bone of the leg, and even the blistering liquid is 

 improper when this symptom is highly prevalent. 

 Rather let the heat subside, or assist it in doing so 

 by means of Goulard's extract, diluted with water, 

 frequently applied. When this has reduced the 

 heat, employ the following 



Liquid Blister. 



Cantharides pulverised, 4 drachms. 

 Mix with sweet oil to the consistence of treacle., 

 and apply the same twice during the day ; thus, 

 — Let the hair be clipped off close from the part, 

 and all round the leg, and the blister well rubbed 

 with the hand (covered), for five or ten minutes. 

 If this does not cause further swelling and the 

 discharge be of a clammy nature, a third application 

 of the liquid blister becomes necessary. After a 

 day has elapsed, dress two or three days with hogs' 

 lard, and the patient may be walked about, to get 

 rid of the stiffness. It may be proper, after this, 

 farther to reduce the heat by more applications of 

 the Goulard's extract, as above. 



Shoeing is supposed to occasion splents some- 

 times, it being the practice with most smiths to 

 make the inner heel of their shoes thinner than 

 the outer ; and the inner heel being also lower 

 than the outer, occasions the splent bone to re- 

 ceive the concussion more sharply than the outer 

 one; for, as was before observed, splents oftener 

 occur on the inside of the leg than on any other 

 part of it.
