It is impossible not to feel that had he stayed on at the University he would have devoted himself more and more to strictly experimental work and less to what may be called philosophical natural history. Some will regard his removal as a misfortune, and others as a happy accident, but the might-have-beens of life are never very profitable subjects for speculation. In order to be with his now widowed mother, he returned to London, and made his home with her and his sisters. They spent their summers at Dunskaith, and Mr. Romanes embarked on researches on the nervous system of the Medusæ. He began also to work in the physiological laboratory of University College under Dr. Sharpey and Dr. Burdon Sanderson. Both he regarded as masters and friends, and perhaps, next to Mr. Darwin, Dr. Sanderson was the scientific friend George Romanes most valued and loved, although it is impossible to overrate what he owed to Cambridge, and to those early longings for biological study which were inspired by Dr. Foster. As has been said, a letter in 'Nature' attracted Mr. Darwin's notice, and somewhere about 1874 he invited Mr. Romanes to call on him. From that time began an unbroken friendship, marked on one side by absolute worship, reverence, and affection, on the other by an almost fatherly kindness and a wonderful interest in the younger man's work and in his career. That first meeting was a real epoch in Mr. Romanes' life. Mr. Darwin met him, as he often used to tell, with outstretched hands, a bright smile, and a 'How glad I am that you are so young!' Perhaps no hero-worship was ever more unselfish, more utterly loyal, or more fully rewarded. As time went on, and intimacy increased, and restraint wore off, Mr. Romanes found that the great master was as much to be admired for his personal character as for his wonderful gifts, and to the youth who never, in the darkest days of utter scepticism, parted with the love for goodness, for beauty of character, this was an overwhelming joy. In a poem written about 1884 Mr. Romanes has expressed something of what he felt for Mr. Darwin, and in this he has poured out his 'hero-worship' in terms which were to him the expressions of simple truth. It is interesting to look over the long series of letters from 1874 to 1882 and notice how the formal 'Dear Mr. Romanes' drops into the familiar 'Dear Romanes,' and the letters become more and more affectionate, intimate, personal. About this time also Mr. Romanes made many other scientific friends, Professor Schäfer, Professor Cossar Ewart, Mr. Francis Darwin, Dr. Pye Smith, Professor R. Lankester, Professor Clifford, Dr. Lauder Brunton, and many more; and as his work became known it is pleasant to see with what kindness of welcome the new recruit was welcomed to the scientific army by such men as Professor Huxley, Sir John Lubbock, Sir Joseph Hooker, Mr. Busk, Mr. F. Galton, and Mr. Spottiswoode, then President of the Royal Society.
