The fact is becoming more palpable every year that there is an education appropriate to each sex; that identical education for the two sexes is so unnatural, that physiology protests against it and experience weeps over it. The physiological motto in education is, "Educate a man for manhood, a woman for womanhood, and both for humanity." Herbert Spencer, in speaking of the want of a proper course of education for girls, says: "It is an astonishing fact that, though on the treatment of offspring depend their lives or deaths, and their moral welfare or ruin, yet not one word of instruction on treatment of offspring is ever given to those who will, by and by, be parents." It will thus be seen, that as women have the care, the training and the education of children, they need an education in a special direction, and should have a very thorough one, to prepare them for the task. WOMEN SHOULD HAVE A KNOWLEDGE OF THE LAWS OF HEALTH. Physiology is one of the branches of that higher education, which should be thoroughly pursued by women to enable them to fulfill the various duties of their allotted stations. Yet it is also desirable that they should have a thorough knowledge of all branches that they undertake, and a mastery of the studies pursued by them; for the want of thoroughness in woman's education is an obstacle to success in all branches of labor. But woman should especially have a thorough knowledge of the laws of physiology and hygiene. If she becomes a mother, such knowledge will enable her to guard better the lives and health of her children. She will understand that when she sends out her child insufficiently clad, and he comes home chilled through, that his vitality, his power of resisting disease, is wasted. She will know that by taking the necessary precautions, she may save the child's life; that she must not take him thus chilled, to the fire or into a room highly heated, but that by gentle exercise or friction, she must restore the circulation of the blood, and in using such precautions, she may ward off the attacks of disease that would surely follow if they were neglected. This is but a single case, for there are instances of almost daily occurrence when a proper knowledge of the laws of health will ward off disease, in her own case, as well as in those of various members of her household. The diseases which carry off children, are for the most part, such as ought to be under the control of the women who love them, pet them, educate them, and who would, in many cases, lay down their lives for them.
