After Corrigan's death in 1881 the London _Lancet_ said: "In the light of recent pathology Corrigan's speculations on cirrhosis of the lungs are more meritorious than ever and continue to be regarded as in the main sound. They anticipated by forty years much of the present pathology." Needless to say it is only a genius of a very high order that is thus capable of rising above the limitations of environment, and in spite of the defective knowledge of his times observing correctly and drawing proper conclusions, though all the usual accepted principles would seem to be sure to lead him from the truth. The principal lesions of chronic pneumonia, after having been the subject of much disputation, with conclusions now one way and now another in the intervening years, are at the present time recognized as being essentially due to the pathological processes Corrigan originally pointed out. The man who thus made a permanent place for himself in the history of medicine was the son of a poor shopkeeper in one of the outlying districts of Dublin. His early education was obtained at Maynooth College, which had at that time a department for the training of youth for secular vocations, though it has since become an exclusively clerical institution. It is needless to say he acquired an excellent knowledge of the classics, of which he made abundant use later in life, and of which he was always very proud. The physician in attendance at Maynooth in his time took quite a liking to him, and it was the result of his suggestion that Corrigan took up medicine as his profession. For a time {208} he was under the tutelage of this Doctor O'Kelley, who seems to have been a very intelligent man, and a rather painstaking clinical observer. Most of his medical studies were made in Dublin and he attended the practice at Sir Patrick Dun's Hospital. It was the fashion at this time, however, for Irish students of medicine to finish their medical education at Edinburgh, whenever possible, and Corrigan spent several years there, receiving his degree of Doctor in Medicine in 1825. He had attracted considerable attention in Edinburgh for his acute powers of observation, and received an appointment to the Meath Street Dispensary shortly after his return. From the service here he was appointed to the Jervis Street Hospital. He had to pay, however, for the privilege of being attending physician here, and this, as he said, made him more careful in endeavoring to secure all the advantages possible from his service.
