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.

If I had known you were in town I should have called to tell you about the Echinoderms. 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.

—— is a lunatic beneath all contempt—an object of pity were it not for his vein of malice.

Very sincerely and most respectfully yours,

Geo. J. Romanes.

18 Cornwall Terrace, Regent's Park, N.W.: December 17, 1880.

My dear Mr. Darwin,—Just a line to let you know that Professor Tyndall has kindly placed at my disposal the apparatus required to conduct the experiment with flashing light.

Frank's papers at the Linnean were, as you will probably have heard from other sources, a most brilliant success, as not only was the attendance enormously large and the interest great, but his exposition was a masterpiece of scientific reasoning, rendered with a choice and fluency of language that were really charming. I knew, of course, that he is a very clever fellow, but I did not know that he could do that sort of thing so well.

I have now got a monkey. Sclater let me choose one from the Zoo, and it is a very intelligent, affectionate little animal. I wanted to keep it in the nursery for purposes of comparison, but the proposal met with so much opposition that I had to give way. I am afraid to suggest the idiot, lest I should be told to occupy the nursery myself.

Very sincerely and most respectfully yours,
