He greatly enjoyed society, and had full opportunities for seeing the kind he liked best, the cream of the intellectual world of London, and perhaps one may be allowed to say that no one was ever more unspoilt by success, by popularity. He seemed to grow more simple, more single-hearted each year. The amount of work he did was very considerable. His books, 'Animal Intelligence,' 'Mental Evolution in Animals,' 'Mental Evolution in Man,' 'Jelly-Fish and Star-Fish,' 'Darwin and after Darwin,' 'An Examination of Weismannism,' represent an enormous amount of reading and thought; and besides all these, there was experimental work in University College and in his own laboratory in Scotland, and a succession of important articles in reviews, chiefly the 'Nineteenth Century,' 'Fortnightly' and 'Contemporary' Reviews, and 'Nature.'[24] It would be quite absurd to deny that Mr. Romanes liked a fair and free fight, and there was a good deal of scientific controversy, but he was absolutely incapable of anything but fairness, and never imported into private life any quarrel in print. He had plenty of stiff fights, chiefly with Mr. Thiselton-Dyer, Professor Lankester, and Mr. Wallace, but the first two were always his friends, and with the latter he had a very slight acquaintance. The following letter, though it belongs to a later date, will show his feelings on the subject of controversy: Christ Church, Oxford. Dear Professor Meldola,--I trust that our differences--and _disagreements_--as presented in 'Nature,' will not disturb our relations in private. Anyhow, I send the inclosed circular, which I am addressing to English biologists, and hope you will testify to your desire for 'facts' by signing the memorial. Yours truly, GEO. J. ROMANES. He lectured a good deal in provincial towns, and gave several Friday evening discourses at the Royal Institution. Lecturing, even in days of failing health, was always a pleasure, never a burden to him. The following letter is a mock triumphant description of a lecture in Glasgow, written purely to amuse his wife, and provoke some mock depreciatory remarks. Glasgow: 1880. Now for my news. Everything was splendid, much the best thing in the way of lecturing that I have done since Dublin,[25] and I was so sorry that you were not there. First of all we had a dinner given by my host in my honour, the guests being all the chief men in the University, including Professor Caird[26] and the biggest of all big swells, Sir W. Thomson.[27] The dinner was to me highly interesting, as I talked nearly all the time to Sir William, who is a wonderful psychological study.
