Experimental glanders in guinea pigs, M. Nicolle (Ann. Inst. Pasteur, 

 20 il'.UiG). Xos. S, pp. 62')-66J,: !>. i>i>- (>'>^-l'.^><> ; 10. pp. SO 1-S31 ) .—The symptoms 

 and course of slanders in guinea ])igs are described in detail and are compared with 

 those of pseudo-tuberculosis and also with the symptoms which appear in rabbits 

 and other animals when infected with glanders. The supersensitiveness to the 

 glanders bacillus sometimes observed in guinea pigs appears to depend upon the 

 condition of the animal, the previous treatment which it has received, and the 

 virulence of the glanders bacillus used in the experiments. 



The author has shown that it is possihle to innnunize guinea pigs to glanders. 

 There are three methods by which this may be accomplished — by re]»eated in- 

 jections of small doses of dead glanders bacilli, of living bacilli in minute quan- 

 tities, or by a single dose of living bacilli in such quantities as barely to produce 

 an infection. 



Recurrent mange, F. Smith {Vet. Rec, 19 {1906), No. 953, pp. 215, 216).— 

 The .-luthor refers to the difhculties usually experienced in bringing about a 

 complete cure of mange in horses. Most of so-called cases of recurrent mange 

 are due to the fact that the supposed cure in the first instance was only apparent. 



Infectious scratches and verminous aneurism, II. Wucherkr {WcliiiseJir. 

 TicrheUk. ii. ViPhziicht. 50 {1906). No. .l'>, pp. 6H1-6R5). — In a number of young 

 horses the author observed the prevalence of an infectious form of scratches. 

 At first the appetite failed, the flanks became tucked up. and a slight elevation 

 of temperature was observed. After :> or -i days phlegmonous swellings ap- 

 peared about the crown of the hoof and fetlock, follow'ed by an exudation from 

 these points. As a rule, the animals showed marked improvement after about 

 1 week, but in some cases the disease was much more refractory eveu after 

 thorough application of disinfectant powders. 



Notes are also given on cases of verminous aneurism due to emboly and throm- 

 bosis of the anterior mesenteric artery. 



The clinical symptoms of malaria in horses, L. Baruchello {Clin. Vet. 

 [Mihin]. 29 {1906), No. 31, pp. I.'i5-75.'i). — According to the author's observa- 

 tions the fundamental symptoms of malaria in horses are fever, icterus, petechiiP, 

 and hemoglobinuria. All of these symptoms are described in^ considerable detail 

 and notes are given on means of diagnosing between malaria and other diseases 

 with which it nnght be confused. 



The pathology and treatment of pernicious anemia of the horse, .1. N. Ries 

 {Rec. J/r(/. ^ rt.. S3 {1906), No. 19, pp. 611-6^3). — The symptoms of this trouble 

 are described in considerable detail. In many cases the author believes that 

 the chief cause of the disease is excessive infestation with botflies and other 

 parasites. 



A case of spirillosis in the horse, II. J. Stordy {Jour. Com par. Path-, and 

 Titer., 19 {1906). No. 3, pp. 226-22H, figs. 2). — This disease in South Africa may 

 I)e mistaken for dik-kop until after some experience is had. The animal becomes 

 much emaciated and edematous swellings appear on various parts of the body. 

 The most characteristic feature of the disease is the rapid emaciation. 



Surra in Africa, L. Cazalbou {Rev. Gen. MM. Vet., 8 {1906), No. 92, pp. 

 J/01-.'il7, figs. 5). — The geographical distribution of surra in Africa is discussed 

 with mention of the symptoms of the disease in camels and horses. Experi- 

 mental tests proved the possibility of transmitting the disease l)y contact or by 

 inoculation. A number of insects are commonly believed to be instrumental in 

 transmitting the blood ]»arasite, but it is not definitely known whether they are 

 the only agents of transmission or not.
