Has written down what he gathered from HF on Tibetan dogs. Would welcome a few more details at any time, as he knows of nothing parallel to it.

My dear Falconer
I have written down what I gathered from you on Thibet Dogs; and if at any time you could add a few details, the case probably would be a very valuable & interesting one for me, as I know of nothing parallel to it.—f2
Yours most sincerely | Ch. Darwin
I enjoy so much a chat with you, that you will be sure to see me, when next in London.—f3
