through any cause, this fine equipoise is disturbed, or lost, then a way is opened for the influx of more subtle evil influences than such as invade the body, because they have power to act upon the reason and the passions, obscuring the one and inflaming the others. MENTAL DISTURBANCES. We know how surely the loss of bodily health results in mental disturbance. If the seat of disease be remote from the brain, the disturbance is usually slight; but it increases as the trouble comes nearer and nearer to that organ, and shows itself in multiform ways according to character, temperament or inherited disposition; but almost always in a predominance of what is evil instead of good. There will be fretfulness, or ill-nature, or selfish exactions, or mental obscurity, or unreasoning demands, or, it may be, vicious and cruel propensities, where, when the brain was undisturbed by disease, reason held rule with patience and loving kindness. If the disease which has attacked the brain goes on increasing, the mental disease which follows as a consequence of organic disturbance or deterioration, will have increased also, until insanity may be established in some one or more of its many sad and varied forms. INSANITY. It is, therefore, a very serious thing for a man to take into his body any substance which, on reaching that wonderfully delicate organ--the brain, sets up therein a diseased action; for, diseased mental action is sure to follow, and there is only one true name for mental disease, and that is _insanity_. A fever is a fever, whether it be light or intensely burning; and so any disturbance of the mind's rational equipoise is insanity, whether it be in the simplest form of temporary obscurity, or in the midnight of a totally darkened intellect. We are not writing in the interest of any special theory, nor in the spirit of partisanship; but with an earnest desire to make the truth appear. The reader must not accept anything simply because we say it, but because he sees it to be true. Now, as to this matter of insanity, let him think calmly. The word is one that gives us a shock; and, as we hear it, we almost involuntarily thank God for the good gift of a well-balanced mind. What, if from any cause this beautiful equipoise should be disturbed and the mind lose its power to think clearly, or to hold the lower passions in due control? Shall we exceed the truth if we say that the man in whom this takes place is insane just in the degree that he has lost his rational self-control; and that he is restored when he regains that control? In this view, the question as to the hurtfulness of alcoholic drinks assumes a new and graver aspect. Do they disturb the brain when they come in contact with its substance; and deteriorate it if the contact be
