Essays on Educational Reformers. By R. H. Quick, M. A. Cincinnati: Robert Clarke & Co. 328 pp., 12mo. Price, $2.00.

This is a review of the principal educational doctrines, beginning with the once famous schools of the Jesuits, and ending with Herbert Spencer. The main features of each doctrine are given and commented on in a liberal tone. The author differs from Mr. Spencer in some important points, such as the worthlessness of ordinary history, the value of the sciences, and the position fine arts and belles-lettres should occupy in education. In the two concluding chapters he gives his own views on secular education and moral and religious training. Outlines of the lives of the earlier Reformers are given in connection with the discussion of their doctrines. The work possesses value as a history of modern education.

Rumford's Discoveries in Thermodynamics. —In his sketch of the growth of the science of thermodynamics, Prof. P. G. Tait, of the University of Edinburgh, rates the services of Count Rumford second in importance to those of Davy, and does not apparently consider them comparable to those of Joule. Prof. R. H. Thurston, of the Stevens Institute of Technology, in a note relating to Rumford's determination of the mechanical equivalent of heat, points out the injustice of this proceeding, on the part of Prof. Tait, and says that we may claim for Rumford: 1. That he was the first to prove the immateriality of heat, and to indicate that it is a form of energy, publishing his conclusions a year before Davy; 2. That he first, and nearly a half-century before Joule, determined, with almost perfect accuracy, the mechanical equivalent of
