I will shortly read.— In a new Edit of Origin, which will immediately appear, I have enlarged a little on the relation of the most diverse types & on a few other subjects.

Mr Paget of London told me of the singular fact of the discolouration of the skin in relation to the state of the supra-renal capsules. Also of the singular state of the teeth in inherited secondary Syphilis.— But your fact of ``clubbed finger nails in Cyanosis'' is quite new to me. If you would not think me quite unreasonable, I shd. be very much obliged for a little more information. What is cyanosis? Is it due to disease of heart? Which way are nails modified. Does the modification appear at birth? Is it an inherited disease?

Pray excuse me troubling you & believe me Dear Sir with many thanks | Yours sincerely | <Charles Darwin>
