880 EXPERIMENT STATION RECORD. 



has no poisonous effect on chickens, as shown by experiments in which they were 

 fed exckisively on castor pomace for 8 days without injury. 



The cost of shredding fodder ( Wallaces' Farmer, 26 {1901), No. 43, p. lUl)-— 

 Estimates of $2.28 and $3.08 per acre and $2.50 per ton are given by practical farm- 

 ers. The estimate of $2.50 per ton is accompanied by the statement that an acre of 

 corn yields about 2 tons of shredded fodder. 



Chemistry of the animal body in relation to cell life, especially the blood, 

 L. H. W.\RNER {Dletet. and Hyg. Gaz., 18 {1902), No. 1, pjx ^7-i£i).— A discussion 

 summarizing some of the general principles of the subject. 



On the resorption of substances insoluble in water, H. Friedenthal {Arch. 

 Tkysiol. [Pfluger], 87 {1901), No. 8-9, pp. ^67-^7-').— Fatal results showing the char- 

 acteristic symptoms of quicksilver poisoning followed the administration of metalUc 

 quicksilver to rats and cats. In the author's opinion the quicksilver must have been 

 absorbed. This investigation was discussed in relation to the passage of fat through 

 the intestinal wall. 



The passage of protein through the intestinal wall, O. Cohnheim {Ztschr. 

 Physiol. Chem., 33 {1901), No. 5-6, pp. ^2-^55).— Experiments by the author led to 

 the conclusion that the disappearance of peptone when in contact with the intestinal 

 wall as observed by Hofmeister, Neumeister, and Salvioli, does not depend upon 

 assimilation or rebuilding of albumen, but rather upon its cleavage to simpler i^rod- 

 ucts. This cleavage, the author believes, is brought about by a ferment secreted hy 

 the mucus membrane of the intestine for which the name erepsin is proposed. This 

 acts upon peptone and some albumoses, but not upon albumen itself. 



The formation of glycogen from protein, B. Schondorff {Arch. Physiol. 

 [Pfli'iger'], 88 {1901), No. 6-8, pp. 339-346).— K controversial article. 



The influence of gall on metabolism, A. Landauer {Math. u. Nalurw. Ber. 

 Ungarn IBerlin v. Budapest], 15 {1897), pp. 75-114). — Experiments with dogs are 

 reported, also a biVjliography of the subject given. 



The feeding of animals, W. H. Jordan {Nciv York and London: The Macmillan 

 Company, 1901, pp. XVII -\- 450, figs. 10). — This volume includes a summary of the 

 principles of nutrition with special reference to the feeding of farm animals. It 

 contains chapters discussing the composition and requirements of the animal body, 

 nutrients, feeding stuffs, digestion and assimilation, rations for growth, meat and 

 milk production, production of force, the management of farm animals, and related 

 topics. Tables showing the composition and digestibility of the more important 

 American feeding stuffs are included, as well as the commonly accepted feeding 

 standards, and a comprehensive index is a noteworthy feature. The author has 

 embodied in this work the conclusions drawn from investigations made at European 

 and American experiment stations, as well as the results of his own extended experi- 

 ence as an investigator and teacher, and the work constitutes a valuable summary 

 for students and for general readers. The chapter on the feeding of poultry was 

 contributed by W. P. Wheeler. 



Stock feeding in the South, D. R. Pillsbry {Tradesman, 46 {1902), No. 9 [23. 

 annual'], pp. 131-133, figs 3) . — A discussion with reference to local conditions. 



Study of breeds in America; cattle, sheep, and swine, T. Shaw {New York: 

 Orange Judd Co., 1901, jjp. 371, pi. 1, figs. 53). — The available information regarding 

 the different breeds of cattle, sheep, and swine is arranged in systematic order and 

 supplemented by much information regarding the general subject of breeds and 

 breeding. The volume is especially designed to suit the needs of students of 

 agriculture. 



Methods of steer feeding, G. C. Watson and A. K. Risser {Pennsylvania Sla. Bui. 

 57, pp. 11; Pennsylvania Depl. Agr. Bui. 84, pp. 16) . — Continuing previous work ( E. S. 

 R., 12, p. 875) on different methods of confining steers, as well as different methods of 

 supplying drinking water, 2 tests with steers are reported, which were carried on by
