The Presbyterians the coming year will follow with a laboratory at Princeton. Psychology is no longer feared by religion, but is accepted, though in places yet too timidly, as a source of its further and unending revelation. [Illustration: PRESIDENT G. STANLEY HALL, FOUNDER OF FIRST PSYCHOLOGICAL LABORATORY IN AMERICA.] But psychology is coming close to affairs of church and state in more than one way. One of the greatest crimes of modern society is its conception of criminal jurisprudence. Between the foetal period and adult life man passes through, in abridged series, all the degrees of evolution that have led up through the lower animal stages to his own. In early infancy, and even in childhood, he is not yet wholly man; not yet safely over the brute period of his lineal development. If the domestic calf and chicken spend their first days wild in the woods, this pre-domestic environment will seize upon and develop their pre-domestic traits; and these once set, no amount of domestic training will, thereafter, make calf or chicken anything else than a wild, untamable creature. The early instinctive periods of man's progeny are more prolonged, more delicate, and more susceptible than those of lower animals, yet are of the same nature. If left to evil environment in early years the latent brute within him will surely lay hold of its own, and ripen the yet innocent child to a creature bearing the same relation to the moral and civilized man that the wild wolf does to the house-dog. On the other hand, the wolf whose first lair is the hunter's hearth, grows to share it lovingly with the hunter's children. The government that ignores the hordes of children which crowd to-day the criminal quarters of its great cities, and abandons them to ripen their pre-civilized propensities under such evil influences, becomes itself the foster-father of its own crimes; nurses its own children to fill its poorhouses, and raises its own youths to fill its prisons. Psychology, if on mere ground of financial economy alone, will yet force criminal jurisprudence to begin its work before, rather than after, this early period of "unalterable penalty."

The nervous activities are the regulating activities of every part of the body; and the brain embodies an ever-meddling three-fourths of the body's whole neural energy. The mind is a play-house wherein the skilful physician now looks to observe the condition of the general system, and with growing precision even to read the working of such specific organs as the heart, the stomach, the bladder, and the liver.
