His years in Parliament, however, did not separate him from his interests either in medicine or in general science. He continued to be especially interested in zoology and made liberal contributions to the Dublin Zoological Garden. His residence at Dalkey, the grounds of which ran down to a rocky coast line, enabled him to obtain many specimens for his aquarium, and these were often transferred to the Dublin Zoological Gardens, for which he was one of the most active collectors. It was his custom during his Parliamentary career, though he was more than seventy, to leave London on Friday night and reach Dublin about eight o'clock on Saturday morning. From the station he went directly to the Zoological Gardens and took part in the pleasant breakfast which the Council of Officers of the Zoological Society, with some invited guests, had there every Saturday morning. He was noted for his humor, and his presence at these breakfasts was always appreciated, because in spite of his advancing years he was sure to add to the pleasure of the occasion. His friends feared that his Parliamentary career might prove a serious drawback to his health at his time of life, and their fears were not without foundation. He suffered severely from gout, which left its marks upon his feet and made it very difficult for him to walk for a time, and maimed him for all his after-life. Though a man who had worked very hard all his life and who, at the age of seventy, practically took up another career, that of politics, Sir Dominic lived to be nearly eighty years of age; thus illustrating the old aphorism that "it is not work but worry that kills," and {212} furnishing another example of the fact that great men are great also in their superabundant vitality, and are able to spend their lives in the hardest kind of work, yet, barring accident, live on to an age beyond even that which is considered the average term of human existence. Few men have had happier lives than Corrigan, if the high esteem of contemporaries can ever confer happiness. There was no honor in the gift of his Dublin professional brethren or of scientific bodies in which he was interested which was not conferred upon him. He was the president of the Royal Zoological Society, the president of the Dublin Pathological Society, of which he was one of the founders, and the first president of the Dublin Pharmaceutical Society. When not yet fifty years of age he was made physician in ordinary to the Queen in Ireland, and had the unapproached record of five elections to the presidency of the King and Queen's College of Physicians in Dublin--more than enough to make up for the one serious setback in his medical career, his black-balling by the college only a few years before. Foreign medical societies invited him to honorary membership and foreign universities conferred many degrees on him.
