posed to have a sound knowledge of ordinary geometry and a moderate acquaintance with the elements of algebra and trigonometry." The author adds in his preface, but he (the student) "is also supposed to have—what he can easily obtain from the simple parts of the first two chapters of Thompson & Tait's 'Elements of Natural Philosophy,' or from Clerk Maxwell's excellent little treatise on 'Matter and Motion' a general acquaintance with the fundamental principles of kinematics of a point and of kinetics of a particle." It was the author's intention to complete his series of text-books by similar volumes on "Dynamics," "Sound," and "Electricity."
Theory and Practice of Teaching. By Rev. Edward Turing. New and revised edition. Cambridge: University Press. Pp. 262. Price, $1.
We noticed the first edition of this spirited book at the time of its appearance. It is very readable, but full of English views upon the subject, although many of them are as applicable here as anywhere. We are glad to see that it has been amplified and improved.
