In preparing this work the author's object has been to include in it such portions of Theoretical Mechanics as can be conveniently investigated without the use of the Differential Calculus, and so render it suitable as a manual for the junior classes in the University and the higher classes in Schools, With one or two short exceptions, the student is not presumed to require a knowledge of any branches of Mathematics beyond the elements ''of Algebra, Geometry, and Trigonometry. Several additional propositions'' have been incorporated in the work for the purpose of rendering it more complete; and the collection of Examples and Problems has been largely increased.

A collection of examples and problems has been appended to this work, which are sufficiently numerous and varied in character to afford useful ''exercise for the student. For the greater part of them, recourse has been'' had to the Examination Papers set in the University and the several Colleges during the last twenty years.

This edition has been carefully revised throughout, and many new illustrations and examples added, which it is hoped will increase its ''usefulness to students at the Universities and in Schools. In accordance'' with suggestions from many engaged in tuition, answers to all the Examples have been given at the end of the book.
