I shall never forget the first time I saw him enter his lecture-room. He came in rapidly, yet without bustle, and as the clock struck, a brief glance at his audience and then at once to work. He had the excellent habit of beginning each lecture (save, of course, the first) with a recapitulation of the main points of the preceding one. The course was amply illustrated by excellent coloured diagrams, which, I believe, he had made; but still more valuable were the chalk sketches he would draw on the blackboard with admirable facility, while he was talking, his rapid, dexterous strokes quickly building up an organism in our minds, simultaneously through ear and eye. The lecture over, he was ever ready to answer questions, and I often admired his patience in explaining points which there was no excuse for any one not having understood.
Still more was I struck with the great pleasure which he showed when he saw that some special points of his teaching had not only been comprehended, but had borne fruit, by their suggestiveness in an appreciative mind.
To one point I desire specially to bear witness. There were persons who dreaded sending young men to him, fearing lest their young friends’ religious beliefs should be upset by what they might hear said. For years I attended his lectures, but never once did I hear him make use of his position as a teacher to inculcate, or even hint at, his own theological views, or to depreciate or assail what might be supposed to be the religion of his hearers. No one could have behaved more loyally in that respect, and a proof that I thought so is that I subsequently sent my own son to be his pupil at South Kensington, where his experience confirmed what had previously been my own.
As to science, I learnt more from him in two years than I had acquired in any previous decade of biological study.
