by means of the hog cholera bacillus and a passive ininiuuity by means of the 

 coiTesponding senun. 



The author takes the positicni that B. siiiije.'^tifer must be looked upon as the 

 true cau!-e of hog cholera. It is admitted that the filterable virus is capable of 

 producing hog cholera, but the author considers this virus as being a toxin 

 formed by the interaction of the organism and the hog cholera Ijacillus. and 

 classifies it as an aggi'cssin in the sense of Rail. 



Purulent inflammation of the inner ear in hogs, A. M. Bergmax {Fortschr. 

 Vet. Hi/!/.. // {lixr,), \o. 11. PI). 2'fl-2.'iS, p(jH. S). — The literature relating to this 

 disease in other animals is briefly mentioned. Apparently no cases had pre- 

 viously been recorded in hogs. The author describes a number of cases in 

 which the head vvas twisted to one side as the result of the trouble. A )uicro- 

 scopic examination of the tissues from the inner ear showed that in the 3 cases 

 thus studied the swine plague bacillus and also Barillu.s jii/ogoirs were ])resent. 



The penetration of dead glanders bacilli through the intestinal wall, 

 J. Cantacuzexe {('ojii/jt. Rend. Sac. Biol. [Paris], 61 [1906). To. 31. pp. 

 61S-62'i). — Dead glanders bacilli were found capable of passing through the 

 intestinal epithelium. A certain portion of the bacilli after passing through 

 the epithelium were captured by phagocytes, but some of them succeeded in 

 escaping and entering the lymph system. The ordinary intestinal bacteria 

 associated with the dead glanders bacilli were not able to pass by the phagocytes. 



Some remarks on equine biliary fever in India, C. H. H. Jolliffe {Jour. 

 Tro/t. Vet. tici., 2 {1901), Ao. 1, pp. 51-66). — Equine biliary fever prevails quite 

 widely in various parts of India and at times causes serious losse;; among 

 horses. Notes are given on the symptoms and pathology of these disea.^es, dif- 

 ferential diagnosis, and treatment. Thus far quinin has given the best results 

 in the treatment of the disease, but a really satisfactory treatment has not been 

 devised. 



The pathological anatomy of the Borna horse disease, H. Oppenheim and 

 K. Ostertag {Ztsdir. Iiifcktioii.shnnih-. ii. Hug. Uaustiere, 2 {1907), Xo. 2-3, 

 pp. l-'iS-lol',. fiffs. 3). — The pathological lesion in this disease may be character- 

 ized as a not diffuse but localized meningocephalitis of an acute but nonpurulent 

 nature. The clinical symptoms and pathological findings are described in detail. 



The Trypanosoma equiperdum in Canada, J. G, Rutherford {Yet. Rec, 

 19 {190'i), Xo. 9,'i2. p. 710). — It is announced that the protozoan parasite of 

 dourine'has been isolated from a case of this disease in Canada and has been 

 recovered from another horse inoculated with material from the first case. 



The treatment of infectious cerebro-spinal meningitis of horses, E. Diem 

 (Wchnschr. TierhrilL: ii. Viehzucht, .51 {1907), Ao. 16, pp. 301-303).— In the 

 region about Burghausen it is stated that this disease is quite prevalent. The 

 author has had occasion to treat numerous cases. The treatment recommended 

 is essentially as follows : The horses are kept in well-ventilated, cool stalls and 

 allowed to feed only on grass or hay. An abundant supply of water is provided 

 to which certain mineral salts may be added. On 3 days in succession injec- 

 tions are made of bichlorid of mercury in doses of 0.1 gm. in 10 cc. of water to 

 which a little common salt has been added. This method has been tested for I 

 years and in nearly all cases a complete recovery has been brought about. 



Inflammatory tumors caused by spiroptera in the horse, Weinberg {Cotiipt. 

 Rend. S(j(:. Biol. [I'tnis], 62 {}'.>(i7). \o. 7. /)/>. 2S7-2SD). — A number of nematode 

 worms are known to live as parasites in the stomach of the hoi"se and occasion- 

 ally they bury themselves in the mucous memlirane in such a manner as to i)ro- 

 duce tumors, with more or less serious effects. This is especially the case with 

 spiroptera. During the formation of the tumors thus produced opjiortunity is 

 given for infection with pathogenic bacteria.
