that his experiments indicate that the use of alcohol, at least in the treatment of anthrax, tuberculosis, and diphtheria, is not only useless but probably injurious. From a number of other experiments carried out with scrupulous care he comes to the same conclusion as Abbott, Welch, and others that the predisposing to disease of alcohol must be explained by its action in producing abnormal conditions—pathological changes in the alimentary canal, liver, kidneys, heart, and nervous system. He found that the alkalinity of the blood was slightly diminished, and the number of leucocytes somewhat decreased. He also draws attention to the fact that his experiments prove that pregnant animals and their offspring are markedly affected by the continued use of small doses of alcohol. He shows, too, that the temporary lowering of the body temperature by alcohol produces the most favorable condition for the invasion of disease germs.
Since the publication of these experiments, and of others similar to them, the use of alcohol in diphtheria and tuberculosis has very largely ceased. Boards of health and charity organizations unite in warning against indulgence in alcoholic drinks as conducive to tuberculosis.
At the International Congress on Alcoholism, held in London in July, 1909, Professor Laitinen delivered two lectures. The first was upon "The Influence of Alcohol on Immunity." The following is taken from this lecture:—
