I was giving a course of simple lectures on physiology and hygiene at a club for working girls, which boasted much of its gymnastic classes and apparatus. After the lecture the girls often consulted me as to various symptoms from which they were suffering. One girl, sixteen years of age, I found to have heart disease, and a woman aged twenty-
