 nutritious and readily digestible as well as of a laxative 

 character. The animal should be placed in a large, airy

 be able to exercise himself to a certain extent.

 is also very commonly known as cow-pox, is one of 

 frequent occurrence in every quarter of the globe; as a

 an eruptive pustular disease, and may occur in connection 

 with any part of the body, but is usually confined to the 

 udder. In England it has been observed to occur with
