372 TESTS OF TRUE GLANDERS. [BOOK II.

 bloody and white mucus. Finally, if the animal 

 that receives the disorder by infection be previously 

 in a bad state of health, those symptoms are com- 

 plicated and more intense, the chancres are more 

 numerous, the cartilages of the nose become rotten, 

 and the bones likewise, in a shorter time : the

In addition to the preceding tokens for discover-
