1. THE WISDOM OF LIFE: Being the First Part of ARTHUR SCHO PENHAUER'S Aphorismen zur Lebensweisheit. Translated, with a Preface, by T. BAILEY SAUNDERS, M.A. Second Edition.
" Schopenhauer is not simply a moralist writing in his study and applying abstract principles to the conduct of thought and action, but is also in a large measure a man of the world, with a firm grasp of the actual. The essentially practical character of his ' Wisdom of Life ' is evidenced by his frequent recourse to illustrations, and his singularly apt use of them...Mr. Bailey Saunders' introductory essay adds much to the value and interest of a singularly suggestive volume." — Manchester Examiner.
2. COUNSELS AND MAXIMS: Being the Second Part of ARTHUR SCHOPENHAUER'S Aphorismen zur Lebensiveisheit. Translated by T. BAILEY SAUNDERS, M.A. Second Edition.

THE LAW OF CIVILIZATION AND DECAY.
AN ESSAY ON HISTORY.
BY BROOKS ADAMS.
" A work of great dignity and erudition, showing rare familiarity with the data of history, theology and economics." — Philadelphia Evening Bulletin.
" This is a remarkable essay. It is remarkable alike for its researches and its deductions, and none will fail to be impressed by them. Surprisingly full of penetration and illumination, and we do not hesitate to rank it in the class which is headed by Montesquieu." — A'eio Vork Sun.
" The author has a simple and strong manner of stating facts and drawing conclusions, and his fascinating style makes the book very entertaining." - Boston Home Journal.
"It is particularly brilliant in its generalization concerning the modern employments of the race energy that once made war a profession and a neces sity." — Lincoln Evening News.
"The argument is interesting and even stimulating — the book is well written." — Providence Journal.
THE MACMILLAN COMPANY, 66 FIFTH AVENUE, NEW YORK.

PAIN, PLEASURE, AND ESTHETICS.
KY HENRY RUTGERS MARSHALL.
" Mr. Marshall has long been known as an original thinker in the field which he lias chosen for interpretation; so that this volume which he now presents, and which has been looked for for some time, deserves the best attention, not alone of Simon-pure psychologists, but of physicians, and especi ally neurologists." — Journal of Nervous and Alcntal Disease.
" There can be no question as to the acuteness, the research, and the philo sophical grasp of this writer. No subsequent worker in this field can afford to disregard what has been brought out in this book; and even if some of the author's views shall be shown to require modification, his treatise will remain an admirable example of what a scientific work should be." — The Independent.
" It may well be said that Mr. Marshall's essay is the most successful of all yet published attempts to conceive our pleasures and displeasures urtder some thing like a single point of view...Acquaintance with Mr. Marshall's work will be indispensable to every future student of the subject. The book is almost ' epoch-making ' in the present situation of science." — '1'he Nation.
