increased secretions in these organs, there is danger of 

 injury and debility from over-action. [See Diseases of 

 the Urinary Organs in Horses.] 



Diuretics are used more in the treatment of horses, 

 than m cattle practice. The following are diuretics ; — 

 rosin, turpentine, juniper, gin, saltpetre, honey, potash, 

 digitalis, squills, tobacco, and cream of tartar. Many 

 kinds of food have a diuretic effect, such as apples, 

 pumpkins, roots generally, green corn-stalks, and most 

 kinds of green herbage, at first. [For the principal diu- 

 retics in use, and the dose, see this subject under Horses 

 and Cattle. For sheep, use the same as for cattle, only 

 one eighth part as much for a dose.] 



The following is good, as a general diuretic drink : — 

 Powdered sahpetre, two drachms ; powdered rosin, half 

 ounce ; ginger, two drachms ; mix well together in a lit- 

 tle molasses, and give in warm gruel. 



SETON OR ROWEL. 



A seton is a piece of leather, cord, coarse tape, braided 

 horse-hair, or tow, passed, by means of a large needle, 

 through the base of an ulcer or abscess, such as ulcer- 

 ated poll evil, fistula, &c., to drain ofi" the acrid and 

 irritant humors ; or they are inserted between the skin 

 and muscular, or other parts beneath, in a sound part, 

 to create an artificial issue, and make a general improve- 

 ment in the whole system, or relieve a neighboring 

 afiection. 



Setons are inserted in the breast of horses, and in the 

 dewlap of cattle, in case of general inflammation, which 

 is abated by a discharge of matter. They are also good 

 m case of inward strains, and for swellings that cannot 

 be dissolved. When the blood is in a bad state, a seton 

 will draw off" the foul humors, and thus improve the 

 condition of the blood. 



In cases of local complaints, this general issue will 

 draw superfluous humors from all parts of the body, and 

 discharge them, and thus relieve the complaint. When 

 the local affection is very severe, and wiU not yield to 

 other treatment, a seton may be inserted near it, say
