1916] FOODS — HUMAN NUTRITION. 165 



addition to general information regarding tlie scope of the work, detailed state- 

 ments are made of the inspection of slaugliterhuuses, cold-storage plants, can- 

 ning factories, etc. During the year 6,180 samples of foods and drugs were 

 examined, of which 1G.3 per cent were found to be below the legal standard. 



An extended report is given of the work done in the sanitary inspection of the 

 shelllish industry of the State. 



The use of box rations by the French troops, E. Maubei, {Bui. Acad. Med. 

 [raris], 75 {1916), No. i), pp. 25/f-25l)). — Box rations for army use are suggested 

 which contain a mixture of meat and either fresh or dried vegetables chopped 

 in small pieces. It is intended that each box shall furnish about 30 gm. of 

 protein and 500 calories of energy and that each man shall receive 4 of these 

 boxes, the total weight of which shall not exceed 1 kg. To complete the ration, 

 it is recommended that the men receive 1,200 gm. of bread, 0.5 liter of wine, 

 and 100 gm, of dried fruit (preferably figs) every two days. The total energy 

 value of this ration is 3,000 calories daily. 



The chemistry of cow's milk and other products used in infant feeding, 

 F. W. Howe {ArcJi. Fed., 33 {1016), No. 1, pp. 1-12).— A compilation of data 

 showing the composition of milk as affected by a number of different factors, 

 and also the nature and composition of other products (protein milk, whey, 

 etc.) used in infant feeding. 



The dig'estibility of the proteins of milk and their role in infant nutrition, 

 L. E. Holt {Arch. Fed., 33 {1916), No. 1, pp. 13-19, fig. 1).— The protein need of 

 infants is considered in the light of recent investigations and clinical experience. 

 The author states that " the digestion of the protein of cow's milk is a much 

 easier matter than was formerly supposed ; that while injury may without 

 question be done by high protein feeding, this is very unlikely to occur, unless 

 amounts much in excess of those commonly used in infant feeding are adminis- 

 tered ; that in such amounts we have as yet neither clinical nor laboratory evi- 

 dence to show that protein is harmful ; that although an infant receiving breast- 

 milk takes rather less than 7 per cent of his calories as protein, this can not be 

 taken as an exact criterion of how much protein should be administered when 

 cow's milk is the food ; [and] that the deficiency of cow's milk casein in certain 

 essential amino acids may be made up by giving an excess of this protein." 



Present opinion as to the role of fat in infant feeding, J. L. Mokse {Arch. 

 Fed., 33 {1916), No. 1, pp. 20-24).— A. summary and digest of data. 



A brief resume of the role of carbohydrates in infant feeding, H. R. Mix- 

 sell {Arch. Fed., 33 {1916), No. 1, pp. 31-36). — A summary and digest of data. 



The role of salts in infant feeding, F. H. Baktlett {Arch. Fed., 33 {1916), 

 No. 1, pp. 25-30). — This lecture brings together the results of recent investiga- 

 tions of mineral elements in infant metabolism. Especial attention is given to 

 their relation to the low iron content of cow's and woman's milk ; to rickets ; 

 to gain in body weight ; and to the metabolism of protein, carbohydrate, and fats. 



Protein metabolism, J. J. R. MacLeod {Jour. Lab. and Clin. Med., 1 {1015), 

 No. 2, pp. 112-119). — A summary and digest of data with relation to the utili- 

 zation of free amino acids. 



Recuperation. — Nitrogen metabolism of a man when ingesting succes- 

 sively a nonprotein and normal diet after a 7-day fast, F. D. Zeman, J. Kohn, 

 and P. E. Howe {Avier. Jour. Fhysiol., 36 {1915), No. 4, Free. Amer. Fhysiol. 

 Soc, 27 {1914), PP- 362, 363). — In these experiments the authors determined the 

 urinary nitrogen compounds and changes in body weight occurring after a fast 

 in a 4-day recuperation period on a non-protein diet, and in a 4-day final period 

 on a normal diet. 



An increase in body weight accompanied by a loss of nitrogen occurred during 

 the nonprotein feeding period, while the reverse was true in the final period.
