Garvock. Bridge of Earn, Perthshire: September 4. My dear Mr. Darwin,--I hasten to relieve your mind about writing on vivisection, as I am sure that none of the physiologists would desire you to do so if you feel it a bother. After all, there are plenty of other men to do the writing, and if some of them quote the marked sentences in your letter (which I return), with the statement that you still adhere to them, the chief thing will be done--viz. showing again and emphatically on which side you are. It is not intended to call the article a 'Symposium.' I only used this word to show that they are to be of the same composite kind as those which the 'Nineteenth Century' previously published under this designation. Your letter gives me the first news of your brother's death. I remember very well seeing him one day when I called on you at his house. It must make you very sad, and I am sorry to have written you at such a time. I have already sent in a short review of Roux's book, but should like to see about the bees in 'Kosmos.' I am trying some experiments with bees here on way-finding; but, contrary to my expectations, I find that most bees, when marked and liberated at one hundred yards from their hive, do not get back for a long time. This fact makes it more difficult to test their mode of way-finding, as the faculty (whatever it is) does not seem to be certain. Many thanks for sending me the book on Worms so early. As yet I have only had time to look at the table of contents, which seems most interesting. Lockyer is staying here just now, and has given me the proofs of his book. It seems to me that he has quite carried the position as to the elements being products of development. Down: October 14. My dear Romanes,--I have just read the splendid review of the Worm book in 'Nature.' I have been much pleased by it, but at the same time you so over-estimate the value of what I do, that you make me feel ashamed of myself, and wish to be worthy of such praise. I cannot think how you can endure to spend so much time over another's work, when you have yourself so much in hand; I feel so worn out, that I do not suppose I shall ever again give reviewers trouble. I hope that your _opus magnum_ is progressing well, and when we meet later in the autumn I shall be anxious to hear about it. In a few days' time we are going to visit Horace in Cambridge for a week, to see if that will refresh me. Pray give my kind remembrances to Mrs. Romanes, and I hope you are all well. Garvock, Bridge of Earn, Perthshire: October 16, 1881.
