5th. In the " yellows," give purging drinks, and tonics. 

 6th. Whenever external inflammation is great, purging 

 medicines must always be used. 



SETONS, 



Are useful in various cases, such as black-leg, hoose, 

 joint-evil. Setons cause a discharge of diseased matter, 

 and thus relieve the system of the cause of disease ; and 

 also relieve the overloaded vessels in the neighborhood 

 of the seat of inflammation. 



MODE OF INSERTING A SETON. 



A seton may be made of tow and horse-hair, braided 

 together. This is the best kind of seton. It will answer, 

 however, to use a strip of leather, or a small cord. The 

 length should be about ten inches. Before inserting it, 

 it. should be dipped in oil of turpentine. With a seton 

 needle, run it into the upper edge of the dewlap, and out 

 at the lower edge. Then tie a large strong knot at both 

 ends of the seton. In a day or two the matter will begin 

 to run. After it begins to run, the cord should be drawn 

 backward and forward every day, to increase the dis- 

 charge. 



Sometimes it is necessary to create a discharge at 

 once. This can be done by dipping the seton in the fol- 

 lowing preparation : 



Yellow basilicon, one ounce ; powdered cantharides, 

 (Spanish flies) three drachms ; spirit of turpentine, two 

 fluid drachms. 



We shall now proceed to notice a few of the more com- 

 mon diseases of horned cattle, sheep, and swine ; with fa- 

 miliar instructions for their prevention and cure.
