MIND IN THE LOWER ANIMALS IN HEALTH AND DISEASE. 
By W. Lauper Linpsay, M. D., F. R.S. E., etc. 2 vols., Svo. Cloth, $4.00. 
‘“*The author of this work, which, regarded merely as an accumulation of 
verified and classified facts, is a unique and precious contribution to the data of 
comparative psychology, claims that he entered on his inquiry without any theory 
to defend, support, or illustrate. We are bound to say that, while his general 
conclusions are boldly and continually avowed, his claim of fairness and caution 
is justified by his method of examining particular phenomena ; that he seems 
willing at all times to renounce any impression or belief which is shown to be 
scientifically untenable.”—New York Sun. 
“Tn this work—two volumes of over 500 pages—Dr. Lindsay marshals a pro- 
portionately large number of facts against those philosophers who maintain that 
the intelligence of man differs in kind and not simply in degree from tbat of the 
lower avimals. It is one purpose of his book to show that the main differences 
between man and the lower animals exist ratherin their physical than in their 
Mental structure. In this way of Pree all animals possess not the semblance 
of, but the troe substance of mind and will."—New York World. 
“So faras we are aware there has been no treatise upon the subject of animal 
intelligence so broad in its foundations, so well considered, or so scientific iv its 
methods of in uiry, as that which bas been prepared by Dr. W. Lauder Lindsay 
in two large volumes, the first being devoted to a study of animal mind in health, 
and the second to animal mind in disease, We may Safely say that his werk is, 
in some respects, the most important essay of the kind that has yet been under- 
taken. His observations have been supplemented by a thorough mastery of the 
history and literature of the subject, and hence his conclusions rest upon the 
broadest possible foundation of safe induction. There is a good analytical index 
ee book, as there ought to be to every work of the kind."—New York Evening

A GLOSSARY OF BIOLOGICAL, ANATOMICAL, AND PHYSIO- 
LOGICAL TERMS. By Tuomas Dunman. Small 8vo, Cloth. 161 
pages. Price, $1.00. 
“It has been the author's task to furnish here a small and convenient but very 
complete glossary of those terms ; and he has done this so well, both in his choice 
of terms for definition and in his clear exposition of their etymological and tech- 
nical meaning, as to leave nothing to be desired in this direction."—New York
