THE PRINCIPLES OF MENTAL PHYSIOLOGY. With their Ap- 

 plications to the Training and Discipline of the Mind, and the Study of its 

 Morbid Conditions. By W. B. Carpenter, F. R. S., etc. Illustrated, nmo. 

 737 pages. Price, $3.00. 

 " The work is probably the ablest exposition of the subject which has been given to the world, and goes 

 far to establish a new system of Mental Philosophy, upon a much broader and more substantial basis than 

 it has heretofore stood." — St. Louis Democrat. 



" Let us add that nothing we have said, or in any limited space could say, would give an adequate con- 

 ception of the valuable and curious collection of facts bearing on morbid mental conditions, the learned 

 physiological exposition, and the treasure-house of useful hints for mental training, which make this large 

 and yet very amusing, as well as instructive book, an encyclopaedia of well-classified and often very 

 startling psychological experiences." — London Spectator. 



THE EXPANSE OF HEAVEN. A Series of Essays on the Wonders of 

 the Firmament. By R. A. Proctor, B. A. 



" A very charming work ; cannot fail to lift the reader's mind up ' through Nature's work to Nature's 

 God.' " — London Standard. 



" Prof. R. A. Proctor is one of the very few rhetorical scientists who have the art of making science 

 popular without making it or themselves contemptible. It will be hard to find anywhere else so much 

 skill in effective expression, combined with so much genuine astronomical learning, as is to be seen in his 

 new volume." — Christian Union. 



PHYSIOLOGY FOR PRACTICAL USE. By various Writers. Edited 

 by James Hinton. With 50 Illustrations. 1 vol., i2mo. Price, $2.25. 



" This book is one of rare value, and will prove useful to a large class in the community. Its chief 

 recommendation is in its applying the laws of the science of physiology to cases of the deranged or diseased 

 operations of the organs or processes of the human system. It is as thoroughly practical as is a book of 

 formulas of medicine, and the style in which the information is given is so entirely devoid of the mystification 

 of technical or scientific terms that the most simple can easily comprehend it." — Boston Gazette. 



" Of all the works upon health of a popular character which we have met with for some time, and we 

 are glad to think that this most important branch of knowledge is becoming more enlarged every day, 

 the work before us appears to be the simplest, the soundest, and the best." — Chicago Inter-Ocean. 



THE GREAT ICE AGE, and its Relations to the Antiquity of 



Man. By James Geikie, F. R. S. E. With Maps, Charts, and numerous Illus- 

 trations. 1 vol., thick i2mo. Price, $2.50. 

 " * The Great Ice Age ' is a work of extraordinary interest and value. The subject is peculiarly 

 attractive in the immensity of its scope, and exercises a fascination over the imagination so absorbing that 

 it can scarcely find expression in words. It has all the charms of wonder-tales, and excites scientific and 

 unscientific minds alike." — Boston Gazette. 



u Every step in the process is traced with admirable perspicuity and fullness by Mr. Geikie." — Lon- 

 don Saturday Review. 



" ' The Great Ice Age,' by James Geikie, is a book that unites the popular and abstruse elements of 

 scientific research to a remarkable degree. The author recounts a story that is more romantic than nine 

 novels out of ten, and we have read the book from first to last with unflagging interest." — Boston Gammer*, 

 cial Bulletin.

 vised, with additions, by the author, since the delivery. i2mo. 120 pages.

 tions and corrections not in the newspaper reports. 



THE PHYSIOLOGY OF MAN. Designed to represent the Existing State 

 of Physiological Science as applied to the Functions of the Human Body. By 

 Austin Flint, Jr., M. D. Complete in Five Volumes, octavo, of about 500 

 pages each, with 105 Illustrations. Cloth, $22.00; sheep, $27.00. Each vol- 

 ume sold separately. Price, cloth, $4.50; sheep, $5.50. The fifth and last 

 volume has just been issued. 

 The above is by far the most complete work on human physiology in the English language. It treats 

 of the functions of the human body from a practical point of view, and is enriched by many original ex- 

 periments and observations by the author. Considerable space is given to physiological anatomy, par- 

 ticularly the structure of glandular organs, the digestive system, nervous system, blood-vessels, organs of 

 special sense, and organs of generation. It not only considers the various functions of the body, from an 

 experimental stand-point, but is peculiarly rich in citations of the literature of physiology. It is therefore 

 invaluable as a work of reference for those who wish to study the subject of physiology exhaustively. As 

 a complete treatise on a subject of such interest, it should be in the libraries of literary and scientific men, 

 as well as in the hands of practitioners and students of medicine. Illustrations are introduced wherever 

 they are necessary for the elucidation of the text.
