cause, generally coming on after slight exertion. There must have been the microbe of influenza, influencing the muscle. or nerve of the heart, which causes these sudden deaths, or, perhaps, something influencing the nourishment of the heartmuscle. Another cause of the increased number of deaths from heart disease which may be mentioned is the late hours, which results in a short amount of sleep. When I first went to Philadelphia in 1859 they had three theaters there. Now they have over 50, and yet the population has not increased more than fourfold. This shows how the people are more generally supporting the drama. They go to the theaters; then follows a midnight supper, and as a result they do not get to their beds until early morning. Some of them keep this up night after night, and it all has its effect upon the strength, and incidentally the heart, especially upon the daily toilers who become overwearied. I feel that the rapid trains, automobiles and bicycles are a disadvantage in adding to the strain upon the heart. Again, roller skating, which comes and goes as a fad; athletics in the young, as well as early dancing, are often the beginning of trouble. Keeping on with the social procession, rapid eating, as well as overeating, and too much rich food, with too free use of alcohol, the haste to be rich, cigarette smoking are among the causes of cardiac disease. Dr. Carroll E. Edson, Denver: The factor of general vascular strain is one we ought to consider. I think we do not all realize how early this begins. The question of trouble in the heart does not begin, so far as successful treatment is concerned, when the degenerative change starts in the vascular wall. It is the preceding period of physiologic hypertension which is important to recognize, that condition of strain which is brought about, in part, by our manner of life, and coming not only in middle life, but beginning far back in early manhood and womanhood, even in childhood, as we now see in the way that our youths and children live. There is a constant whirl of fraternities and societies, even with the young people. They have college and highschool fraternities, and probably next they will have kindergarten fraternities. It is within a year that there came to my knowlelge a lunch party given for boys and girls from 12 to 14 years of age, and they began with small cocktails and then their childish appetites were stimulated with caviar. When children of 10 or 12 begin life in this way there is no wonder that the figures in the increase of heart diseases show such alarming proportions. 1 INDEX MEDICUS. KEY TO MEDICAL PERIODICALS.
