My dear Mr. Darwin,—
I am glad that you think the experiment worth trying. As you say you have not got the requisite apparatus for trying it, I have written to Professor Tyndall to see if he would allow it to be carried through at the Royal Institution.1
If I had known you were in town I should have called to tell you about the Echinoderms.2 My paper on them is now written (70 pages), so I have begun to come here (Burlington House) to read up systematically all the literature I can find on animal intelligence. Hence it is that, having left your letter at home, and not remembering the address upon it, I have to send this answer to Down.3
[Butler] is a lunatic beneath all contempt—an object of pity were it not for his vein of malice.4
Very sincerely and most respectfully yours, | geo. j. romanes.
