FOODS — HUMAN NUTRITION. 861 



[Report of food and drag laboratory], H. E. Barnard (Tnd. Bd. Health, 

 Ann. Rpt. Chem. Div. Lab. Hyy., 9 (1915), pp. 1-153, figs. 39).— The work of the 

 laboratory during the year ended September 30, 1914, is reviewed. This in- 

 cluded the analysis of 1,703 samples of miscellaneous foods, of which 1,279 were 

 found to be legal, and of 294 samples of drugs, of which 261 conformed to 

 existing standards. Sanitary inspections were made of 12,106 places, including 

 grocery stores, meat markets, drug stores, bakeries, hotels, and restaurants, 

 of which 50 per cent were found to be in good condition. 



Special reports are given of a sanitary survey of canneries and bottling 

 works operating in the State. Reprints are included of A Study of Fruit Jar 

 Caps, by Cxail M. Stapp (E. S. R., 32, p. 856), and The Effect of Bread Wrapping 

 on the Chemical Composition of the Loaf, by H. E. Barnard and H. E. Bishop 

 (E. S. R., 32, p. 354). Reprints of various instructions and notices issued 

 by the food commissioner conclude the report. 



Electric cooking in a cafeteria, B. E. Hannon {Jour. Electricity, 36 (1916), 

 No. 15, pp. 280, 281, figs. 2). — ^The electric cooking equipment of a cafeteria is 

 described in detail, cost data being included. 



School lunches, Caroline L. Hunt and Mabel Ward (U. S. Dept. Agr,, 

 Farmers' Bid. 712 (1916), pp. 27). — Although this publication was prepared pri- 

 marily to furnish information regarding the foods best suited for the children's 

 noon meal and for the school lunch basket, it emphasizes the fact that all 

 three meals in a day's ration must be considered together and considerable 

 space is devoted to the general food requirements of children. General infor- 

 mation and suggested bills of fare are given for the home lunch, for the basket 

 lunch, and for meals prepared at school. A few recipes for school-lunch 

 dishes are included. 



The child and its care, Neale S. Knowles, Louise H. Campbell, and Mabei, 

 C. Bentley (Iowa State Col. Agr. Ext. Dept., Home Econ. Bui. 2 (1915-16), pp. 

 32, figs. 14). — Considerable information is contained in this bulletin regarding 

 the diet of infants and of children three years of age or more, suggestive lists 

 of foods and menus being included. Hints are also given regarding the per- 

 sonal hygiene and clothing of children. 



The physiology of the newborn infant. Character and amount of the 

 catabolism, F. G. Benedict and F. B. Talbot (Carnegie Inst. Washington Pub. 

 233 (1915), pp. 126, figs. 10). — In this publication the authors refer to earlier 

 researches with newborn infants by other investigators and to the former paper 

 by themselves (E. S. R., 32, p. 461). A translation is given of an article 

 reporting respiration experiments with newborn infants, by K. A. Hasselbalch, 

 who draws the conclusion that a well-nourished infant born at full term has 

 a store of carbohydrates (glycogen) in its organs which is spent in the course 

 of a few hours and that " the metabolism of a poorly nourished and premature 

 infant depends chiefly on the oxidation of carbohydrates during the first 

 hours of life." The conclusions of Hasselbalch are discussed by the authors 

 in the light of other experiments. 



The experiments here reported consist of observations of the metabolism of 

 105 newborn infants and include several hundred experimental periods. The 

 technique employed is described in detail and the statistics of the observations 

 are presented in tabular form. 



An analysis of the data for the minimum metabolism periods shows that on 

 the first day of life there are important temperature regulation disturbances 

 which result either in a decreased metabolism, or an increased metabolism 

 when there is an effort on the part of the infant to compensate for the loss of 

 heat. After the second day there is a fair uniformity in the heat production
