I wonder how many men remember Tom Waterhouse Crabbe, student of medicine in this city. He was a man whom it was not easy to forget if you had once come across him. Geniuses are more commonly read about than seen, but one could not speak five minutes with Crabbe without recognising that he had inherited some touch of that subtle, indefinable essence. There was a bold originality in his thought, and a convincing earnestness in his mode of expressing it, which pointed to something higher than mere cleverness. He studied spasmodically and irregularly, yet he was one of the first men--certainly the most independent thinker--of his year. Poor Crabbe--there was something delightfully original even in his mistakes. I can remember how he laboriously explained to his examiner that the Spanish fly _grew_ in Spain. And how he gave five drops of Sabin oil credit for producing that state which it is usually believed to rectify. Crabbe was not at all the type of man whom we usually associate with the word "genius." He was not pale nor thin, neither was his hair of abnormal growth. On the contrary he was a powerfully built, square-shouldered fellow, full of vitality, with a voice like a bull and a laugh that could be heard across the meadows. A muscular Christian too, and one of the best Rugby forwards in Edinburgh. I remember my first meeting with Crabbe. It gave me a respect both for his cool reasoning powers and for his courage. It was at one of the Bulgarian Atrocity meetings held in Edinburgh in '78. The hall was densely packed and the ventilation defective, so that I was not sorry to find that owing to my lateness I was unable to get any place, and had to stand in the doorway. Leaning against the wall there I could both enjoy the cool air and hear the invectives which speaker after speaker was hurling at the Conservative ministry. The audience seemed enthusiastically unanimous. A burst of cheering hailed every argument and sarcasm. There was not one dissentient voice. The speaker paused to moisten his lips, and there was a silence over the hall. Then a clear voice rose from the middle of it: "All very fine, but what did Gladstone----" There was a howl of execration and yells of "Turn him out!" But the voice was still audible. "What did Gladstone do in '63?" it demanded. "Turn him out. Show him out of the window! Put him out!" There was a perfect hurricane of threats and abuse. Men sprang upon the benches shaking their sticks and peering over each other's shoulders to get a glimpse of the daring Conservative. "What did Gladstone do in '63?" roared the voice; "I insist upon being answered." There was another howl of execration, a great swaying of the crowd, and an eddy in the middle of it. Then the mass of people parted and a man was borne out kicking and striking, and after a desperate resistance was precipitated down the stairs.
