Differential and Integral Calculus. By A. G. Greenhill, M.A. (Mac-

millan.)—This is an effort by a teacher of experience to give an elementary knowledge of the use of the calculus to students, who require it for practical purposes ; such, for instance, as those whom the author has to do with in his capacity of teacher at Woolwich. Professor Greenhill's volume will doubtless do something as a guide. He has consulted and utilised a considerable number of predecessors, the subject having been frequently treated during the last twenty-five years. Among these, however, we do not observe the names of Professors Price, Boole, or De Morgan.—An elementary hook on the same subject is An Introduction to the Differential and Integral Calculus. By W. J. Millar, M.A. (Blackie and Son.)
