Corrigan's career should prove a stimulating example to the young physician just taking up that real post-graduate work in medicine which comes after he has received his degree, finished, perhaps, his hospital work, and is beginning his practice. Corrigan was only twenty-seven when he began the series of observations on which was founded his paper on aortic heart disease, which was published when he was about thirty. In this matter of youthful accomplishment, Corrigan is not alone among his distinguished Irish contemporaries. Stokes, it will be remembered, wrote his little book on the stethoscope when he was only twenty-one and had made some very important observations on disease of the chest before he had reached the age of thirty. Graves had showed very clearly the sound metal of his intelligence before he was twenty-five, and had described the cases of the nervous disease which have since come to be called after his name, Graves' disease, before his fourth decade had run more than a year or two. In fact these young men accomplished so much by their careful observation and dependence on their own resources that the medical writer of the modern times is tempted to wonder if perhaps that most precious {202} quality of the human mind in the young adult, its originality, is not obscured by the amount of information that it is expected to absorb before it is tempted to do any thinking for itself. There is another remarkable feature of Corrigan's achievement, in the recognition and description of this form of heart disease. At the time he was the physician to a hospital which had only room for six medical patients. This appointment to the little Jervis Street Hospital in Dublin had been secured only after competition, and Corrigan had to pay for the privilege of being the attending physician. This he could ill afford to do at the time, and so he resolved, as he told a friend, to make all his opportunities for the study of patients count to the greatest possible extent. He did not visit his hospital merely to see patients, but to study the cases carefully. His success is only another example of the necessity for seeing much, and not many things, if there is to be any real progress. In our day, physicians scarcely consider that they have any hospital experience unless they are the attending physicians to several hospitals, seeing at least one hundred patients a week. The result is that patients do not receive the skilled care they should, and that advance in medicine suffers because of the wasted opportunities for clinical observations while a busy attending physician rushes through a ward and the resident physician has only time for the routine work that enables him to keep just sufficiently in touch with the progress of his cases to satisfy the hurrying chief.
