largest ward, and from that position to point out every patient therein who had been taking stimulants for three or four days at least, and I succeeded. To me the pale worn aspect of the patient is unmistakable.
With this I end my paper. It is not for me to go into statistics on the point, such as may be found, I dare say, in books or hospital reports. I know that such statistics are scant, for the question has not yet become a matter of calm scientific investigation. It is still one of the "fads" of the day, which the practical physician has not time to trouble about. Nevertheless, the reform is irresistibly advancing. No one can overlook the unmistakable diminution of the consumption of alcoholic liquors in hospitals. This is probably due in great measure to the greater temperance of the general community — a change of fashion rather than a reform of practice. It has been said long ago that the evils wrought by a theory have never in history discredited the theory; and certainly this would seem to be true in the practice of medicine. The melancholy history of the use of calomel and of opium in India is a saddening illustration. A few men here and there question the theory, and gain adherents chiefly among the young. The older men are not so much converted. They die out, and by and by the world awakes and exclaims how foolish the last generation was.

Such a state of affairs, sufficiently dangerous in any society, is simply suicidal in the democratic civilization of our day."
That the check to progress here indicated is a real one few will
