388 PRINCIPLES OF VETERINARY SURGERY 



Standpoint of its symptoms and pathological anatomy. To 

 him the vitiation of the exuded blood exposed to the air 

 was the origin of the disease. He repeated the experiments 

 of Bartholemy and Ddpuy and reproduced the affection with 

 its essential features. Renault was a precursor, as his idea 

 of the disease has proven very accurate. "It is the entire 

 economy," he says, "that is penetrated with poison, which 

 exhibits its presence and effects by the following symptoms, 

 etc." 



For a long time the etiology of the disease remained hid- 

 den in profound obscurity. Different hypotheses as to its na- 

 ture were advanced, but all were insufficient until the bac- 

 teriological era at last revealed the secret of the affliction. 

 Some physicians, — Nepveu, Bottini and Samuel, — found mi- 

 crobian agents in the blood and in the liquid of the lesions. 

 In 1877 Pasteur brought to light the role of the septic vibrio 

 in a case of animal septicaemia, and Morand attributed gas- 

 eous septicaemia of man to this agent. Davaine, Coze, Feltz, 

 Chauveau and Arloing, above all, proved experimentally the 

 identity of the septic vibrio of Pasteur with the microbe of 

 gaseous septicaemia. Henceforth, gaseous septicaemia consti- 

 tutes a well-defined morbid entity and numerous recent re- 

 searches have confirmed the previous deductions. Nearly 

 everyone recognizes the action of Pasteur's microbe. The 

 German school alone, with E. Franckel, disputes the iden- 

 tity of the vibrio and the microbe of gangrenous septicaemia, 

 but up to the present time, this school has not advanced any 

 fact that absolutely proves the doctrine it defends. 



SUSCEPTIBLE ANIMALS.— Most all of the domestic 

 species are liable to succumb from the inoculation of the 

 septic vibrio. Cornevin, who has studied the receptivity of 

 the different domestic species, has classed them according 

 to their susceptibility in the following manner : 

 In the first rank — Horse ; donkey.
