author fo)ind that " «igiis of emotion, such as fear, distresg, or rage, are acc^ompanied 

 by a total cessation of the movements of l)oth large and small intestines. The move- 

 ments continue in the cat both during sleep and at night." Other conclusions 

 regarding the movements of the food in the intestines, etc. , are given. 



Digestion in the small intestine, F. Kutscher and J. Seemann {Ztschr. Physiol. 

 Chem., 34 [1902), No. 5-6, pp. 5^8-543). — From experiments reported in detail, the 

 conclusion was drawn that under normal conditions trypsin induces in the small 

 intestine a cleavage of protein to such an extent that crystallizable products are 

 formed. Of these the authors have identified only leucin, tyrosin, lysin, and argi- 

 nin. Such cleavage products may be so changed in the intestinal wall that they 

 are unrecognizable. Noticeable amounts of albumoses and peptones were not found 

 in the intestinal contents. 



The metabolism of phosphorus, calcium, and magnesium by herbivora, 

 F. Taxgl [Arcli. PJnjsiul. [Ptli'iger], 89 {1903), No. 5-6, pp. 227-239).— X numl)er of 

 experiments with horses on the metabolism of phosphorus, calcium, and magnesium 

 are reported. According to the'author, these show that a certain parallelism exists 

 between the metabolism of nitrogen and phosphorus. The amount of phosphorus, 

 calcium, and magnesium required per kilogram body weight is discussed, as well as 

 related topics. 



Concerning the metabolism of horses, T. Pfeiffer {Landir. Ven. Slat., 56 

 (1902), No. 4, Pl>- 28S-2SS) . — A controversial article. 



Remarks on Pfeitfer's criticisms, N. Zuntz and O. Hagemann (Landw. Vers. 

 Stat., 56 (1902), No. 4, PP- 289-292).— A reply to the above. 



Steer feeding experiments, J. H. Grisdale {Canada Expt. Farms Rpts. 1901, 

 pp. 277-290). — Continuing earlier work (E. S. R., 13, p. 270), several feeding tests 

 with steers are reported. The comparative gains made by calves, yearlings, 2-year- 

 olds and 3-year-olds was studied with 4 lots, lot 1 containing 5 animals, and the other 

 lots 9 each. The calves in lot 1 were fed for 196 days, the other animals for 203 

 days. The calves gained on an average 2.09 lbs. jier day, the cost per pound of gain 

 being 3.24 cts. The yearlings, 2-year-olds, and 3-year-olds gained respecti\ely 1.55, 

 1.58, and 1.76 lbs., the corresponding cost of a pound of gain being 5.77, 5.71, and 

 6.37 cts. 



The comparative gains made by dehorned steers and those not dehorned were 

 tested with 2 lots of 9 each. The former were loose — the latter tied in stalls. The 

 average daily gain under similar conditions of feeding was 1.78 and 1.7 lbs., I'espec- 

 tively; the cost of a pound of gain 6.55 and 6.60 cts. The gain made by large and 

 small lots of dehorned cattle, all loose, was tested with 3 lots containing respectively 

 9, 6, and 3 steers. The average daily gains were 1.78, 1.79, and 1.7 lbs., the cost of 

 a pound of gain being 6.55, 6.25, and 6.76 cts. 



The test previously reported (E. S. R., 13, p. 270) on the comparative merits of a 

 limited and a full fattening ration was continued under practically the same con- 

 ditions, and a second test with 2 lots of 5 calves each undertaken. The average 

 daily gain in the new test (covering 28 weeks) on a full fattening ration was 1.92 lbs., 

 and the cost of a pound of gain 2.6 cts. On a limited growing ration the corre- 

 sponding values were 1.68 lbs., and 2.49 cts. The average daily gain in the test 

 covering a year on the limited ration was 1.14 lbs., the cost of a pound of gain 3.42 

 cts., the daily gain on a full ration 1.9 lbs., the cost of a pound of gain 8.53 cts. 



Steer feeding; dehorning, R. Robertson, S. A. Bedford, and A. Mackay 

 {Canada Expt. Farms Rpts. 1901, pp. 360-365, 422-427, 507-510, pi. 7).— At thfl 

 Experimental Farm of the Maritime Provinces the comparative merits of feeding 

 loose and tied in stalls was tested with dehorned and not dehorned .steers. One lot 

 of steers fed loose in a box stall was led to water, the others w^ere not. Three of the 

 lots contained 8 animals and one of the lots 4. The dehorned steers fed loose gained 

 231 lbs. and those tied 286 lbs. each, on an average. The steers not dehorned fed
