organs of nutrition and secretion. You cannot draw water without good, flowing springs. _The brain and nervous system have, for a long time, made relatively too large a demand upon_ the organs of digestion and assimilation, while the exercise and _development of certain other tissues in the body have been sadly neglected_.... In consequence of the great neglect of physical exercise, and the _continuous application to study_, together with various other influences, large numbers of our American women have altogether an undue predominance of the nervous temperament. If only here and there an individual were found with such an organization, not much harm comparatively would result; but, when a majority or nearly all have it, the evil becomes one of no small magnitude."[15] And the evil, it should be added, is not simply the inability to nurse; for, if one member suffers, all the members suffer. A woman, whether married or unmarried, whether called to the offices of maternity or relieved from them, who has been defrauded by her education or otherwise of such an essential part of her development, is not so much of a woman, intellectually and morally as well as physically, in consequence of this defect. Her nervous system and brain, her instincts and character, are on a lower plane, and incapable of their harmonious and best development, if she is possessed, on reaching adult age, of only a portion of a breast and an ovary, or none at all. When arrested development of the reproductive system is nearly or quite complete, it produces a change in the character, and a loss of power, which it is easy to recognize, but difficult to describe. As this change is an occasional attendant or result of amenorrhoea, when the latter, brought about at an early age, is part of an early arrest, it should not be passed by without an allusion. In these cases, which are not of frequent occurrence at present, but which may be evolved by our methods of education more numerously in the future, the system tolerates the absence of the catamenia, and the consequent non-elimination of impurities from the blood. Acute or chronic disease, the ordinary result of this condition, is not set up, but, instead, there is a change in the character and development of the brain and nervous system. There are in individuals of this class less adipose and more muscular tissue than is commonly seen, a coarser skin, and, generally, a tougher and more angular make-up. There is a corresponding change in the intellectual and psychical condition,--a dropping out of maternal instincts, and an appearance of Amazonian coarseness and force. Such persons are analogous to the sexless class of termites. Naturalists tell us that these insects are divided into males and females, and a third class called workers and soldiers, who have no reproductive apparatus, and who, in their structure and instincts, are unlike the fertile individuals.
