258 EXPERIMENT STATION EECORD. 



In addition, they conclude that "the activity of pancreatic juice to which 

 hydrochloric acid has been added suggests that this secretion is capable of hydro- 

 lyzing the starch of a dietary to dextrose. Pancreatic juice alone or in the 

 presence of neutral salts, acids, or alkalis, has no action on lactose or cane 

 sugar." 



Earlier work has been noted (E. S. R., 32, p. 859). 



Lipo-cholesterin variations during' inanition and feeding experiments, 

 E. F. Terroine {Jour. Physiol, et Path. Gen., 16 {1914), ^'o. 3, pp. 386^97)-.— 

 Examinations of the blood of laboratory animals during periods of starvation 

 and food ingestion indicated that its composition varied considerably as regards 

 water, fatty acids, and cholesterin. The cholesterin content diminished regu- 

 larly during the early periods of inanition. When a fat-rich diet was eaten, an 

 increased amount of both fatty acid and cholesterin appeared in the blood, 

 regardless of the cholesterin content of the food. The ratio of cholesterin to 

 fatty acid remained remarkably constant. 



The value of extractives in nutrition, H. Aeon {iIo)wtsschr. Kinderheilk., 

 Orig., 13 {1915), No. 8, pp. 358-380). — Feeding experiments with laboratory 

 animals (rats) are described, and the course of growth illustrated by charts. 



With the addition of an extract of wheat bran to a basal ration of starch, fat, 

 casein, and salts, the animals thrived and increased in weiglit. Extract of malt 

 gave similar results, but its action was slower. When the basal ration alone 

 >vas consumed, the animals lost weight and finally died. 



Nutrient enemas, V. Scheel and E. Begtrup {Ugeskr. Lager, 77 {1915), yo. 

 l.'i, pp. 5.'i3-551 ; ahs. in Jour. Amer. iled. Assoc, 6^ {1915), Xo. 21, p. 1804). — 

 The clinical experience of the authors showed the good ab.sorption and utilization 

 of suitable nutrient enemas. Milk and eggs were not properly absorbed, but 

 amino acids prepared by the digestion of meat or milk by trypsin-erepsin were 

 used to supply from 400 to 600 calories daily with good results. 



Albumin milk in infant feeding, V. Poxtlsex {Ugeskr. Lager, 77 (1915), No. 

 22, pp. 8'75S92). — Clinical observations upon 85 infants under one year of age 

 and 29 children from one to five years old are reported. No advantages were 

 noted from feeding albumin milk in cases of acute gastro-enteritls, but in chronic 

 dyspepsia good results were obtained in nearly every case. 



Homogenized olive oil and fat-free milk mixtures in case of difficult feed- 

 ing, M. Ladd {Arch. Pcd., 32 {1915), Xo. 6, pp. 409-425).— The author reports a 

 number of clinical observations and describes a method of administering homo- 

 genized olive oil as a substitute for cream in case of fat intolerance in infants. 



Some studies on sugar in infant feeding, L. Porter and C. H. Dunn {Amer. 

 Jour. Diseases Children, 10 {1915), Xo. 2, pp. 77-86). — Clinical observations 

 upon 18 infants supplemented by analytical data are reported, from which the 

 authors conclude that the dangers of sugar injuries and sugar intoxication have 

 been exaggerated, and that in cases of mild fat intolerance it may be desirable 

 oftentimes to meet the energy requirements by using large quantities of soluble 

 carbohydrate. 



Some observations further incriminating sugar cane products as the main 

 cause of pellagra in the south, R. Blosser {South. Med. Jour., 8 {1915), No. 1, 

 pp. 33-36). — Observations are reported of 133 pellagrins, all but 3 of whom had 

 eaten large amounts of cane sugar and sirups. The author states that the ex- 

 clusion of sugar and other cane products from the diet resulted in a cure for 

 121 cases, while 8 improved markedly and only 4 died. 



Experimental pellagra in the human subject brought about by a restricted 

 diet, J. GoLonERGER and G. A. Wheeler {Pub. Health Hpis. [('. S.]. 30 {1915). 

 No. 46, pp. 3336-3339). — ^A brief outline is given of experimeuts planned to study
