ground or ungrouiid condition, as the feeder sees tit, though to cattle ground." 

 Bean pods are commonly used as coarse fodder and are liighly praised as a food for 

 sheep. "The universal testimony seemed to be that beans and pods both acted as 

 a laxative and should be fed with great discretion. When fed with care, however, 

 good results were secured." 



Waste beans as stock feed {Pacific Rural Press, 65 [1903), No. 11, p. 262). — The 

 use of stained beans by local dairy and poultry feeders is noted and statements 

 regarding the feeding value of beans are quoted from the article noted above. 



The anatomy of the fruit of certain cultivated, sorghums, A. Ij. Wintox 

 [CuiDiccticitt State ,Sta. Rpi. 1902, pt. .J, pp. S2G-3SS, figs. S). — Microscopical studies are 

 reported of the seeds of a number of sorts of sorghum with a view to accumulating 

 data for use in detecting the materials used to adulterate cattle feeds. A German 

 translation « of this article has previously appeared. 



American wheat screenings, A. L. Winton {Connecticut State Sta. Rpt. 1902, 

 pt. 3, pp. 339-358, figs. 14). — Noted from another source (E. S. E., 14, p. 1101). 



Role of albuminoids in the nutrition of animals, L. Grandeau {Jour. Agr. 

 Prat., n. .ser., 6' {1903), No. 34, pp. 240, 241)- — A brief discussion of the nutritive 

 value of i)rotein and the protein recjuirement of different animals. 



Feeding experiments with materials containing the pyrimidin group, 

 H. Steudel {Ztschr. Phi/slol. Chem., 39 {1903), No. 2, pp. 136-142).— A. brief account 

 of an experiment in which a dog was fed pseudouric acid, isouric acid, etc. 



Subcutaneous alimentation and bile formation, A. G. Barbera {Arch. Ital. 

 Biol, 38 {1902), No. 3, pp. 447-455; abs. in British Med. Jour., 1903, No. 2229, Epit., 

 pp. 43, 44) . — From experiments made with dogs the conclusion is drawn that the 

 subcutaneous injection of nutritive material is of little value and does not compare 

 at all favorably with the results oljtained with rectal feeding. 



The relation between body size and nutrient requirements in the case of 

 dogs at rest and at work, B. Slowtzofp {ArcJi. Phi/siol. Wfiilger'], 95 {1903), 

 No. 3-4, pp. 158-191). — Experimenting with dogs the author determined the respira- 

 tory quotient under various conditions, with the special object of securing data 

 regarding some of the fundamental principles of nutrition in relation to the produc- 

 tion of work. The following conclusions were drawn: For motion of forward pro- 

 gression the work required for a uniform weight and distance is inversely proportional 

 to the size of the animal. Metabolism is directly dependent upon the surface area of 

 the animal in a condition of rest, although it appears that metabolism is not deter- 

 mined by this factor alone. During forward progression the energy expenditure is 

 only approximately proportional to surface area and is affected by other factors 

 which are not well understood. In climbing an incline the energy expenditure 

 varies wdth different animals and no direct connection between it and body size was 

 noted. 



The eflfect of speed, body temperature, and training upon metabolism 

 during rest and work, N. Zuntz {Arch. Physiol. \_Pfli\ger'], 95 {1903), No. 3-4, 

 pp. 192-208).— On the basis of the experiments of B. Slowtzoff, noted above, and addi- 

 tional data from the author's experiments and those of other investigators, the 

 effects on metabolism of speed, body temperature, and skill gained by practice are 

 discussed, and the results obtained with man and the lower animals compared. 

 According to the author it appears that with dogs speed does not markedly affect 

 the amount of material retiuired for unit distance covered, dogs differing in this 

 respect from man and horses. When body temi^erature is increased the amount of 

 material required for the resting body and for the work of respiration is also increased. 

 On the other hand the muscles perform a definite piece of work with the same expend- 

 iture of force as at normal temperature.
