tion of horses proved valuable in a large percentage of cases in the diagnosis of 

 glanders in horses. The latter method is most difBcult to apply. Although cuti- 

 malleination is reasonably accurate as a test for glanders the hypodermic in- 

 jection of uiallein remains the most reliable method. 



Interpretation of the mallein reaction, R. Racca (Clin. Vet. [Milan], 30 

 (1907), No. 38, PI). 617-621). — If the swelling at the point of inoculation is 

 slight and of short duration and if the temi)erature reaction quickly disappears, 

 the animal is to be considered free from glanders. If, on the other hand, the 

 temperature shovi^s an elevation of 2° C. and the local reaction persists for a 

 day or longer, the horse is glanderous. 



Infectious myelitis in the horse, J. Yaeth (Dcut. Landw. Pressc, 31^ (1907), 

 No. 73, pp. oSo, 586). — In cases of infectious myelitis a preliminary stage of 

 emaciation persists for * to 3 months. Then the hind quarters suddenly become 

 paralyzed, the rate of pulse and respiration is increased, and the temperature is 

 elevated. The conjunctiva turns yellowish. The lesions are found chiefly in 

 the kidneys, spleen, bones, and spinal cord. 



The disease appears to be due to a diplostreptococcus. No satisfactory treat- 

 ment has been devised. 



An enzootic of cataract in horses, C Cuny (Jour. MM. V6t. et Zootecli., 

 58 (1907), Aug., pp. Jt71-Jf78). — A description is given of an outbreak of cataract 

 and keratitis among horses on a farm where no disease of the sort had pre- 

 viously been observed. The trouble was believed to be due to toxins of alimen- 

 tary or bacterial origin. 



The treatment of dourine, V. L. Yakimov (Arch. Vet. Naiilc [St. Petersh.], 

 37 (1907), No. 5, pp. Jfl3-Ji32). — The trypanosomes of dourine were largely de- 

 stroyed in the blood by the use of trypanrot whether adniiuisteted hypodermic- 

 ally or intravenously. In some cases considerable inflammation was produced 

 at the point of inoculation either in the muscles or in the subcutaneous con- 

 nective tissue. 



Dourine in the remount depot at Constantine, Monod (BuJ. Soc. Cent. Med. 

 V^t., 84 (1907), No. 18, pp. .'/.'/8--',.J.5).— A stallion died of a chronic form of 

 dourine without transmitting the disease to any mares. Ocular lesions appear 

 in chronic dourine. A stallion may be infectious for a long time before recog- 

 nizable symptoms of the disease appear. The temperature of susi)ected horses 

 Is not reliable for diagnosis. 



A large dose of virulent blood is necessary to transmit the disease to dogs. 

 Bovine serum sometimes brings about recovery, but iodid of potash, arsenic, 

 cacodylate of iron or soda, and adrenalin are uncertain in their action. 



Susceptibility of the Indian dog to dourine, H. T. Pease (Jour. Trop. Vet. 

 Sci., 2 (1907), No. 3, pp. 310-315). — The pariah dog is not a good test animal in 

 doubtful cases of dourine. The trypanosoma of dourine varied greatly in viru- 

 lence, infection taking place in the dog in only one case. The organism multi- 

 plies at the point of inoculation, causing a local swelling, and attacking the 

 lymphatics before causing a general infection of the blood. The trypanosome 

 may sometimes be found in the infected lymphatic gland. A reliable test ani- 

 mal for the diagnosis of dourine is still to be found. 



Post-mortem glycosuria in rabbits dead of rabies, S. A. Gryuner (Arch. 

 Vet. Nauk [St. Petersb.], 37 (1907), No. 5, pp. 7/32-'///?).— The urine of rabbits 

 dead of rabies was found to contain 0.75 to I per cent of sugar. The sugar ap- 

 peared in the urine whatever the source of the rabies virus used in inoculating 

 the rabbits. Sugar was not observed in the case of any other disease and 

 may, therefore, be considered a diagnostic mark of rabies. 



Chicken pox, H. V. Hawkins (Jour. Dept. Agr. Victoria, 5 (1907), No. 7, 

 pp. 389, 390, fig. 1). — The symptoms of chicken pox are described from a recent
