FOODS HUMAN NUTEITION. 263 



Concerning- the composition of fruits and berries and the value of chemical 

 analyses in judging marmalade, together with fruit statistics for the year 

 1907, E. Baier and I\ Hasse (Ztschr. Untcrsuch. Nahr. u. Geniissmtl., Jn 

 (n)OS), No. 3, pp. IJfO-l-'fS). — The analyses of fruit and fruit juices reported 

 were made with a view to securing data for the use of food chemists. 



Concerning fruit juices and marmalades for the year 1907, K.- Fischer 

 and K. Alpers (Ztsclir. Uiifcrxiicli. Xdlir. ii. (lonissmtl.. I.', ilDOS), No. 3, pp. 

 Ii'i-I'i7). — A number of analyses of fruit juices and marmalades are reported, 

 which were midertaken to secure data for judging of the quality of fruit 

 products. 



Fruit juice statistics for the year 1907, F. Schwarz and O. Weber (Ztschr. 

 rnlcrauch. Nahr. u. Genussmtl., 15 {1908), No. 3, pp. J//7, i-'/S). — Analyses are 

 reitorted of 14 samples of raspberry juice. 



Concentrated fruit juice, A. Rohrig (Ztschr. Unicrsuch. Nahr. u. GniussmtL, 

 15 (1908), No. 3, j)p. I'i8-152). — Analyses are reported of fruit juices made by 

 a special process in which the aromatic principles are extracted with chloro- 

 form, the remaining juice concentrated, and the aromatic principles again added 

 after freeing from chloroform. 



Hungarian fruit juices, J. Halmi (Ztschr. Untcrsuch. Nahr. u. Genussmtl., 

 15 (1908), No. 3, pp. 153-160). — A large number of analyses are reported and 

 discussed. 



The detail of the enforcement of the Food and Drugs Act, W. D. Bigelow 

 (r. .s'. Dcpt. Agr. Yearbook J907, pp. 321-328). — This paper discusses the admin- 

 istration and application of the Federal Food and Drugs Act of June 30, 1900. 

 The enforcement of the law naturally proceeds along two lines, namely, the 

 inspection of imported foods and drugs, and the inspection of domestic products. 

 Such questious as invoices and certification, procedure, prosecution, and seizure 

 and confiscation of illegal goods are considered. 



" While it is plainly the purpose of the majority of the manufacturers and 

 dealers to comply with the law, and the character of the foods and drugs on the 

 American market has been greatly improved since its enactment, the prosecu- 

 tion of those who seek to evade it will doubtless cau.se still further improve- 

 ment." 



The nutrition of man, R. H. Chittenden (New York, 1907, pp. XII+32t, 

 figs. 29). — In this volume "the attempt has been made to give a systematic 

 account of our knowledge regarding some of the more important processes of 

 nutrition, with special reference to the needs of the body for food." In his dis- 

 cnssions the author has incorporated the results of observations and experi- 

 ments carried on during recent years by himself and his associates, and sum- 

 marized and discussed this and other data, with special reference to modern 

 physiological views. The subjects treated include foods and their digestion, 

 absorption, assimilation and the processes of metabolism, the balance of nutri- 

 tion, the source of energy of muscular work, with some theories of proteld 

 metabolism, dietary habits and true food requirements, further experiments 

 and observations bearing on true food requirements, the effect of low proteid 

 diet on high proteid animals, and practical applications of the theories and 

 deductions presented. 



The autlwtr upholds the position advanced in earlier writings (E. S. R., 16, 

 p. 08.5) that the protein intake may be materially less than the usual dietary 

 standards require, and in his discussion of this qnestion he quotes the results 

 of a numl)er of experiments with dogs on what lie considers a low proteid diet 

 in which the subjects maintained nitrogen equilibrium and body weight, or in 

 some cases made slight gains. For instance, one of the dogs lived for ten
