neuralgia and hysteria, irregular menstruation, leucorrhea, atrophy of sexual organs. He also refers to the frequency of myoma of the uterus among those who have not become pregnant or who have long ceased to bear children. (Balls-Headley, art. "Etiology of Diseases of Female Genital Organs," Allbutt and Playfair, _System of Gynæcology_, 1896, p. 141.) It cannot, however, be said that he brings forward substantial evidence in favor of these beliefs. It may be added that in America, during recent years, leading gynecologists have recorded a number of cases in which widows on remarriage have shown marked improvement in uterine and pelvic conditions. The question as to whether men or women suffer most from sexual abstinence, as well as the question whether definite morbid conditions are produced by such abstinence, remains, however, an obscure and debated problem. The available data do not enable us to answer it decisively. It is one of those subtle and complex questions which can only be investigated properly by a gynecologist who is also a psychologist. Incidentally, however, we have met and shall have occasion to meet with evidence bearing on this question. It is sufficient to say here, briefly, that it is impossible to believe, even if no evidence were forthcoming, that the exercise or non-exercise of so vastly important a function can make no difference to the organism generally. So far as the evidence goes, it may be said to indicate that the results of the abeyance of the sexual functions in healthy women in whom the sexual emotions have never been definitely aroused tend to be diffused and unconscious, as the sexual impulse itself often is, but that, in women in whom the sexual emotions have been definitely aroused and gratified, the results of sexual abstinence tend to be acute and conscious.
