connected with that aristocratic class known in Ireland as “Castle Catholics.” His mother, who was born at Ferhill Castle, Blackwater, county Clare, was also closely allied by ties of blood to the famous fighting “Goughs of Clare,” whose name is historical through General Gough, of India fame. Dr. Gaynor is the eldest member of a family of twelve, eight of whom are still living. One of his brothers, the Rev. William C. Gaynor, is Roman Catholic pastor of Richmond, in Carleton county, New Brunswick. Father Gaynor is a writer of great power on theological questions, and is the author of “Papal Infallibility,” published in 1885, and of a Commentary in Latin on the _Summa Theologica_, of Thomas Aquinas, now in press in Paris. Another brother, P. A. Gaynor, is a member of a large lumbering house in Pennsylvania, and is now in the Redwood district of California, where he has established a branch firm. Dr. Gaynor was educated partly at St. Michael’s College, Chatham, and partly at St. Joseph’s College, Memramcook. In the former institution he studied mathematics and the exact sciences under the most distinguished teacher of his day in New Brunswick, Thomas Caulfield, M.A., of Trinity College, Dublin. His subsequent studies in logic and metaphysics were pursued at St. Joseph’s College, Memramcook. In this institution he taught the higher mathematics. It was here also that in 1877 he began the study of medicine under the preceptorship of Dr. H. E. Boissy, resident physician to St. Joseph’s, and leading medical practitioner among the Acadians of New Brunswick. From St. Joseph’s Dr. Gaynor went in 1878 to Buffalo, New York. There he attended the lectures in the medical department of Buffalo University. He followed also the different courses of the newly established College of Physicians and Surgeons in the same city. Graduating in 1881, after a four years’ course, he carried off the honours of his class, and was immediately offered the chair of chemistry and toxicology in his _alma mater_. This honourable position he declined at the insistance of his friends in New Brunswick, and immediately returned to his native province. Shortly after his return he read by invitation a paper on “Chloroform as an Anæsthetic,” before the Medical Society of New Brunswick. Establishing himself at DeBec, Carleton county, he soon acquired a lucrative practice. It was here that for the first time in the history of medicine in New Brunswick nitro-glycerine was employed, by Dr. Gaynor, for remedial purposes. Finding that his sphere of labour was too circumscribed, and desirous of entering into a larger field, Dr. Gaynor removed, in 1884, to St. John city, where he has since resided. On February 20, 1884, he was united in the bonds of holy wedlock to Nora Costigan, of St. John, a relative of the Hon. John Costigan, Minister of Inland Revenue. By her he has three children—Walter and Frederick, born February 16, 1885, and James, born August 28, 1886.
