POPULAR SCIENCE MONTHLY.

generation. Experience shows that it is comparatively easy to ascertain what marriages, generally speaking, are prone to result in obviously vitiated progeny; or if not in these, then, to some extent at least, in the progeny which, being unnaturally constituted, are prone to develop their weaker strands of personality, and so to break down in the end. But to this course neither prudery nor superstition nor selfishness will ever assent; it must be pursued in spite of these, and by the only method which science now recognizes—namely, accurate observation, careful record, and the most comprehensive, skillful comparison, all in order that truthful inductions may be finally secured. That parents should train up their children to look forward to marriage not as the acme of personal indulgence and satisfaction, but as a most responsible partnership for the developmental keeping of unborn fortunes, and the proper nurturing of the children that may come to them, is no longer speculation, but a science-founded fact. Undoubtedly the highest state of adult satisfaction will always be closely associated with what may be characterized as child completion. Moreover, that an educational system which so thoroughly ignores this most important of all educational subjects must, in time, be subjected to the criticism which science may justly develop, is amply borne out by the cases studied. Often, indeed, has it appeared that had a modicum of real knowledge been at hand, most disastrous results would naturally have been obviated. Educators lead the day; why not they lead in directions which shall most truly correct the results of physiological ignorance and daring? That no man or woman should go forth from college with such vital knowledge unlearned is probably the first and most important means of preventing incurable insanity conceivable; and that these in turn should never hesitate to diffuse popularly that which they have been so favored in the learning, implies a duty which the intelligence itself makes clear.

So, too, if persistent overstrain and exhaustion of parents, either prospective or actual, leads directly to starvation of their own structural elements, how probable that the initiating and bearing and nurturing of children is to a like extent detrimentally interfered with in any given case through the development of an "erratic cell growth." Certain it is that completeness of development depends on two things—namely, nutrition and exercise. In a biological sense both these are dependent upon a right adjustment of supply to demand. Hence starvation or engorgement, inactivity or overwork, each may lead to the same dynamic result—that is to say, to an interference with the proper growth of the organism. That due heed, then, should always be given to the necessary health preservation of those who essay to become parents, not only in preparation for but during the whole
