394 EXPERIMENT STATION RECORD. 



The importance of examining the feces, J. Strasburgee (Berlin. Klinik, 1904, 

 No. 190, pp. 1-20; abs. in British Med. Jour.. 1904, No. 2277, Epit., p. 25).— In a dis- 

 cussion of the importance of examining feces from a clinical standpoint a number 

 of experimental and analytical methods are described. 



The effect of diuretics on the urine, with a diet poor in salts, II. D. H ask ins 

 (Amer. Jour. Physiol, JO (1904), -V<<. 6, pp. 362, 363). — The diuretics tested in experi- 

 ments with a healthy young man did not increase the renal excretion of sodium 

 chlorid even when the water and urea excretion was increased. 



ANIMAL PRODUCTION. 



Analyses of concentrated commercial feeding- stuffs, W. Frear (Pennsylvania 

 stale Dept. Ai/r. Bui. 122, pp. 52). — During the year 1903 the State department of 

 agriculture examined 242 samples of cattle feeds in compliance with the provisions of 

 the State law, including cotton-seed meal and feed, linseed meal, buckwheat mid- 

 dlings; wheat bran, middlings, and feed; rye chops, feed, and gluten meal; barley 

 ehops and feed, and malt sprouts; oat feeds; corn milling products, bran, gluten 

 feeds, hominy meal, and other corn products; mixed feeds with named components, 

 proprietary feeds with the components not named, condimental feeds, and similar 

 goods. 



In addition to chemical analyses the author states that the samples were all exam- 

 ined with the microscope as a means of judging of the specific nature of mixed feeds 

 and the freedom of various samples from adulterants. 



"Briefly reviewed, the year's examination has not shown new types of adultera- 

 tion; but the practice of adding foreign products to feeds sold as mixtures of named 

 grains and of selling without guaranty feeds made in whole or in part from by-prod- 

 ucts still appears very general. Respecting the use of commercial feeds, a final word 

 may not be out of place. For horses and cattle not upon the farm, a great variety of 

 feeds may be used. The farmer, on the other hand, is usually able to grow his 

 fibrous and starchy foods more cheaply than he can purchase them. His need is 

 rather an increased supply of protein with which to supplement and balance up his 

 foods of home production. For this purpose the food purchased must be richer, 

 much richer usually, than corn, which has an average content of 10.3 per cent of 

 protein and 5 per cent of fat." 



Concentrated feeding stuffs, J. P. Street, W. P. Allen, and V. J. Carberry 

 (New Jersey Stas. Bui. 175, pp. 6S). — In accordance with the provisions of the State 

 feeding-stuff law, analyses are reported of cotton-seed meal, linseed meal, gluten meal 

 and feed, hominy meal, corn bran, and similar products; distillery and brewery by- 

 products including, among others, dried distillers' grains, dried brewers' grains, and 

 malt sprouts; molasses feeds; mixed and proprietary feeds; dried beet pulp; ground 

 meat; poultry feeds; barley feed, wheat bran and middlings; ground wheat, rye, and 

 oats; buckwheat middlings, bran, and feed; oat middlings, corn meal, and ground 

 mixed grains. 



According to the authors — 



"Of the 150 different brands of feed received, and which should have been guar- 

 anteed, failed to meet this requirement. 



"Consumers are urged to purchase no unguaranteed material, except mill products 

 like bran, middlings, and corn meal, for which no guarantee is required. 



" Of the 275 samples which are guaranteed, 125 are deficient, 92 of these being low 

 in protein. 



"Of the 122 samples which did not require a guarantee, 91 were of normal composi- 

 tion, 23 were variable, and 8 were adulterated.
