 presence at the slaughter-houses of the Metro- 

 politan Market, and which we ourselves dis-

 from the Ecole Veterinaire of Alfort, near 

 Paris, whose visit must have been beneficial 

 to England, clearly recognised in an ox 

 which was slaughtered and dissected at the 

 Metropolitan Market, the genuine pustule 

 of typhoid fever. But in most cases, as 

 we shall show, it is the other forms which 

 prevail. 



We make these observations in order to an-
