928 EXPERIMENT STATION RECOKD. 



subject and gives the results of numerous experiments carried out by veterinarians 

 in different parts of Germany with regard to the curative power of lecithin in cases 

 of cerebro-spinal meningitis. The number of injections of lecithin used varied from 

 1 to 11. This remedy has been used for the past 3 years to a considerable extent, 

 but the results are not sufficiently satisfactory to consider lecithin as a specific against 

 this disease. 



Tsetse-fly disease among mules in the Sudan, A. S. Hbad (Jour. ('amp. Path. 

 ami 77/(7-., 17 (1904), No. 3, pp. 206-208, fig. 1). — Notes are given on the symptoms, 

 post-mortem appearance, and etiology of this disease, especially as observed in mules. 



Evolution of the Trypanosoma evansi, J. D. E. Holmes (Jour. Comp. Path, 

 and 77/(7-., 11 | 1904 • No. S,pp. 210-114, ph. 2). — The author presents a critical review 

 of the bacteriological methods proposed by different authors for studying this 

 organism and related species of parasites. Notes are also given on the appearance 

 of the organism in its different stages of development. 



Perforation of the small intestines in horses by Ascaridae, Franc ke 

 (Forlschr. Vet. Hyg., 2 (1904), No. 7, pp. 185-188, figs. 3). — The literature relating 

 to Ascaris megalocephala is critically reviewed, together with detailed notes on the 

 pathological anatomy observed in a fatal case of infestation by this worm in which 

 the walls of the small intestine were perforated. Numerous specimens of this worm 

 were observed in the intestines and in the body cavity. 



Glanders and farcy, Flintoff (Orange River Colony, Dept. Agr., Farmer* />'///. 1, 

 pp. 8). — The symptoms, methods of contagion, development, and post-mortem 

 appearance of this disease are described, and references made to the government 

 regulations regarding glanders. 



Clinical notes, J. Marek (Ztschr. Thiermed., 8 (1904), No. 6, pp. 434-439).— 

 Notes are given on the occurrence of various forms of colic, intestinal obstructions, 

 and similar troubles in horses, with an account of the most successful methods of 

 treating these diseases. 



Three common diseases affecting the horse's foot, H. C. Wilkie (New Zealand 

 Dept. Agr., Die. Vet. Sri., Bui. 8, pp. 11). — Notes are given on the symptoms, patho- 

 logical anatomy, and treatment of laminitis, sand crack, and navicular disease. 



Experimental investigation of rabies, E. Bertarelli and G. Volpino (Centbl. 

 Bakt. u. Par., 1. Abt., Orig., 37 (1904), No. 1, pp. 51-58). — The filtration of rabies 

 virus was studied with especial reference to its attenuation by this means. It was 

 found that rabies virus could be passed through a Berkefeld filter under a pressure 

 of 3 or more atmospheres, but that not all of the virus could be forced through the 

 filter. The material on the filter and in the filter always retained a certain degree 

 of virulence. The authors conclude, therefore, that the organism of rabies must exist 

 in different forms, some of which are of sufficient diameter to prevent their passage 

 through a Berkefeld filter. 



The means by which rabies virus reaches the salivary glands in dogs, 

 E. Bertarelli (Centbl. Bakt. u. Par., 1. Abt., Orig., 37 (1904), No. 2, pp. 213-221).— 

 In accounting for the fact that rabies virus is found in considerable quantity in the 

 salivary glands of dogs, 3 courses have been assumed as a possible means by which 

 the virus reaches this position, viz, lymphatic system, blood circulation, and the 

 nerves. The author's experiments were carried out on healthy young dogs, which 

 were inoculated with rabies virus of known virulence. The technique of the experi- 

 ments was arranged so that only one of the organic systems mentioned could possibly 

 be concerned in the localization of the virus in the salivary glands. This was found 

 to be easy of accomplishment by merely shutting off the blood supply or lymphatic 

 supply or by severing the nerves which are distributed in the gland. 



As a result of these experiments it was shown conclusively that virus of rabies 

 reaches the submaxillary and probably other salivary glands only through the medium
