But then a peculiar thing happened. I became extraordinarily affected by the summer afternoons in the laboratory. The August sunlight came streaming in the great dusty fanlights and lay in yellow bars across the room. The old building ticked and creaked in the heat. Outside we could hear the cries of summer students playing touch football. In the course of an afternoon the yellow sunlight moved across old group pictures of the biology faculty. I became bewitched by the presence of the building
 for minutes at a stretch I sat on the floor and watched the motes rise and fall in the sunlight. I called Harry’s attention to the presence but he shrugged and went on with his work. He was absolutely unaffected by the singularities of time and place. His abode was anywhere. It was all the same to him whether he catheterized a pig at four o’clock in the afternoon in New Orleans or at midnight in Transylvania. He was actually like one of those scientists in the movies who don’t care about anything but the problem in their heads - now here is a fellow who does have a “flair for research” and will be heard from. Yet I do not envy him. I would not change places with him if he discovered the cause and cure of cancer. For he is no more aware of the mystery which surrounds him than a fish is aware of the water it swims in. He could do research for a thousand years and never have an inkling of it.
