Experimental studies relating to ship beri-beri and scurvy, A. Holst 

 (Jour. Ittnj. [('(iitibridi/c], 7 {1H07), No. '>, pp. 61U-63S). — Experiments on the 

 effect of feedinjr single foods, undertaken with pigeons and chickens, showed 

 that if long continued such rations caused degenerative changes. For instance, 

 long continued feeding of cooked meat or coarsely ground Indian corn as an 

 e.xclusive diet caused polyneuritis in chickens. (Jeneral conclusions were not 

 drawn and the work was continued with mannnals. 



Experimental studies relating to ship beri-beri and scurvy, A. Holst and 

 T. Fr(""ilicii {Joitr. Hiju. \r<unhri<hje], 7 (1007). Xo. 5, pp. 6'J.'/-6"77, pis. 2).— The 

 experiments which were made with guinea pigs showed that a one-sided diet 

 (grain, groats, bread, or dried potatoes) produced a disease that closely cor- 

 responded to human scurvy. A one-sided died of fresh cabbage or fresh pota- 

 toes did not produce this disease. It was further observed that the disease was 

 favorably influenced by different foods which are commonly classed as antiscor- 

 butics. It was found that cabbage which was boiled for half an hour at 110° C. 

 lost a considerable part, though not all, of its protective power. 



The effects of cooking food ui»on the health of animals were taken into ac- 

 count in a number of the exi)eriments. The authors have not been able to 

 explain '" in an unmistakable way, why the one-sided diets, . . . produce 

 scurvy." 



Metabolism and practical medicine, C. von Noorden (Chicago. 1907, vols. 1, 

 pp. A' 17 +',52; 2, pp. XV 1+525; 3, pp. X X +527-1 320). —Yolume I, entitled 

 The Physiology of Metabolism, is edited by A. Magnus-Levy and contains dis- 

 cussions by different authors on such fundamental subjects as digestion and 

 absorption, fate of food stuffs in the tissues, metabolism in man, influence of 

 muscular work on metabolism, and metabolism in old age. 



Volumes It and III are each entitled The Pathology of Metabolism, by C. von 

 Noorden et al. The former contains summaries by different authors on metab- 

 olism in hunger, in chronic starvation and overfeeding, and in different dis- 

 eases, and summarizes and discusses the pathology of metabolism and consti- 

 tutes an extensive study and discussion of available data on the pathology of 

 metabolism. The latter is an extended summary and discussion of available 

 data on diet in relation to diabetes mellitus, gout, obesity, diseases of the skin 

 and other diseases, and the effect of mineral waters, baths, drugs and poisons, 

 light and lioentgen and radium rays upon metabolism. 



The bibliographical summaries which accompany tlie different sections are 

 important features and the work as a whole constitutes an extended summary 

 of available data on the subjects included. The English edition is edited by 

 I. W. Hall. 



The common bacterial infections of the digestive tract, C. A. Hebter (Xeio 

 York and London, 11)07. pp. X1I+3H0). — In this volume, which is largely a 

 medical treatise summarizing the author's investigations and other data on 

 bacterial infection of the digestive tract as a cause of disease, the author has 

 discussed the effect of contaminated food on public health and related (]uestions 

 and summarized much data of interest in relation to dietetics. 



Studies of the elementary composition of liver, W. Profitlich (Arch. 

 Physiol. [Pfliif/rr], IID (1007), Xo. 9-11, pp. y/«.5-.'/<S2).— Dried beef liver, freed 

 from fat, ash, and glycogen, contained practically the same amount of nitrogen 

 as liver from a well fed dog. Considerable variations were noted in the carbon 

 and hydrogen content of both sorts of liver.
