A TREATISE ON ELEMENTARY DYNAMICS. Crown 8vo. Second Edition, Reprinted. 7s. 6d.

The Athenæum 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.

FOR

Nature says: -The same high standard of excellence is maintained and the author must again be congratulated on his efforts to place in the hands of a beginner a book which will give him correct ideas of the laws and principles which are included in a study of mechanics....If the reader should fail to understand the chapter on the laws of motion, he must attribute it either to his want of ability or the nature of the subject, for we fail to see how the author could improve his remarks on this part of the subject.
