as the only criterion for diagno^i^. It is considered, however, that the presence of 

 glycosuria is of great importance in the diagnosis of rabies when observed in connec- 

 tion with other suspicious symptoms. In dogs it is believed that the demonstration 

 of glycosuria may be considered an important element in diagnosis. In herbivorous 

 animals, such as rabbits, goats, and asses, the condition of glycosuria was found 

 present in all cases of rabies, and this one symptom was therefore considered suffi- 

 cient for determining the diagnoses of these animals. In herbivorous animals glyco- 

 suria may be recognized, not <inly after death, but (hiring the progress of the disease. 



Antirabies immunization by means of intravascular injections of rabies 

 virus, V. Kkasmitski {Ann. Inst. Pasteur, 16 {1902), No. 6, pp. 393-417). — An 

 extensive series of experiments was conducted by the author on experimental animals, 

 antl these results are compared with phenomena observed during the progress of the 

 disease in man and domesticated animals. As the result of the author's experiments 

 it is concluded that intravenous injections of rabies virus are not dangerous, provided 

 the virus is administered in a filtered, diluted emulsion, the emulsion to be previ- 

 ously heated to a temperature of 37° C. and injected slowly. By means of intravenous 

 injection it is possible to render the animals refractory to rabies in a very short 

 period, and the immunity thus produced appears to be more lasting and certain than 

 that produced by other methods of vaccination. Intravenous injections made on 

 rabbits sometimes prevented the development of the disease, even after intracranial 

 inoculation of rabies virus. Rabid nerve virus rendered nonvirulent by any attenu- 

 ating reagent does not possess an immunizing jiower. It may be used, however, as 

 a vaccine, and when administered repeatedly in increasing doses renders animals less 

 susceptible to the disease. 



A ne-w infectious disease in domesticated animals, A. Aujeszky {C'enibl. 

 Bait. u. Far., 1. Abt., 32 {1902), Xo. 5, Urig., pp. 353-357). — During experimental 

 investigations for the purpose of confirming a diagnosis on animals susi^ected of 

 rabies a virus was isolated, which produced symptoms somewhat resembling those 

 of rabies. It was found by a series of experiments that this virus was in the nature 

 of a toxin, but all bacteriological tests were negative. An inflammatory condition 

 developed at the point of inoculation within 36 to 48 hours, and the symptoms of 

 the disease progressed rapidly from this time until the animal died, a few hours later. 

 While the general symptoms of the disease resemble those of rabies, it can not be 

 confused with the latter disease for the reason that the course of the disease is so 

 rapid, the usual period being from 6 to 10 hours. The pathological alterations which 

 are observed in carcasses of animals dead of the disease include hypera?mia, minute 

 hemorrhages in the internal organs and central nervous system, and distention of 

 the alimentary tract. 



Meningitis in dogs, C. Cadeac [Jour. Med. Vet. et Zootech., 5. ser., 6 {1902), Apr., 

 pp. 193-196). — The symptoms of this disease are said to be not very uniform. The 

 cause of the disease is usually found in injuries to the eye and ear; the membranes 

 of the brain and spinal cord may later show pathological lesions, as well as the eye 

 and internal ear. The Eustachian tube may be filled with caseous or calcerous pus, 

 and its Avails may be thickened and much injected with blood. 



Eczema rubrum of the dog, H. Bar {Schweiz. Arch. Tierh., 44 {1902), Nos. 1, 

 pp. 1-13; 2, pp. 49-68, pis. 2). — The literature of this subject is reviewed in a critical 

 manner in connection with a bibliography of 20 titles. The author found during his 

 investigations that eczema ruljrum is in no sense a developmental stage of another 

 form of eruption, but is a specific disease of a parasitic nature due to a micrococcus 

 of relatively slight virulence and resisting power. Apparently infection takes place 

 in skin wounds. Not all dogs are susceptible to the disease. In addition to a certain 

 predisposition, a long coat of hair seems lo favor infection.
