A COURSE OF ELEMENTARY MATHEMATICS, FOR THE USE OF CANDIDATES FOR ADMISSION INTO EITHER OF THE MILITARY COLLEGES; OF APPLICANTS FOR APPOINTMENTS IN THE HOME OR INDIAN CIVIL SERVICE; AND OF MATHEMATICAL STUDENTS GENERALLY. BY PROFESSOR J. R. YOUNG. In One closely-printed Volume, 8vo, pp. 648, price 12s. ATHENÆUM, _March_ 9, 1861.--"In the work before us he has digested a complete Elementary Course by aid of his long experience as a teacher and a writer; and he has produced a very useful book.... Mr. Young has not allowed his own taste to rule the distribution, but has adjusted his parts with the skill of a veteran." THE LONDON REVIEW, _April_ 6, 1861.--"Mr. Young is well known as the author of undoubtedly the best treatise on the 'Theory of Equations' which is to be found in our language--a treatise distinguished by originality of thought, great learning, and admirable perspicuity. Nor are these qualities wanting in the work which we are reviewing.... Considering the difficulty of the task which Mr. Young has undertaken to discharge, and the extent of useful knowledge he has succeeded in imparting accurately and lucidly in so small a compass, we can without hesitation commend this work to the public as by far the best elementary course of mathematics in our language."

WITH FORTY-ONE ILLUSTRATIONS. In fcap. 4to, cloth. OBSERVER, _Jan._ 3, 1864.--"This book should be studied by all who have a grain of kindly feeling towards their poorer neighbours, and every one should strive to find some means of alleviating the misery it points out. The illustrations with which the book is liberally supplied will go far to make the subject better understood." BELL'S MESSENGER, _Jan._ 16, 1864.--"'Another Blow for Life' is a great and good book, and does honour to its author's head and heart."
