558 EXPERIMENT STATION RECORD. > [Vol.41 



It is also considered that larger use could be made of it as a feeding stuff. 

 A 13-week trial by F. W. WoU at University Farm, Davis, is noted in which 

 carob bean pods were compared with ground barley as supplements to ground 

 milo maize (1:1) for skim milk calves. The calves relished the pods greatly, 

 and 0.4 lb. practically offset 0.35 lb. ground barley. 



Pumpkin as flour substitute, E. Alpers {Ztschr. Untersiich. Nahr. u. 

 GennsswtL, 36 (1918), No. 11-12, pp. 281, 2S2).— Satisfactory bread was made 

 with the use of from 10 to 20 per cent of the thick pulp of cooked pumpkin 

 in place of a corresponding amount of flour. The pumpkin gave a slight yel- 

 low color and characteristic flavor to the bread, but was thought to be su- 

 perior to beets as a flour substitute. 



Reports of storage holdings of certain food products during 1918, J. O. 

 Bell (17. S. Dept. Agr. Bui. 192 (1919), pp. 80, figs. -}0).— This is the third bul- 

 letin in the series previously noted (E. S. R., 41, p. 66). It reports data as to 

 the storage holdings during 1918 of frozen and cured meats, lard, frozen fl.sh, 

 cured herring, and mild cured salmon. 



Swiss food 'book iScliiceizerisclies Lehensmittelhucli. Bern: Schweiz. Ver. 

 Anahjt. Chem., 1917, 3. rev. ed., pp. XXVII +420). —This is the third revised 

 edition, edited by the Swiss Society of Analytical Chemistry, of methods of 

 investigation and standards of valuation of foods, household utensils, and 

 commodities. Among the food products treated are milk and dairy products, 

 edible fats and oils, meats, cereal products, eggs, honey, sugar and confection- 

 ery, fruit products, spices, nonalcoholic and alcoholic beverages, and vinegar. 



Dependence of the protein requirement on the mineral metabolism, C. Rose 

 and R. Berg {Mimchen. Med. Wchnschr., 65 (1918), No. 37, pp. 1011-1016; abs. 

 in Chem. Abs., 13 (1919), No. 11, p. 1222). — This is a discussion of the mainte- 

 nance of neutrality in the body, based largely upon metabolism experiments. 



The protein requirement was found to be at a minimum if the experimental 

 ration contained a sufficient excess of bases during the fore-period and time 

 of the experiment itself. Insufficient bases during the fore-period and a. suf- 

 ficient excess during the main period were found to increase the protein re- 

 quirement during the latter period from 5 to 20 per cent, while a sufficient 

 excess during the fore-period and deficiency during the main period increased 

 the protein requirement from 10 to 50 per cent. An insufficient excess of 

 bases during both periods increased the protein requirement from 50 to 300 

 per cent. 



On a diet rich in acid-forming elements the energy utilization was found to 

 be less, and consequently the energy requirement greater, than on a diet 

 rich in base-forming elements. For this reason, it is considered necessary in 

 the determination of the protein requirement to consider whether the ration 

 is rich in acid-forming or in base-forming materials. 



Accessory factors of growth and equilibrium: Vitamins; auxlmones, G. 

 ScHAEFFEE (Bul. hist. Pusteur, 17 (1919), No. 1, pp. 1-21, figs. 6; 2, pp. 41-59, 

 figs. Jf). — This is a review and discussion of the literature on vitamins, sym- 

 biotes, and auximones. A bibliography of 44 titles covering the literature on 

 the subject during 1917-18 is appended. 



A lecture on the practical importance of vitamins, F. G. Hopkins (Brit. 

 Med. Jour., No. 3043 (1919), pp. 507-510). — A general discussion of the subject. 

 • Vitamins and fungi, G. Linossier (Gompt. Rend. Soc. Biol. [Paris], 82 

 (1919), No. 11, pp. 381-384).— The author has found that OUiuni lactis, al- 

 though capable of developing on media exclusively composed of mineral suc- 

 stances and a simple carbohydrate-forming food such as alcohol, acetic acid, 

 glycerin or glucose, is sensitive to the action of vitamins. This sensitiveness is
