The second consideration referred to is this: As medical instruments multiply, diseases appear to multiply in exact proportion. With the advent of the ophthalmoscope, for instance, how innumerable and complicated appear the diseases of the eye. Are we justified in concluding, then, that in the "good old times" of our great-grandmothers--that idyllic time when women must have been at least free from the reproach that they, solely and unaided, were destroying the hopes of the race--that myopic, hypermetropic and astigmatic eyes were not in existence? Such a conclusion would be manifestly unfair. It seems impossible, in this view, to make any fair comparison of the health of women in the present, and in the past; that is, any comparison which will be sufficiently accurate for scientific purposes. It were better, if we must have an idyllic realm somewhere, to posit it rather in the future than in the past, and to work with all the light we are able to secure towards its attainment. This working may, however, be done in two ways as regards education: we may state, first, and I think without fear of contradiction, that there is too much sickness among American women. We may then patiently and fully investigate all the habits of those women, and if we come to the conclusion that co-education or that over-study in amount or in manner is the chief cause, we shall all give it up. We shall then seek and find some better way of securing for our girls an opportunity for the full development of every part of their organization, venturing, however, to add 'brain' to Dr. Clarke's list of "muscle, ovary, stomach, and nerve."[56] Secondly, we may assume in the first place the general statement that co-education is not desirable--is objectionable--that it must inevitably cause sickness if girls study regularly every day; and conclude that regular study is the chief cause of sickness among them. And yet God is his own interpreter, and he will make it plain at last, so that the man who runs may read, that he is no such bungler in his workmanship as to fashion the organism of a woman without giving her at the same time the corresponding strength. We have too much belief in him to believe that the power given to us is in such niggardly measure for our needs; that, in order to carry out perfectly the work of the organs most peculiarly our own, the regular action of the brain must be suspended. Not so. He who fits the shoulder to the burden; who, in planning the complex organism, not only made possible greatly increased size and strength whenever they should be needed, but even took thought also to provide for the return of the blood through capillary and vein from the artery which has been severed by the surgeon's knife, is not so forgetful of ends and means. If extra work is to be done by the organism of the woman, extra strength in exact proportion to the extra effort has been provided, "Where there is power to do That which is willed."
