in a comatose condition or in a constant struggle to regain their feet, often 

 grunting as if in pain or distress. Deatli would follow in a few hours to several 

 days. Many animals, however, that appeared hale and hearty at the evening 

 meal were found dead the following morning. The most conspicuous symptoms 

 in rabbits and guinea pigs consisted of rapid breathing, lassitude, prostration, 

 and death in a few hours. Sometimes there were continuous movements of limbs 

 after prostration as if to regain their feet, while in others there were no such 

 movements. 



" A comparative study of some of the characteristics of blood from swine 

 fed cotton-seed meal with and without correctives was made. This examination 

 was suggested by the frequency in which dirt, sand, and gravel were found in 

 stomach and intestines at autopsy of swine dead of cotton-seed meal feeding 

 and in the light of the beneficial effects of iron and wood ashes when fed with 

 the cotton-seed meal. ... As regards the variations of hemoglobin and also of 

 the other characteristics of blood, they were as great among individuals of the 

 same lot as between those of different lots. These results bear out former 

 observations that cotton-seed meal has little apparent effect upon the above- 

 mentioned features of the blood. 



" Autopsies were held upon 72 rabbits and 13 swine. . . . Little difference in 

 any of the lesions found in the various lots was noted, except the absence of 

 thrombi (ante mortem clots) in all of the six deaths on iron. The most fre- 

 quent lesions found upon autopsy of animals dead from cotton-seed meal feeding 

 were as previously noted in a former annual report, namely, excess chest and 

 abdominal fluids, congestion of various organs, more or less edema of lungs and 

 frequent thrombi (ante mortem clots) in the heart. The principal difference 

 in the lesions of rabbits and guinea pigs, contrasted with those of swine, con- 

 sisted in the greater excess of abdominal lluld over the chest lluid of the former 

 while the reverse was true of the latter. . . . 



" The yellow jasmine was found to be the cause of death of a number of 

 cattle." 



Sugar beet poisoning, B. F. Kaupp (Awcr. Vet. Rev., 47 {1915), Xo. 4< PP- 

 458-462). — The author reports upon observations of sugar beet poisoning in 

 live stock made while pathologist at the Colorado Experiment Station. It is 

 pointed out that while tops, beet pulp, mangel wurzels. etc., furnish extra feed if 

 fed judiciously, only a part of the animal's ration should consist of them. Sugar 

 beet pulp fed gradually in excess for long periods causes fatty degeneration, 

 especially of the liver and kidneys, and excessive fee<ling of beets and beet tops 

 may cause gastroenteritis with parenchymatous degeneration of the liver and 

 kidneys. 



A contribution to the practical utility of Abderhalden's dialysis procedure 

 for the early diagnosis of pregnancy, II. Kaehiger, E. Wiegeut, E. Seibold, 

 and A. Roecke {ncrlin. Ticriirztl. Wchnschr., SI {1915), No. 8, pp. 85-91).— 

 Fifty-two sera (47 from bovines and 5 from horses) were examlnetl. 2.5 of which 

 (24 from bovines and 1 from horse) were obtained from slaughterhouses. The 

 remaining 27 sera were sent in from breeding establishments by veterinarians 

 and included 23 bovines and 4 horses, 20 of these animals being pronounced 

 pregnant by clinical examination, and no history of pregnancy in the remaining 

 7 being obtainable. 



The examination of blood samples from the slaughterhouse showed positive 

 in 22 cases. In the remaining 27 blood samples 3 gave an erroneous diagnosis 

 with the method, but 2 of these cases, three and a half months later, gave a cor- 

 rect result. The author is of the opinion that results may be obtained by the 

 Abderhalden method which will be of value in practice.
