Dear D^r Wright

I am very much obliged for your note.¹ The fact that you mention about the buffalo diving is extremely curious & might come in of use to me, at some future day as illustrating abnormal habits. But I have one little difficulty   you speak of the animal as Buf. arnee; now the Arnee is a species of Bos & not of Bubalus; if you c^d at any time learn whether the animal was a Bubalus or a Bos your case w^d be more valuable.²

With very sincere thanks, pray believe me | Yours very sincerely | Ch. Darwin
