178 EXPEKIMENT STATION RECORD. 



dogs are reported, in which the lialance of income and outgo of nitrogen was deter- 

 mined. In one case the carbon dioxid and water in the respired air were also deter- 

 mined. The principal conclusions follows: Omitting water from the diet increased 

 the cleavage of protein in the body and had no effect on the cleavage of fat. When 

 it does not produce pathological symptoms it is without effect on the blood pressure. 

 The effect on protein of the withdrawal of water from the tissues is noticeable until 

 the body regains its normal water content. Omitting water from the diet affects in a 

 sHght degree the amount of water excreted through the lungs and skin. 



The physiological action of electric currents of high tension and great fre- 

 quency, N. >^i'\sf<Ki {PIti/siolofjiste Russe, 1 (1899), Xo. 15-20, pp. -235-341, pJ. 1).— 

 A form of apparatus for measuring and analyzing the respiratory products, devised in 

 connection with the investigation, is described and experiments with guinea i>igs 

 reported. 



The heat of combustion of meat of different animals, Studensky {Russ. Arch, 

 Patol. Klin, i BakL, 7 [1899), p. 305; abs. in Physnologiste Russe, 1 {1899), No. 15-20, 

 pp. 303, 304). — Experiments showed that the heat of combustion of the flesh of 

 horses, sheep, and foxes varied very little and was on an average 5,738 calories per 

 gram ash-free flesh. 



The determination of animal heat by direct calorimetric methods and by- 

 means of the metabolism of material, P. P. Avrorov {Russk. Arch. Patol. Klin, i 

 Bakt., 7 [1S99), ]>. 207; aU. in Pln/.^iologiste Russe, 1 (1899), No. 15-20, pp. 301,302).— 

 A water calorimeter is described which measures directly the heat produced by an 

 animal. Devices are also described for the measurement and analysis of the respira- 

 tory products. 



Improvement of pasture as determined by the eflPects on the stock, \V. Som- 

 ERViLLE (Trans. HigMand and Agr. Soc. Scotland, 5. ser., 12 (1900), pp. 75-97). — A dis- 

 cussion of experiments abstracted from another source (E. S. R., 12, p. 75). 



Canadian experiments in animal growth and dairy products, W. Brown 

 ( Trans. Highland and Agr. Soc. Scotland, 5. ser., 12 (1900), pp. 137-161, fig. 1).—A gen- 

 eral discussion based on the experiments of the Canadian experiment stations in 

 animal feeding and dairying. 



Contributions to our knowledge of the physical properties of Swedish wool, 

 G. Sellergrex (K. Landt. Akad. Handl. Tidskr., 38 (1^99), Nos. 5-6, pp. 344-390, figs. 

 30). — The author gives a historical account of Swedish sheep raising, a description 

 of the various breeds of sheep with reference to the quality of the wool, methods and 

 aiJi^aratus used in wool examinations, and the results of the investigation. Sixty 

 samples of wool were examined in all, according to crimp, fineness, length, elasticity, 

 .strength, color, and microscopic appearance. Among the breeds represented were 

 i\Ierinos, Cheviots, Southdowns, Dishleys, Oxfordshire Downs, and native sheep. 



The value of succulent foods for swine, C. S. Plumb ( Reprint from Breeders' 

 Gaz., 1899, Dec. 20 and 27; 1900, Jan. 3, pp. 16). — The author summarizes briefly the 

 results of a large number of experiments on the value of roots, etc., for swine. 



The preparation of feed and the feeding of swine, J. Kappeli (Jahresber, 

 Landv. Schule Riitti, 1898-99, pp. 61-67).— From a feeding and slaughter experiment 

 with 2 lots of 3 pigs each, the conclusion was drawn that animals fed uncooked whole 

 grain (barley and corn) in the first month of the test consumed less feed than those 

 receiving meal ground from the same grains moistened with hot water. Pigs fed 

 whole and raw grain increased much more rapidly until they were 9 months old than 

 those fed soaked meal, while during the last six weeks of the test the increase was 

 somewhat less. 



Pig raising in Tunis, J. A. Tournieroux (Bui. Dir. Agr. etCom., 5 (1900), No. 

 14, pp. 68-74, fig. 1)- — Pigs and pig raising under local conditions in Tunis are dis- 

 cussed. 



Zebra hybrids (Trans. Highland and Agr. Soc. Scotland, 5. ser., 12 (1900), pp. 385- 

 388). — A brief summary of J. C. Ewart's experiments.
