My dear Sir

I received from Down this morning the Paper on the R. Negro.—¹ I see by your note that it was sent from your office, on the very day, on which I left home.— I have given the best opinion I could on the Paper.— It appears to me pleasantly written, but most of the information might be found, scattered in other pub-lications. I found it impossible to mark out whole passages, as you requested.

Pray believe me | Yours very truly | C. Darwin Colonel Jackson
