Psychiatrists, Neurologists and the Neurosurgeon *

Permit me at once to convey Yale's greetings to McGill on the occasion of this highly significant ceremony. At the same time, since I have been asked to speak briefly about the surgery of the nervous system, I may, unsolicited, venture to bring to you the felicitations of the enlarging group of surgeons who restrict themselves to this specialty in our two adjoining countries. The frontiers which separate us are of concern only to politicians, cartographers, and customs officers. To the medical profession-there being no tariff on our exchange of doctors and nursesthey are to all intents and purposes non-existent. We, on our side of the line, continue to be vastly in Canada's debt for sending us, among others, the incomparable Osler. It was his Textbook that aroused the interest of Mr. Rockefeller in Medicine and led to the establishment of the foundation bearing his name, which in turn has made possible the erection of this institute, whose director we have thrown in for good measure. Even so, the account is by no means yet squared. On three former occasions I have naively undertaken to review the existing status of neurological surgery; once in 1904, again in 1909, and for the third time just after the Great War. I shall spare you from any such undertaking now, but the last of these paperst ended with the account of a project which may serve as a suitable text for my brief address to-day. As the War drew to a close, a small group of overseas medical officers, whose official positions had thrown them closely together, found themselves disinclined to return to their former humdrum professorial tasks. In talking the matter over they conceived the idea of founding a national institute of neurology whose primary purpose was to aid the government in supervising the further treatment of the disorders and injuries of the nervous system sustained
