CAUSTIC SALVE AND WASH. 

 VI. 



These are made of the common caustic potash of com- 

 merce. The wash is simply a strong solution of lye of pot- 

 ash and water. 



Use. — For the cure of warts of different kinds, the lye 

 is to be applied in the morning, then washed off in the even- 

 ing, and the application repeated. This is to be continued 

 until the wart is driven away. In the treatment of a blood 

 wart, the corrosive liniment should follow the use of the pot- 

 ash, to destroy the roots of the wart and heal the sore. If a 

 seed wart, grease the place after using the potash, and let it 

 go. Care must be taken, in using caustic potash, not to let 

 it run on other parts of the skin than that under tteatment, 

 as it will invariably remove the hair and cause a sore. This 

 may be prevented by spreading a coat of grease below the 

 wart on the skin. 



The caustic salve is made by mixing finely-pulverized 

 charcoal with the lye. This is used in the same manner as 

 the wash, but it is to be preferred, because there is no danger 

 of its running. 



PROP. DALE S PERSIAN HORSE AND CATTLE POWDERS. 

 VII. 



A very excellent tonic and alterative, to be used according 

 to directions given in different parts of this work. 



NITRIC ACID. 

 VIII. 



Nitric acid is also used to destroy warts, but must be 

 handled with extreme caution. A piece of leather or thick 

 pasteboard, with a hole cut in it large enough to allow the 

 top or crown of the wart to pass through, is first placed over 

 the wart, and then a very little of the acid carefully applied 

 with a very small brush or a little mop. The parts below 

 the wart should be well greased with tallow to prevent the 

 corrosive action of the acid which might trickle down. The 

 application of the acid should be made every twelve hours,
