cedematous part, the appearance which presents itself in the 

 case of anthrax is moist, b'right and gelatinous, and light red. 

 In the case of charbon, however, the cedematous part on 

 incision presents a dull dark red, almost black, appearance. 

 The cedematous part in the case of anthrax also is redder 

 than in the natural state ; but the difference in colour in the 

 two diseases is most characteristic. 



(3). Both charbon and anthrax are virulent for susceptible 

 animals j but charbon is quicker in its effect, death tak- 

 ing place within 24 hours ; whereas, in the case of anthrax, 

 oftener after 36 hours, and usually, if the animal lingers for 

 more than a week, recovery takes place. Two guinea-pigs 

 inoculated at the same time by M. Arloing, for demonstrat- 

 ing the difference between the two diseases, were found two 

 days afterwards, one dead and ready dissected, and the other 

 (vt2., that inoculated with anthrax virus) still alive. 



(4). The disease in the one case is caused by a non-motile 

 bacillus, viz., in the case of anthrax, and in the other, t. e., in 

 the case of charbon, by a bacterium, which is a shorter orga- 

 nism, which never forms chains as bacilli do. 



(5). The organisms of disease are found in the case of 

 anthrax all over the body, more or less in every tissue, but 

 more particularly in the spleen, the heart, and the liver. In 

 the case of charbon they are found only in the cedematous 

 part, and they are invariably localized. 



(6). Swelling of the glands of the neck is invariably 

 present in the case of charbon when it arises spontaneously, 

 and only sometimes in the case of anthrax. So neck swel- 

 ling must not be regarded as the diagnostic symptom in the 

 case of gloss-anthrax or charbon. 



(7). A crepitating sound of the cedematous part is always 

 present in the case of charbon, never in the case of 

 anthrax. 



(8). Spores are formed in the charbon organism (named 

 by M. Arloing, Bacterium Chauveau) in the body of the animal
