[The year 1882 was a dark year for English science. It was marked by the death of both Charles Darwin and of Francis Balfour, the young investigator, of whom Huxley once said,] "He is the only man who can carry out my work." [The one was the inevitable end of a great career, in the fulness of time; the other was one of those losses which are the more deplorable as they seem unnecessary, the result of a chance slip, in all the vigour of youth. I remember his coming to our house just before setting out on his fatal visit to Switzerland, and my mother begging him to be careful about risking so valuable a life as his in dangerous ascents. He laughingly replied that he only wanted to conquer one little peak on Montblanc. A few days later came the news of his fatal fall upon the precipices of the Aiguille Blanche. Since the death of Edward Forbes, no loss outside the circle of his family had affected my father so deeply. For three days he was utterly prostrated, and was scarcely able either to eat or sleep.

There was indeed a subtle affinity between the two men. My mother, who was greatly attached to Francis Balfour, said once to Sir M. Foster, "He has not got the dash and verve, but otherwise he reminds me curiously of what my husband was in his 'Rattlesnake' days." "How strange," replied Sir Michael, "when he first came to the front, Lankester wrote asking me, 'Who is this man Balfour you are always talking about?' and I answered, 'Well, I can only describe him by saying he is a younger Huxley.'"

Writing to Dr. Dohrn on September 24, Huxley says:—]

Heavy blows have fallen upon me this year in losing Darwin and Balfour, the best of the old and the best of the young. I am beginning to feel older than my age myself, and if Balfour had lived I should have cleared out of the way as soon as possible, feeling that the future of Zoological Science in this country was very safe in his hands. As it is, I am afraid I may still be of use for some years, and shall be unable to sing my "Nunc dimittis" with a good conscience.]

Darwin was in correspondence with him till quite near the end; having received the volume "Science and Culture," he wrote on January 12, 1882:—

With respect to automatism (The allusion is to the 1874 address on "Animals as Automata," which was reprinted in "Science and Culture."), I wish that you could review yourself in the old, and, of course, forgotten, trenchant style, and then you would have to answer yourself with equal incisiveness; and thus, by Jove, you might go on ad infinitum to the joy and instruction of the world.

And again on March 27:—

Your most kind letter has been a real cordial to me…once again accept my cordial thanks, my dear old friend. I wish to God there were more automata in the world like you.

Darwin died on April 19, and a brief notice being required for the forthcoming number of "Nature" on the 27th, Huxley made shift to write a brief article, which is printed in the "Collected Essays" 2 page 244. But as neither he nor Sir Joseph Hooker could at the moment undertake a regular obituary notice, this was entrusted to Professor Romanes, to whom the following letters were written.]
