Let the statement be emphasized and reiterated until it is heeded, that woman's neglect of her own organization, though not the sole explanation and cause of her many weaknesses, more than any single cause, adds to their number, and intensifies their power. It limits and lowers her action very much, as man is limited and degraded by dissipation. The saddest part of it all is, that this neglect of herself in girlhood, when her organization is ductile and impressible, breeds the germs of diseases that in later life yield torturing or fatal maladies. Every physician's note-book affords copious illustrations of these statements. The number of them which the writer has seen prompted this imperfect essay upon a subject in which the public has a most vital interest, and with regard to which it acts with the courage of ignorance. Two considerations deserve to be mentioned in this connection. One is, that no organ or function in plant, animal, or human kind, can be properly regarded as a disability or source of weakness. Through ignorance or misdirection, it may limit or enfeeble the animal or being that misguides it; but, rightly guided and developed, it is either in itself a source of power and grace to its parent stock, or a necessary stage in the development of larger grace and power. The female organization is no exception to this law; nor are the particular set of organs and their functions with which this essay has to deal an exception to it. The periodical movements which characterize and influence woman's structure for more than half her terrestrial life, and which, in their ebb and flow, sway every fibre and thrill every nerve of her body a dozen times a year, and the occasional pregnancies which test her material resources, and cradle the race, are, or are evidently intended to be, fountains of power, not hinderances, to her. They are not infrequently spoken of by women themselves with half-smothered anathemas; often endured only as a necessary evil and sign of inferiority; and commonly ignored, till some steadily-advancing malady whips the recalcitrant sufferer into acknowledgment of their power, and respect for their function. All this is a sad mistake. It is a foolish and criminal delicacy that has persuaded woman to be so ashamed of the temple God built for her as to neglect one of its most important services. On account of this neglect, each succeeding generation, obedient to the law of hereditary transmission, has become feebler than its predecessor. Our great-grandmothers are pointed at as types of female physical excellence; their great-grand-daughters as illustrations of female physical degeneracy. There is consolation, however, in the hope, based on substantial physiological data, that our great-grand-daughters may recapture their ancestors' bloom and force. "Three generations of wholesome life," says Mr. Greg, "might suffice to eliminate the ancestral poison, for the _vis medicatrix naturae_ has wonderful
