Observations on recovery from glanders, Morii.LKuo.N [liec. Med. 17/., <s'. scr., 

 10 {1903), No. 24, PP- 530-585). — Clinical notes are presented on 4 cases of glanders 

 in horses which ultimately recovered entirely. The horses were given mallein injec- 

 tions at intervals <luring periods of .3 to 4 years. Finally each horse was killed and 

 subjected to a careful post-mortem examination and mieroscropic study. Material 

 was also taken for use in the inoculation of male guinea pigs. Negative results were 

 obtained from all these tests for the presence of the glanders l)acillus. 



Immunity toward contagious coryza, J. ScHxtJRER {Zt-srJir. Tliierrncd., 7 (1.003), 

 No. 3-4, pp. 286-307). — The literature of this subject is critically discussed by the 

 author. A numl)er of cultures of the streptococci of contagious coryza were examined 

 by the author, in all 13 cases in horses. This organism was found in an abscess of 

 infected laryngeal lymph glands. Notes are given on the biology of this organism. 



All cultures obtained by the author were found to be virulent for white mice. 

 Tliese animals died within 2 to 4 days after inoculation. Strejitococci, howevei", were 

 only slightly virulent for rabbits and guinea pigs. Experiments were made on white 

 mice, rabbits, and 1 ass, for the purpose of testing the i")Ossibility of imnnmizing ani- 

 mals against this disease. During these experiments it was found that no substance 

 was present in the serum of horses affected Mitli spontaneous cases of contagious 

 coryza or artificially imnuinized against this disease, which had any active influence 

 in checking the progress of the disease in experimental animals. 



Mai de caderas afifecting- horses, G. d'Utra {Bol. Arjr. Sao Faido, 4- w-, 1903, 

 No. 11, pp. 501-520). — The literature relating to this subject is critically discussed. 

 Notes are given on the ordinary clinical forms of mal de caderas, including the 

 chronic and paralytic forms. The treatment of the disease is also briefly discussed 

 and reference is made to the agency of insects in carrying the l)lood parasite. 



Mal de caderas in South. American horses, J. Ligniekks [Rec. Mi'd. Yi'L. 8. 

 ser., 10 {1903), Noa. .2, pp. 51-69; 4, jip. 109-134; 6, pp. 164-190, ph. 2) . — This disease 

 is due to infection l)y Tri/jKino^oma dma.^xutni. Notes are given on the morphology 

 of the organism and its various developmental forms. Special attention is devoted 

 to a discussion of agglutination of the blood parasite and its behavior toward anti- 

 septics. 



The vitality of the organism of mal de caderas differs greatly according to the 

 medium in which it is grown. Agglutination takes place either in more or less 

 irregular masses, or rarely in the form of a row of beads. In general agglutination 

 occurs rapidly, but the phenomenon may disapjiear after a short period. The author 

 made a number of experiments in inoculating animals with this organism and con- 

 cludes that animals are susceptible to this disease in the following order: White 

 mice, white rats, gray mice, gray rats, dogs, coati, horses, rabbits, cats, guinea pigs, 

 sheep, cattle, pigs, etc. Notes are given on the development of the disease in these 

 various animals and the differences between 7'. rl)iKt.'<suinl and other species (jf this 

 genus are descrilied. 



The relationship bet^veen surra and nagana according to an experiment 

 of Nocard, Valke and Cakuk {('ornjit. Rend. Acad. Sri. J'arix, 137 {1903), N-o. 16, 

 pp. 6/4, 635). — The authors present the details of an experiment carried out l>y 

 Nocard during which it was sliown that a cow imnuiniziMl against nagana w:is as 

 8U8cei)tible to surra as untreated animals. It was found that 3 months after the 

 ai)pearance of st:rra in this animal the Idood containe<l the organism of surra and 

 was very virulent for mice, as shown by inoculation experiment*. 



Erysipelas in horses, Osterwald {Zt.irhr. Veteriniirk. , 15 {1903), No. 7, pp. 319- 

 322). — .\n outbreak of this disease occurred among a troop of cavalry horses and 

 spread with considerable rapidity. Notes are given on a nunilici-of cases observecl
