professor emeritus, retaining his precedence in the university. For a period of twenty-nine years he has been actively engaged in the teaching of his profession. Elected visiting physician to the Montreal General Hospital in February, 1856, he discharged the duties of that position until the year 1877, when he resigned, and was placed by the vote of the governors of that institution on the consulting staff. From 1868 till 1883 he had charge of the university lying-in hospital, to which he is now attached as consulting physician, and for a period of fourteen years he was physician to the Hervey Institute for children, to which charity also he is now consulting physician. He has always taken a warm interest in the literature of his profession, and articles from his pen have appeared in the _British American Medical and Surgical Journal_, the _Canada Medical Journal_, and the “Transactions of the Obstetrical Society of London, Eng.” In the year 1854 he, in conjunction with Dr. Wm. Wright, established and edited the _Medical Chronicle_ which had an existence of six years. He was vice-president for Canada of the section of Obstetrics in the ninth International Medical Congress, which was held at Washington during the week commencing September 5th, 1887. Dr. MacCallum married in October, 1867, Mary Josephine Guy, second daughter of the late Hon. Hippolyte Guy, judge of the Superior Court of Lower Canada. The Guy family, of ancient and noble origin, supposed to be a branch of the Guy de Montfort family, has been distinguished for the valuable services, military and civil, which its members have rendered to the province of Quebec, both under the old and new _régimes_. Pierre Guy, the first of the name to settle in Canada, joined the French army under M. de Vaudreuil, in which he rose rapidly to the rank of captain. He took an active part in the engagements which were then so frequent between the French in Quebec and the English in Massachusetts and New York. He died at the early age of forty-eight. His son Pierre, who was sent to France and received a thorough and careful education, also joined the French army and distinguished himself under General Montcalm at the battle of Carillon, and in the following year at Montmorency. The battle of the Plains of Abraham having annihilated the power of France in Canada, young Guy with others left for France after the capitulation of the country, where he remained till 1764. Returning to Canada, he accepted the situation, entered into business at Montreal, and became a loyal subject of Great Britain. Shortly after, when General Montgomery invaded Canada, he took up arms for the defence of the country, and this so exasperated the Americans that they sacked his stores after the capitulation of Montreal. In 1776 he received from the Crown the appointment of judge, which at that time was considered a signal mark of favour; and in 1802 he was promoted to the rank of colonel of militia. A
