774 EXPEKIMENT STATION RECORD. 



Since the form in which nitrogen is present determines its nutritive value, the 

 author beHeves that it is not possible to learn the nutritive value of proteids by the 

 ordinary analytical methods. 



Influence of formic aldehyde upon the metabolism of children, F. W. Tun- 

 NiCLiFFE and 0. Rosenheim {Jour. Hyg. [Cambridge}, 1 {1901), Xo. 3; ubs. in British 

 Med. Jour., 190^, Xo. 214-3, Epit., p. 16). — From their experiments the authors con- 

 clude that "in healthy children dilute formic aldehyde given with food (1 in 9,000) 

 produces a retention of water in the body, but has no appreciable effect on nitrogen 

 or phosphorus metabolism or fat assimilation, though a tendency in larger doses to 

 diminish phosphorus and fat assimilation, referable to an influence upon pancreatic 

 digestion, is inferred. In a delicate child no retention of water in the body results, 

 and there is a diminution in nitrogen, phosphorus, and fat assimilation, w'ith intes- 

 tinal irritation, referable to interference with pancreatic digestion. In all the cases the 

 excretion of lecithin was diminished, and no intestinal antiseptic action w-as noticed, 

 while the general health remained constant." 



Cleaning' fruit before it is eaten, B. Ehrlich {Arch. Hyg., 41 {1901), Xo. 2, pp. 

 152-176). — A number of instances are cited in which diseases were conveyed by fruit 

 gathered, marketed, or handled under unsanitary conditions. The author points 

 out that micro-organisms adhere readily to the surface of fruits. Experiments were 

 therefore undertaken to determine the number and kinds of such micro-organisms. 

 The smallest number were found on blueberries and plums and the largest number 

 on currants and cherries. It was found to be possible to remove the greater num- 

 ber of micro-organisms by washing. 



ANIMAL PRODUCTION. 



Fodders and feeds {Xew Jersey Stas. Rpt. 1900, pp. 177-lSO). — Analyses are 

 reported of oat and pea forage, hay and straw (manured in different ways), ground 

 oats and peas, alfalfa of different cuttings, alfalfa hay, cowpeas and Kafir corn forage, 

 wheat fodder, crimson clover, ground beans, hominy meal, hominy feed, cotton-seed 

 meal, middlings, wheat bran, pea meal, gluten meal, dried distillers' grains, dried 

 brewers' grains, corn meal, oat feed, and several commercial feeds. The wheat fod- 

 der had the following percentage composition: Water, 77.26; protein, 2.35; fat. 0.68; 

 nitrogen-free extract, 11.97; crude fiber, 5.92; and ash, 1.82. 



Marl-et prices of commercial feeds (pp. 180, 181). — The average market price in New 

 Jersey of a number of feeding stuffs for several years is recorded. 



Inspection of feeding stuffs, W. H. Jordan and C G. Jenter {Xew Tork Stale 

 Sta. Bui. 198, pp. 33-61). — Under the provision of the State feeding-stuffs law analy- 

 ses were made of samples of cotton-seed meal, linseed meal, gluten meal, gluten 

 feeds, germ oil meal, special gluten, malt sprouts, projjrietary feeds (cereal breakfast 

 food by-products), corn bran, barley, poultry foods, offals from milling wheat and 

 rye, and ground grains, chiefiy mixed corn and oats. The bulletin also contains a 

 list of the brands of feeding stuffs licensed in the State for the year 1901, comments 

 on the facts shown by the analysis made, as well as suggestions to manufacturers and 

 consumers. 



Pea- vine hay, W. F. :\Iassey {Bui. Xorth Carolina State Bd. Agr., 22 {1901), Xo. 9, 

 pp. 19, 20). — Directions are given for curing pea-vine hay. 



Hay of Norwegian fodder plants, F. H. Werenskiold {Tidsskr. Xorske Landbr., 

 7 {1900), Xo. 11, pp. 498-509). — Chemical and botanical analyses of 62 samples of 

 hay from grasses and legumes, 28 samples of hay from mountain pastures {sdterho), 

 and 27 samples of marsh and woodland hay {skogho). The ordinary food constituents 

 are given in all cases; also digestible and indigestible albuminoids and amids. —
