Rh have come across the result of some big educational blunder, owing either to the system in vogue or else to those who execute it." (See Steps toward Insanity, New York Medical Journal, August 14, 1897.)

There is one fact about heredity which seems not to be commonly considered—namely, that each individual is really the descendant of not only his immediate parents, but of the two lines of ancestry indefinitely far back and widespread. Thus, in many instances, the dominating characteristics are not those of father and mother, but of grandparents, or of some other antecedent or collateral relatives instead. In fact, each individual in its development from the germ to adulthood passes through not only many animal forms, but through many ancestral phases of character as well. And, as in the first case, the size and strength of adult physical features depend on the stage at which growth becomes abnormally extended, perverted, or arrested, so, with regard to mental and moral qualities and their persistence under stress, the outcome mostly if not entirely depends upon the extent to which they are allowed or constrained to develop, or the reverse. Here we often see the absolutely limiting influence of "atavism," or what is characterized as "reversion," to generations further removed than the parental, but which really is the result of an exaggeration or a stoppage, or a perversion of development before the stage of parental dominance is finally reached. In this way the featural and mental characteristics of relatives as far removed as great-grand-parents or great-granduncles, as well as grandparents and uncles, are seen to appear in children even when young, to be finally either accentuated and made prominent, or else possibly outgrown or otherwise overcome as the years go by, and as the later parental determining powers and the corresponding environment come to manifest their influence.

With this view of heredity in mind, it is easy to see how the real basis of every mental breakdown may be and probably is simply an overdoing or perversion or other irregularity at some premature or "atavistic" stage of development; and that anything and everything which may have had to do in causing this should be considered as a primary step toward the insanity itself. But easy as it is to see this theoretically, it does not necessarily follow that it is easy to get hold of the real facts or to help the matter in any given case. Many times families are loath to reveal things which might indicate such a basis of the dreaded disease. Many times they do not recognize the necessity of telling what they would otherwise be willing enough to reveal. Many things are absolutely forgotten or have been at best only vaguely comprehended. Sometimes conscious deception is practiced; at others, the party who really has known the facts is dead or is otherwise inaccessible. But more often, and more interfering still, is the
