matter and diet lists have been prepared and other changes made. These and 

 other matters are discussed at some length in the preface to this edition. 



The child — its care, diet, and common ills, E. M. Sell (New York, 191$, pp. 

 VIII-\-207, figs. S4). — A brief but fairly complete guide in the intelligent care 

 of infants and small children. The 40 or more pages devoted to feeding out- 

 line the general principles regarding the diet of children and give definite 

 practical suggestions as to their application. The relation of diet to the more 

 common disorders of childhood is also noted. 



The proper diet in the Tropics, with some pertinent remarks on the use 

 of alcohol, A. C. Eustis (Amer. Jour. Trop. Diseases and Prev. Med., 1 (1918), 

 No. 4, pp. 288-293). — The author holds that there is greater danger from an 

 excessive use of meat in tropical than in temperate regions, because "pto- 

 maines ", which may be produced from undigested meat by the action of putre- 

 factive bacteria in the colon, and which under ordinary conditions would be 

 " rendered inert by the liver cells ", would not, in his opinion, be so taken care 

 of where there is little severe exercise, as is the case with most residents in 

 warm regions. 



He believes further that in such r^ons " there is little need of internal com- 

 bustion to maintain the body temperature." 



Similar arguments are given against the use of alcohol. 



In the author's opinion, not more than 40 gm. of protein per day should be 

 eaten in the Tropics. He believes that the energy value of the daily diet should 

 be from 2,000 to 2,500 calories, depending upon the muscular work done, fats 

 being taken in moderation and the energy supplied largely from carbohydrates ; 

 that vegetable proteids are preferable to animal proteids; and that the diet 

 should contain an abundance of fruits and vegetables. 



The desirability of limiting the amount of meat in the diet is illustrated by 

 a case cited in which symptoms of toxemia in a patient were overcome by re- 

 ducing the meat consumption and which the author considers typical of many 

 which he states have come under his observation. 



Meat feeding experiments with mice and their value as a means of deter- 

 mining the harmfulness of suspected meat upon the health, R. Reinhaedt 

 and E. Seibold (Ztschr. Infektionskrank. u. Eyg. Haustiere, 12 {1912), No. 4, 

 pp. 832-350). — The literature relating to feeding experiments vnth diseased 

 meats is reviewed and the results are given of a series of experiments in which 

 white mice were fed upon meat which had been infected in some instances 

 with Bacillus paratyphosus and in others with B. enteriditis, the infections hav^ 

 ing undergone various stages of development. 



From the results of these experiments, the authors conclude that white mice 

 are not suitable subjects for such experiments and that neither positive nor 

 negative results of the feeding of suspected meat to white mice will permit the 

 drawing of conclusions relative to the fitaiess for human food of the meat in 

 question. 



Creatin and creatinin in total and partial fasting, V. Scaffidi (Arch. Ital. 

 Biol., 59 (1913), No. 2, pp. 161-172). — Studies were made of creatin and creatinin 

 and of total nitrogen exchange in feeding laboratory animals (dogs) on a 

 mixed diet, in total fasting, and in a diet in which the nitrogen was replaced 

 by fats. 



During fasting a variable quantity of creatin appeared in the urine, while 

 under normal conditions of nitrogen equilibrium little or none was found. The 

 quantity of nitrogen eliminated in these experiments and derived from the 

 combustion of tissue was greater than that eliminated during maintenance upon 

 a mixed diet sufficient to maintain body weight. More creatinin was elimi-
