I can quite comprehend the difficulty you mention about not knowing what is known zoologically in India; but facts observed, as you will observe them, are none the worse for reiterating.

Did you see Mr.Blyth in Calcutta?
He would be a capital man to tell you what is known about Indian Zoology, at least in the Vertebrata.

He is a very clever, odd, wild fellow, who will never do what he could do, from not sticking to any one subject.

By the way, if you should see him at any time, try not to forget to remember me very kindly to him; I liked all I saw of him.

Your letter was the very one to charm me, with all its facts for my Species-book, and truly obliged I am for so kind a remembrance of me.
