The rural school luncheon (Regina, Canada: Govt., 1916, pp. 40, pi. 1, figs. 

 9). — This pamphlet, which was issued by the Department of Education, Sas- 

 katchewan, as Household Science Circular No. 1, contains information regard- 

 ing the equipment and supplies to be furnished by the school board and the 

 duties of the teacher and the mothers, and gives recipes and directions for the 

 preparation of the luncheon. 



Studies in carbohydrate metabolism, XIV-XX, Louise McDaiteij. and 

 F. P. Underhill {Jour. Biol. Chem., 29 (1917), No. 2, pp. 227-232; 233-2^3; 

 245-250; 251-254, fig. 1; 255-263; 265-272, fig. 1; 273-280 ) .—Seven articles are 

 here presented. 



XIV. The influence of alkali administration upon blood sugar content in rela- 

 tion to the acid-base-producing properties of the diet. — Tlie data here reported 

 indicate that the injection of sodium carbonate is as ineffective in altering the 

 blood sugar content of normal laboratory animals (rabbits) when maintained 

 either upon acid-forming or base-forming diets as is the case with animals 

 receiving a mixed diet 



XV. The influence of acid-forming and base-forming diets upon blood sugar 

 content. — Experiments with normal laboratory animals (rabbits) showed that 

 the blood sugar content was not changed by variations in the acid-base content 

 of the diet which were sufficient to cause a marked change in the hydrogen ion 

 concentration of the urine. 



XVI. The relation of cpinepfirine glycosuria to dosage and to (he character of 

 the diet. — The following conclusions are drawn in part from the data reported : 



With a sufficient quantity of food, laboratory animals (rabbits) maintained 

 upon a mixed diet excreted larger amounts of sugar after epinephrine adminis- 

 tration than when maintained upon either an acid-producing diet or one yield- 

 ing a basic ash. During a base-forming diet a somewhat larger output of ^ugar 

 occurs after injection of epinephrine than is the case under similar conditions 

 with an acid-producing diet. It is possible that there is a greater glycogen 

 storage upon a base-producing diet than uix)n a diet yielding acid ash. 



XVII. Further experiments upon the influence of the intravenous injection 

 of sodium carbonate upon epinephrine hyperglycemia and glycosuria. 



XVIII. The relation of diet to the glycogen content of the liver. — Studies of 

 the influence of the diet upon the glycogen content of the liver were carried out 

 with normal laboratory animals (rabbits). 



It was found that a base-forming diet Is somewhat more efficient in the 

 formation of glycogen than an acid-producing diet. These results are in agree- 

 ment with those of other investigators, who have found that an excess of alkali 

 contributes to the accumulation of glycogen. However, it was also demon- 

 strated that a large storage of glycogen may take place upon an acid-forming 

 diet when sufficient food is ingested. 



XIX. The influence of the intravenous injection of sodium carbonate upon 

 the hyperglycemia and glycosuria following the subaitancous administraion of 

 glucose. 



XX. New experiments upon the mechanism of salt glycosuria. 



A chemical study of prolonged inanition, R. E. Swain (Jour. Biol. Chcm.. 

 29 {1917), No. 2. p. XA'.VT").— This is a brief report of observations on a 30- 

 year-old man, who subjected himself to a starvation period of 60 days. 



Preliminary observations on the regulation of the calcium excretion in 

 the dog. M. H. Givens {Jour. Biol. Chem., 29 {1917), No. 2, p. XXIV).— In a 

 laboratory animal (dog) maintained in nitrogenous equilibrium for 60 days, 

 negative calcium balance was brought about by a diet of meat, lard, and cracker 

 meal. The substitution for cracker meal, on the basis of nitrogen and calorie 

 equivalent, of dried skim milk and .sucrose resulted In an approach toward a
