The bearing of these figures will perhaps be realized by comparing them with similar figures regarding Cornell University, which is largely a technical school, since nearly one half of its students pursue technical courses similar to those in the Institute. In 1898 the total income of that university was $583,000, of which about $121,000, or only 20 per cent, was received from tuition fees. Its invested funds amounted to $6,446,818. The State has generously given aid to the Institute in some of its most trying times; as in 1888, when it gave $200,000, one half unconditionally and the other half for the support of free scholarships; and again in 1895, when it granted unconditionally $25,000 a year for six years and $2,000 a year additional for scholarships. Although the school has a very inadequate endowment, yet the future looks bright. It is significant of the general appreciation of its work that men and women who have not received a technical education have devoted a large part of their fortunes to providing such education for others. Among the recent benefactors of the Institute we may name Henry L. Pierce, John W. Randall, Mrs. Julia B. Huntington James and Edward Austin, who, within less than three years have bequeathed nearly a million and a half dollars to the school. If the large gifts of recent years are continued, the school will before long be put financially upon a level with its neighbors. May we not hope that as the applications of science to the arts enrich the alumni and friends of the Institute, they may help to make the road easy for their successors by devoting a part of their riches to the advancement of technical education? THE PSYCHOLOGY OF CRAZES. BY PROFESSOR G. T. W. PATRICK, UNIVERSITY OF IOWA. A well-known Washington newspaper correspondent, writing of the recent Congress of the Daughters of the American Revolution and its disorderly meetings, says: “It is the unanimous opinion of those who have attended the congress that, while the Daughters of the American Revolution, individually, are nearly all intellectual, refined and attractive women, collectively they are an uncontrollable mob.” Why is the social conduct of human beings different from their conduct as individuals? This is the problem of the new science of social psychology. The following study of crazes and epidemics is offered as a slight contribution to this science.
