an extent that it looks as if the horse were salivated. 

 The legs soon swell, or become rounded, or filled as 

 they are often called. The swellings are not inflamma- 

 tory, nor painful; they contain lymph, or plastic mat- 

 ter fi-om the blood, which disappears as it came, when 

 the strength of the horse gets up again, and the disease

 atmospheric influence, may be either electric, a poison, or 

 a chemical element, capable of altering or changing the 

 various parts or portions of the body most exposed to its 

 subtle influences. However, this disease, as before stated,

 colder air or gas given forth from the thawing process, than 

 the animal is breathiag a few feet higher up from the 

 ground? This was one of the points entering into the 

 celebrated controversy between myself and the distiii-
