IT IS A PRIVILEGE of the practice of medicine to pursue the "dying ideal," so beautifully portrayed by Wilfred Trotter,1 when he said that "an occupation for adults should allow of intellectual freedom, should give character as much chance as cleverness, and should be subject to the tonic of difficulty and the spice of danger." The variety of medicine and its texture are a considerable remove from the artificial neatness of lecture and textbook. Alert and enquiring minds are needed to foster expert and happy practice. In training for this occupation for adults, it is to be hoped that the student in his own good time will pass beyond the preliminary stage of precept and rule, when the going is monotonous and seems likely to be ever so.* Innumerable facts must be accumulated and integrated, as there is pieced together what eventually seems like nothing so much as a jigsaw puzzle.
