With an eye to its sexual mission, the female organism requires particular care,--good food, and, at certain periods, the requisite rest. Both of these are lacking to the great majority of the female sex, at least in the cities and industrial neighborhoods, nor are they to be had under modern industrial conditions. Moreover, woman has so habituated herself to privation that, for instance, numberless women hold it a conjugal duty to keep the tid-bits for the man, and satisfy themselves with insufficient nourishment. Likewise are boys frequently given the preference over girls in matters of food. The opinion is general that woman can accommodate herself, not with less food only, but also with food of poorer quality. Hence the sad picture that our female youth, in particular, presents to the eyes of the expert. A large portion of our young women are bodily weak, anaemic, hypernervous. The consequences are difficulties in menstruation, and disease of the organs connected with the sexual purpose, the disease often assuming the magnitude of incapacity to give birth and to nurse the child, even of danger to life itself. "Should this degeneration of our women continue to increase in the same measure as before, the time may not be far away when it will become doubtful whether man is to be counted among the mammals or not."[90] Instead of a healthy, joyful companion, of a capable mother, of a wife attentive to her household duties, the husband has on his hands a sick, nervous wife, whose house the physician never quits, who can stand no draught, and can not bear the least noise. We shall not expatiate further on this subject. Every reader--and as often as in this book we speak of "reader," we mean, of course, the female as well as the male--can himself further fill the picture: he has illustrations enough among his own relatives and acquaintances. Experienced physicians maintain that the larger part of married women, in the cities especially, are in a more or less abnormal condition. According to the degree of the evil and the character of the couple, such unions can not choose but be unhappy, and, they give the husband the right, in public opinion, to allow himself freedoms outside of the marriage bed, the knowledge of which throws the wife into the most wretched of moods. Furthermore the, at times, very different sexual demands of one party or the other give occasion to serious friction, without the so much wished-for separation being possible. A great variety of considerations render that, in most cases, out of all question.
