My dear Gray
Many thanks for Nathusius recd safely.2 When in London I will call on you & shall be much obliged if you will tell me your views on the specific differences of pigs.3
I do not know who has cut me up so severely in the Ath: nor do I know whom you mean by the “great friend of John Murray.
From 2 or 3 little points I suspect the author to be your great man in the Museum—4
My dear Gray | yours sincerely | Ch. Darwin
