GENERAL DISEASES. 123 



serrated nor swollen, as in glanders. Further, the ulcers 

 were superficial, rarely reaching as deep as the subcutis, 

 and they readily healed after the sixth day. They were 

 isolated and independent of the course of the lymphatics, 

 and when the brownish scab was removed they presented 

 a whitish granular surface. The disease only lasted from 

 twelve to fourteen days, and ran through a whole stable in 

 three weeks or so. 



This disease, therefore, differs from glanders in the cha- 

 racter, distribution and rapidity of the healing of the 

 ulcerations; in the absence of inflammation of the ab- 

 sorbents j in the absence of ulcerations on the Schneiderian 

 membrane, and finally in the rapid course of the disease, 

 in) the shortness of its latent period, and in the rapidity 

 with which it spreads from one animal to another. 



Stomatitis pustulosa also resembles variola equina, but it 

 cannot be regarded as true equine variola.
