himself a follower of Hahnemann's unorthodox and mistaken doctrines. In 1842 it fell to Simpson's lot to deliver the customary address to the medical graduates after they had received their degrees at the annual ceremonial on the 1st of August. He treated his listeners to a discourse on the duties of young physicians. When we remember that he had attained to his then high professional position while he was no more than a young physician himself, we recognise that he was but setting forth the ideals and principles which had been and still were his guides in life and conduct. After warning his audience against regarding the gaining of the coveted degree as the end of their student career, instead of as in reality the opening up of a lifetime of observation and study, he pointed out that self-patronage was the best of all patronage. "Place from the first," he said, "all your hopes of advancement upon the breadth and extent of your medical abilities alone.... Rather walk by the steady light of your own lamp than by the more dazzling, but to you more uncertain, lustre borrowed from that of others ... Young physicians often dream that by extending the circle of their private acquaintances they thus afford themselves the best chance of extending the circle of their private patients.... No man will in any case of doubt and danger entrust to your professional care the guardianship of his own life or of the life of those who are near and dear to his heart, merely because you happen to be on terms of intimacy with him. The self-interest of human nature forbids it.... The accomplishments which render you acceptable in the drawing-room are not always those that would make your visits longed for or valued in the chamber of sickness and sorrow.... Give therefore your whole energies to medicine; and in its multiplied departments you will find 'ample room and verge enough' for the most energetic as well as the most comprehensive mind. Place your faith in no extrinsic influences. Let your own professional character be the one great patron to whom you ever look for your professional advancement." He exhorted the young practitioners above all to save and economise their time, and to regard it as a property to be avaricious of and of every item of which they were to render a proper account to themselves. "It is by carefully preserving, confirming, and making diligent use of these broken and disjointed portions of it, which others thoughtlessly waste and destroy, that almost all the highest reputations in the medical profession have been formed." He strongly urged the value of a "proper covetousness of time." "Look around, and you will find that those who have the most to do in the way of business as practitioners have also apparently the most time to spare as observers and writers.... And why? Because they have all their daily duties perfectly assorted and arrayed; they save from loss and destruction every possible fragment
