688 EXPERIMENT STATION RECORD. 



An outbreak of epizootic gastro-enteritis in dogs, II. Sumner (Vet. Rec, 

 20 (1907), No. 99.'i, pp. 55-58). — The disease is less common than distempei-. It 

 affects all ages and breeds of dogs. The pathogenic organism belongs to the 

 pasteurella group. The mortality varies from 15 to 75 per cent and the course 

 of the disease from 1 to 28 days. The symptoms include intestinal pain, con- 

 traction of the abdominal muscles, violent vomiting, and bloody diarrhea. The 

 mucous lining of the stomach shows an intense inflammation, and in some cases 

 the brain membranes are hyperemic. Treatment is of no avail in acute cases. 

 In the chronic form ice packs about the head and the administration of arsenical 

 liquor and bromid of potash gave good results. 



Sublymphatic leukemia in dogs, A. Jaeger (Berlin. TierdrzU. WclDisclir., 

 1907, No. 30, pp. 563-566). — In cases of this disease the cervical glands become 

 enlarged, but no other external symptoms are to be observed. The ratio of 

 white to red blood corpuscles is 1 : 300, On post-mortem examination all the 

 lymphatic glands are found to be enlarged. The spleen and liver are but 

 slightly changed in size, and the bone marrow is unusually soft and contains an 

 enormous number of lymph cells. The author draws a distinction between 

 granular and lymphatic leukemia. 



Rabies studies, C. Fermi, G. Tizzoni, and A. Bongiovanni (Centhl. Bakt. 

 \ctc.], 1. Aht., Grig.. J,Jf (1907), No. 1, pp. 23-32).— Filtration of rabies virus 

 through a Swedish filter of 1 to 4 layers prolonged the jieriod of incubation in 

 animals inoculated with the filti'ate, and one rabbit did not become infected at 

 all. Bacillus pyocyaneus, B. prodigiosus, spores of fungi, and amoeba are also 

 able to pass through several layers of the filtei. 



Experiments with 43 laboratory animals showed that the cerebro-spinal fluid 

 of animals dead of rabies is not virulent when it is obtained entirely free from 

 nerve tissue. Neither the saliva nor salivary glantls were found to be virulent 

 in any case. 



In order to decompose rabies virus with salts of radium it is necessary to 

 use aluminum tubes rather than glass. 



The virulence of the saliva and salivary glands of rabid animals, C. Fermi 

 (Arch. Farmacol. Sper. c 8ci. Aff., 6 (1907), No. 6, pp. 327-331).— The saliva 

 of dogs, rabbits, rats, etc., dead of rabies did not always prove to be virulent. 

 The author did not succeed in transmitting rabies to mice by the bites of rabid 

 rats or dogs. Mice also proved to be unsuscei)tible to the saliva of rabid dogs. 



Histological changes in pseudo-membranous enteritis in cats, E. Schmul 

 (Arch. Wiss. u. Pnih-f. Tierheilk., 33 (1907), No. .',-5, pp. Ji'i5-'i60).—\\\ the 

 course of this disease the intestinal follicles become conti'acted and infiltrated, 

 and finally undergo necrosis, the walls of the intestines become thickened, rigid, 

 and transparent, and hyperemia is observed in the liver and kidneys. 



Polyneuritis in fowls, J. Marek (Dcut. Tierdrztl. Wchnschr., 15 (1907), No. 

 30, pp. Jil7-Ji21, figs. 2). — A nervous disease of fowls resembling beri-beri' is 

 known in India. The author describes four cases of polyneuritis in roosters 

 in Budapest. The chief synii)toni is a progressive i)aralysis of the legs. The 

 nerves sui)plying the affected parts are greatly changed, often showing an 

 almost complete disappearance of the nerve fibers. The cause of the disease is 

 unknown. 



In ti'eating polyneuritis of fowls some benefit may be derived from massage 

 of affected parts, and from the administration of sodium salicylate and bone 

 meal. 



Septicemia of fowls caused by coli bacillus, L. Claussen (Ztschr. Infections- 

 krank. u. Hyg. Hatistiere, 3 (1907), No. 1-2, pp. 69-91}, pi. i).— Coli bacilli 

 in the intestines of healthy fowls possess the power of becoming virulent under
