By the same Author. A TREATISE ON ELEMENTARY DYNAMICS. Crown 8vo. 78. 6d. The Athenaeum says:-This is one of the best and most complete treatises on elementary dynamics which have come before us for a long time. The principles of the subject are stated with great clearness, and the illustrative examples are very appropriate. We have been particularly struck with the manner in which the author combines perspicuity with brevity in his short chapter on " units and dimensions," a subject which, though apparently very simple, often presents considerable difficulties to a beginner. Special praise is also due to his chapter on the "hodograph" and "normal accelerations." The Cambridge Review says:-Mr Loney may be congratulated on the production of a most valuable text book, at once simple and complete. The earlier chapters on uniformly accelerated motion and the laws of motion are treated with extreme simplicity....A chapter of wrought-out examples clears up many difficulties which the beginner experiences in tackling problems, but which could scarcely be explained in the text. We are glad to see that the method of the hodograph is used in treating of normal acceleration, and that cycloidal motion is considered as a case of simple harmonic motion. The Journal of Education says:-... The necessary explanations and proofs are clear and the petty difficulties which perplex a beginner are in no way ignored.... The Educational Times says:-...The manner, if not the method, of many of the proofs is fresh and new; and the hodograph is used effectively in dealing with normal acceleration and the motion of a body in a conic section. So too, in treating of pendulum and cycloidal motion, the introduction of the conception of simple harmonic motion certainly considerably simplifies some of the proofs.... The Scots Observer says:-...He has done really good service in the provision of suitable examples and a great number of capital test exercises. His treatment of the motion of a railway carriage on a curved portion of the railway line is especially well illustrated....His diagrams are first-rate....In one word, a really excellent text-book.
