senescence, aging, decay


The following biographical studies have been made with the purpose of showing through concrete cases some aspects of mental decline in senescence. To the objection that each of these cases follows a course in a degree divergent from that of normal mental decline, the reply is that a study of these striking instanced, we believe, afford a more ready insight into the underlying phenomena than would a similar one which deals with average or typical cases. The significance of exceptional cases should not be underestimated. Certain peculiar conditions have been present which have modified the typical phenomena, but after due allowance has been made for these conditions and their effects, the underlying essential causes stand out more clearly.
