To these must be added Sir Dominic Corrigan (1802-1880), the first Catholic to occupy the position of President of the College of Physicians in Dublin, an authority on heart disease, and the first adequate describer of aortic patency, a form of ailment long called "Corrigan's Disease". "Colles's Fracture" is a familiar term in the mouths of surgeons. It derives its name from Abraham Colles (1773-1843), the first surgeon in the world to tie the innominate artery, as "Butcher's Saw", a well-known implement, does from another eminent surgeon; Richard Butcher, Regius Professor in Trinity College in the seventies of the last century. Sir Rupert Boyce (1863-1911), F.R.S., though born in London, had an Irish father and mother. Entering the medical profession, he was assistant professor of pathology at University College, London, and subsequently professor of pathology in University College, Liverpool, which he was largely instrumental in turning into the University of Liverpool. He was foremost in launching and directing the Liverpool School of Tropical Medicine, which has had such widespread results all over the world in elucidating the problems and checking the ravages of the diseases peculiar to hot countries. It was for his services in this direction that he was knighted in 1906. Sir Richard Quain (b. Mallow 1816, d. 1898), F.R.S., spent most of his life in London, where he was for years the most prominent physician. He wrote on many subjects, but the _Dictionary of Medicine_, which he edited and which bears his name, has made itself and its editor known all over the world. Sir Almroth Wright (b. 1861), F.R.S., is the greatest living authority on the important subject of vaccino-therapy, which, indeed, may be said to owe its origin to his researches, as do the methods for measuring the protective substances in the human blood. He was the discoverer of the anti-typhoid injection which has done so much to stay the ravages of that disease. ENGINEERING. Bindon Blood Stoney (1828-1909), F.R.S., made his reputation first as an astronomer by discovering the spiral character of the great nebula in Andromeda. Turning to engineering, he was responsible for the construction of many important works, especially in connection with the port of Dublin. He was brother of G. J. Stoney. Sir Charles Parsons (b. 1854), F.R.S., fourth son of the third Earl of Rosse, is the engineer who developed the steam turbine system and made it suitable for the generation of electricity, and for the propulsion of war and mercantile vessels. If he has revolutionized traffic on the water, so on the land has John Boyd Dunlop (still living), who discovered the pneumatic tire with such wide-spread results for motorcars, bicycles, and such means of locomotion.
