VETERINARY MEDICINE. 



Becent work in tropical veterinary hyg'iene, particularly during 1907 and 

 1908, P. Knuth (Ztschr. Infektionskrnnlc. u. Hyg. Ilaustierc, 6 (1909), No. 2, 

 pp. 180-200; 7 (1910), No. 1-2, pp. i//i-/ 62). —These articles review briefly the 

 more important work of 1907 and 1908. respectively. Bibliographic lists of 72 

 and 140 titles, respectively, are appended. 



Researches on poisonous and other plants, B. C. Aston (Neic Zeal. Dcpt. 

 Ayr. Ann. Rpt., 17 (1909), pp. 178-18-'f). — Toxicological investigations of a 

 number of plants, including ragwort (Scnecio jacobcea), strathmore weed (Pi- 

 melca sp.), waoriki (Ranunculus rivularis), Disearia toumatou, Urtica fcrox, 

 tutu (Goriaria sp.), Dianellw intermedia, Agathis australis, Ocotca sp., and 

 Vt/pcrus rotundus are reported. 



Experiments with barium chlorid, W. E. Frink and H. B. Tillou (N. Y. 

 Blaie Vet. Col. [Pub.] No. 5, pp. 27-39). — "The drug in the doses recommended 

 acts as a purgative, in degrees according to dosage, producing evacuations vary- 

 ing from mild catharsis to drastic purgation. This is produced by increased 

 peristaltic movement and increased intestinal secretion. Furthermore, the drug 

 acts as a cardiac stimulant and tonic, lessening the number of and increasing 

 the force of the beats, and raising blood pressure. The respirations are also 

 reduced in number, but are deeper and more forcible. . . . 



" When given subcutaneously there was some irritation at the point of injection, 

 also more pronounced symptoms of pain. The effect was not seen as quickly, 

 neither did the animal purge as freely. When given by mouth the effect was 

 noted in from 20 minutes to 50 minutes. The animal purged more freely when 

 given in a drench than when administered in a capsule. . . . The subcutaneous 

 and intratracheal methods are unsatisfactory in doses that could be given with 

 safety. The dose of the drug when by the mouth should be 2 dr. for a 1,000-lb. 

 horse and 15 grains should be added to this for each additional hundred pounds 

 weight. From the few exi^eriments on cattle it would appear that the dosage 

 in these animals must be larger than for a horse of the same weight. We would 

 recommend 30 grains intravenously as the minimum dose for a 1,000-lb. cow 

 for mild purgative action." 



The danger of strewing kainit in the bedding of domestic animals, O. 

 Brandes ( tJber die Schddlichkeit des Einstreuens von Kainit in die Stallstrcu
