716 EXPERIMENT STATION RECORD. 



Detailed notes are given on the gross and microscopic anatomy observed in the 

 different diseases which the author .studied in the swine udder. The 4 cases of 

 mammary tuberculosis observed in hogs were due to the generalization of the disease 

 as a result of the translocation of the bacteria through the circulating blood. The 

 chief contingent of the mammary diseases in hogs is actinomycosis, and this is 

 explained as due to the unusually frequent opportunities offered for the organism of 

 actinomycosis to enter hogs through skin wounds. 



Mai de caderas in domesticated and wild animals, M. Elmassian and E. 

 Migome (Ann. Ji/xt. Pasteur, 18 (1904), No. 9, pp. 587-589). — On a cattle ranch in 

 Paraguay badly infested with capibaras, hunting expeditions were organized for the 

 purpose of destroying these pests. It was noted, however, that on every occasion of 

 this sort the dogs which killed and ate the capibaras became affected with mal de 

 caderas and died. 



The same disease broke out also among the horses used for bunting. Laboratory 

 experiments and miscroscopic tests showed the presence of the blood parasite of mal 

 de caderas in all cases. Itappears, therefore, that the capibara is frequently infected 

 with the organism of mal de caderas, and is capable of transmitting the disease to* 

 domesticated animals although itself suffering only a mild form of the disease. 



Infectious abortion in horses, P. Crest a et .w.. ( Bol. f~Jji<'- Min. Agr., Ind. e < '<>in. 

 [Rom?], 5 (1904), No. .', pp. 180-182). — This is a brief report of a commission 

 appointed for the purpose of investigating this disease. It is recommended that in 

 all cases of abortion the fetus be destroyed and all contaminated objects be disin- 

 fected with a 5 per cent solution of corrosive sublimate. Aborting mares should be 

 isolated and subjected to proper antiseptic treatment. 



Thrombosis of the posterior aorta and of the iliac arteries in horses, F. 

 Supfkan (Rev. Vet. [Toulouse'], .."> (1904), No. m, pp. >;.',? -664). —The symptoms of 

 tins disease are described and detailed clinical notes are given on the case which came 

 under the author's observations. The disease resulted fatally and pathological 

 lesions as shown at a post-mortem examination are described. 



Reports from the Berlin medicinal clinic, E. Frohner (Monatsh. Prakt. Tierh., 

 16 (1904), No. l,pp. 40-47). — In experiments undertaken for the purpose of testing 

 the value of strophanthin in the treatment of pneumonia of horses it was found that 

 this drug produces a necrosis and is not suitable for use in the treatment of pneu- 

 monia either in a pure form or in the form of a tincture. Brief notes are also given on 

 the value of thoracic puncture in the treatment of pneumonia. 



Pathological report on a case of rabies in a woman, J. R. Mohler ( 1 '. S. 

 Dept. Agr., Bureau of Animal Industry Rpt. 1903, /ij>. 54-60, pi. 1; C'irc. 54, pp. 54-60, 

 pi. 1). — Notes are given on a case of rabies in a woman who died 21 days after being 

 bitten by a rabid dog. Portions of the medulla oblongata, upper part of the spinal 

 cord, and right plexiform ganglion of the vagus nerve were removed and examined 

 for the presence of the lesions described by Van Gehuchten and Nelis. 



The principal change observed was an extensive proliferation of the endothelial 

 cells of the capsule. An infiltration of the leucocytes was also noted. Inoculation 

 experiments were made with an emulsion from the medulla oblongata. All of the 

 rabbits which were inoculated with this material died with typical cases of rabies. 

 The lesions found by a histological examination of the plexiform ganglion of the 

 vagus nerve were such as has been considered typical of rabies. 



The passage of rabies virus through Berkefeld filters N and W, P. Rem- 

 lixger (Compt. Rend. Soc. Biol. [Paris'], 56 (1904), No. 4, pp. 150, 151).— The author 

 had already demonstrated that rabies virus may pass through the Berkefeld filter Y. 

 In these experiments it is also found to pass through Berkefeld filters N' and W. 

 Animals inoculated with filtered virus develop rabies after an incubation period of 

 h» or 11 davs.
