The Natural History of Digestion. 



BY A. LOCKHART GILLESPIE, 



M.D., F.R.C.P. ED., F.R.S. ED. 



Dr. Gillespie, who has long been known as an original investigator in 

 this department of physiology, has in the present volume attempted to 

 bring together all the facts and recent discoveries bearing on this subject 

 of great scientific and practical importance. Dealing with the subject in 

 much detail, as well as broadly and comprehensively, the book appeals 

 both to medical specialist and general reader. The author shows that 

 digestion is a process which occurs throughout animated nature, and 

 beginning with digestion in plants, and describing many original and 

 other experiments with carnivorous plants, he passes on to digestion in 

 the lower animals, and then deals fully with the many complicated prob- 

 lems offered by digestion in the higher animals and man. The practical 

 questions of diet are examined in their various aspects, and the influence 

 of alcohol, tea, and other stimulants discussed.

Degeneracy : 



ITS CAUSES, SIGNS, AND RESULTS. 



BY PROFESSOR EUGENE S. TALBOT, M.D., Chicago. 



This volume presents, in a simple and comprehensive way, the basis of 

 fact on which the speculations of Nordau and others have been founded. 

 It is the first book written in English by a competent authority dealing 

 broadly with this subject. The author deals with more especial fulness 

 with the signs of degeneracy in the head and face ears, jaws, teeth, etc. 

 as those which he has chiefly studied, and which are of most general 

 interest ; but he also discusses degeneracy in the body generally, as well 

 as its mental forms. The chief causes tending to produce degeneracy in 

 modern life are discussed heredity, climate, foods, alcohol, education, 

 etc. and the methods of combating them considered. The book is fully 

 illustrated, chiefly from original photographs.
