had some sudden shock, some severe domestic trial, some long strain, or that it is the outcome of acute illness or of one of the forms of chronic disturbance of nutrition which result in what we now call general neurasthenia or nervous weakness,--a condition which has a most varied parentage. With the ultimate medical causation of these disorderly states of body I do not mean to concern myself here, except to add also that the great physiological revolutions of a woman's life are often responsible for the physical failures which create nervousness. If she is at the worst she becomes a ready victim of hysteria. The emotions so easily called into activity give rise to tears. Too weak for wholesome restraint, she yields. The little convulsive act we call crying brings uncontrollable, or what seems to her to be uncontrollable, twitching of the face. The jaw and hands get rigid, and she has a hysterical convulsion, and is on the way to worse perils. The intelligent despotism of self-control is at an end, and every new attack upon its normal prerogatives leaves her less and less able to resist. Let us return to the causes of this sad condition. It is a common mistake to suppose that the well and strong are not liable to onsets which cause nervousness. As a rule, they rarely suffer; but we are neatly ballasted, and some well people are nearer to the chance of being so overturned than it is pleasant to believe. Thus it is that what for lack of a better name we call "shock" is at times and in some people capable of inflicting very lasting evil in the way of nervousness.
