finally extracting the colchicin from the aqueous-solution residue with chloro- 

 form. The chloroform residue may be hydrolyzed with hydrochloric acid and 

 tested with ferric chlorid. which gives a blue coloration, or it may be tested 

 as regards toxicity by injection into white mice. 



Lysol poisoning in various domestic aniraals, B. Potting {Berlin. Tier- 

 arztl. WchnscJir., 27 (1911), No. 16, p. 286). — In most of the instances where 

 symptoms of poisoning could be noted this antiseptic had been applied exter- 

 nally. The pig was the most sensitive. No cases were noted in bovines. 



Upon the proteolytic bacteria and the intestinal flora of man and animals, 

 A. DiSTASO (Cciithl. Bald, [ctc.^, 1. AU., Orig., 59 (1911), Xo. 2, pp. 97-103, 

 figs. 9). — A description of the following organisms and a discussion in regard 

 to their relation to man, animals, nutrition, cheese, milk, and putrefaction : 

 Bacillus putriflcus coagulans n. sp., B. putriflcus filamentosus n. sp., B. sporo- 

 genes sooglcicns n. sp., B. sporogenes saccharolyticus n. sp., B. sporogenes regu- 

 laris n. sp., B. multiformis n. sp., B. tenuis spatuliformis n. sp.. Staphylococcus 

 liqiiefacicns aiira)itiaciis n. sp., Coccoiacillus liquefacicns n. sp., B. rigidus n. sp. 



Research in regard to infectious diseases at the present time, P. Fkoscii 

 (Berlin. TierarzU. Wchnschr., 27 (1911), No. 21, pp. 373-^77).— This is a de- 

 tailed lecture upon the present status of research in infectious diseases, deliv- 

 ered at the Royal Veterinary High School of Berlin. 



Infective methaemoglobinaemia in rats caused by Gaertner's bacillus, 

 A. E. Boycott (Jour. Hyg. [Cambridge], 11 (1911), No. 4, pp. U3-Ii72, figs. 

 3). — "A spontaneous epidemic of Gaertner infection among rats was found 

 associated with methsemoglobinfemia and, in some cases, antemia. Strains of 

 Gaertner's bacillus isolated from these rats reproduced niethtemoglobinfemia 

 in fresh rats but not in rabbits, guinea pigs, or mice. Other strains of Gaert- 

 ner's bacillus from rats, guinea pigs, and human sources also caused methremo- 

 globinaemia either before or after passage through rats. Other organisms 

 pathogenic for rats did not produce methtemoglobiuoemia." 



Is paroxysmal hemoglobinemia an infectious disease? C. Cuny (Jour. 

 M6d. V^t. et Zootech., 61 (1910), Mar., pp. 129-139; abs. in Berlin. Tierdrstl. 

 Wchnschr., 27 (1911), No. 30, p. 540).— The author does not believe that this 

 is a bacterial disease. Cold seems to be one of the chief etiological factors. In 

 the cases observed by him fever was never present before the hemoglobinemia 

 proper set in. 



Bush disease, B. C. Aston (Jour. New Zeal. Dept. Agr., 3 (1911), No. 5, 

 pp. 394-399, figs. 3). — The evidence obtained during a period of over 14 years 

 is said to show that the condition of live stock, known locally as "bush disease" 

 or " bush sickness," which occurs in the Rotorua, Matamata, and Tauranga 

 Counties, is a condition resulting either from a food supply wanting or deficient 

 in some essential nutrient, which therefore results practically in starvation, 

 or a food supply containing naturally or adventitiously (1) some toxic com- 

 pound, or (2) some normal constituent present in abnormal quantity, resulting 

 in chronic poisoning. 



The spirochetes of gangrene of the lungs and ulcerating carcinoma, G. 

 Arnheim (C'entbl. Bakt. [etc.], 1. Abt., Orig., 59 (1911), No. 1, pp. 20-3^ 

 pis. 2). — The spirochetes which occur in the carcinomas in man and animals 

 represent a species of sui generis. The colonies can not be distinguished from 

 one another. No proof as regards the etiological relations of spirochetes to 

 carcinoma has thus far been established, but according to the author it seems 

 peculiar that they are often present in carcinoma. The spirochetes which 

 are usually present in gangrene of the lung were found to be identical with 

 those usually found in the buccal cavity (Spirochwta dentium).
