are at a lofs to account. This, we think, is one of 

 the many errors which crept into practice, when 

 people were ignorant of the nature of the foot ; 

 and has been handed from father to son, each 

 taking it as a fact, and inserting it in his works, 

 without giving the subject a proper degree of 

 attention, 



On Blistering. 



BLISTERING is another powerful stimulant, 

 and is excellent in strains, windgalls, spavins, and 

 sometimes in inveterate grease ; it will likewise be 

 found of great advantage applied to the throat, 

 and under the jaw, in strangles, colds, coughs, &c. 

 and much superior to rowels, when applied over 

 the chest in inflammation of the lungs. The 

 best blister is that which is composed of fresh 

 powdered cantharides and oil, or purified hog's 

 lard. The common proportion is, one part cantha- 

 rides to two of oil or lard ; and it is attended with 

 this advantage, that it never destroys the roots of 

 the hair, which is too frequently the case with those 

 which are composed of sublimate euphorbium and 

 of oil of origanum, which often leave a blemish that 

 can never be removed. By adding or diminishing 

 the quantity of the cantharides, we can make it 

 more or lefs powerful, if required.
