XXXV. THE NATURAL HISTORY OF DIGESTION. 

 By A. LocKHART Gillespie, M.D., F.R.C.P. Ed., 

 F.R.S. Ed. $1.50. 



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 problems 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. 



XXXVI. DEGENERACY: Its Causes, Signs, and Results. 

 By Professor Eugene S. Talbot, M.D., Chicago. $1.50. 



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 com- 

 bating them considered. The book is fully illustrated, chiefly from original 

 photographs.
