390 Diseases of Swine. 



called by Dr. Klein, of London, "contagious pneumo- 

 enteritis." 



The third is the malignant epizootic catarrh or influenza, 

 which we have described in the sheep and horse (page 351), 

 who suffer from it, at times severely, especially the former. 

 We shall thus divide the maladies grouped popularly under 

 the name " hog cholera ^^ into — 



1 . Charbon, anthrax or splenic fever. 



2. Contagious pneumo-enteritis. 



3. Epizootic catarrh. 



And we shall endeavor to give such distinguishing traits 

 that they may be recognized one from the other, without 

 difficulty.

 by M. Poche Lubin, in his admirable description of this 

 disease, which he calls charbonneuse typhus ; for although his
