small intestine of swine infested with Evliiuor/ii/iicltus glgus, it was founil that 

 this parasite by attacliing itself to the wall of the intestine may destroy in a 

 met-Lianical manner the mncous^ submucons, and even the muscular layer of the 

 intestinal wall without producing any inflammation. The eosinophilous cells 

 found near the point of attachment of the ])arasitic wrms are apparently not 

 attractetl there by the presence of the parasites. E. gigas may produce lesions 

 in which pathogenic bacteria find entrance to the host, causing infectious or 

 necrotic enteritis. 



Swine erysipelas, E. Cesari (Hyg. Viande et Lait, 1 {1907), No. 12, pp. 344- 

 551). — A considerable number of cases are cited in which swine erysipelas has 

 l)een transmitted to man. The characteristic symptoms of the disease as 

 observed in meat inspection ai"e briefly outlined. The bacilli are not destroyed 

 by the ordinary method of preserving hams until after at least 6 months, and 

 the author recommends that pork affected with this disease should not be 

 admitted for human consumption until it has at least been sterilizeil. 



The occurrence of the bacilli of swine erysipelas on the intestinal mucous 

 membrane and in the tonsils in healthy hogs, W. Pitt (Centbl. Bakt. [etc.], 

 1. Aht., Orig., .'i5 (JHOJ), Xos. 1. pp. 33-37; 2, pp. 111-121).— 1-a an examination 

 of the intestinal mucous membrane in 66, and of tonsils in 50, healthy hogs, 

 undoubted bacilli of swine erysipelas were found in 26 and 28 cases, respectively. 

 The author concludes that the bacilli of swine erysipelas may occur in nearly 

 50 per cent of healthy hogs a)id that, therefore, prophylactic measures, such 

 as have been commonly advocated, are of low value. It is, therefore, recom- 

 mended that protective vaccination be adopted as the only reliable means of 

 controlling this disease. 



The behavior of white blood corpuscles in common diseases of the horse, 

 E. Fraxke (Monatsh. PraJct. Tierheilk., 19 {1907), No. 2-3, pp. 98-120).— The 

 variations which occur in the relative proportions of red blood corpuscles and 

 the various kinds of leucocytes are presented in a detailed manner as observed 

 in cases of pneumonia, influenza, petechial fever, tetanus, etc. Attention is 

 called to the fact that in order to obtain reliable results from the examination 

 of the blood the determination of the relative percentages of the different kinds 

 of leucocytes must be made immediately after the blood is withdrawn. 



The behavior of red blood corpuscles in surgical diseases of the horse, par- 

 ticularly in purulent inflammations, A. Gasse {Monatt<h. Prakt. Tierheilk., 

 19 (1907), No. 2-3, pp. .'i9-98, pi. 1). — The content of red l)lood corpuscles in 

 the blood is only slightly affected by the sex of the animal. The white blood 

 corpuscles vary more extensively. The relative percentages of various kinds of 

 white blood corpuscles in normal- blood are given in a tabular form. In cases 

 of inirulent inflammation a hyperleucocj'tosis need not be considered especially 

 serious if the relative proportion of the different kinds of leucocytes is not 

 greatly disturbetl. If, on the other hand, there is considerable increase in the 

 number of neutrophil cells and a diminution in the number of lymphocytes, 

 prognosis is quite unfavorable. The basophil cells appear in nearly all cases 

 to vary in the same manner as the eosinophils. 



Studies on glanders, V. Galtier {Jour. Med. Vet. et Zootech., 59 (1908), Jan., 

 Vl>. 1-5). — Glanders bacilli in small pieces of infected tissue are rendered en- 

 tirely sterile by submerging in glycerin for a period of 12 days. The attenua- 

 tion of the bacilli- progresses gradually during this period. Dead glanders 

 bacilli are toxic, and in the author's experiments they were shown to possess 

 considerable toxicity after their virulence had entirely disappeared. No satis- 

 factory results were obtained in immunizing dogs and guinea pigs against 

 glanders.
