THE IMPROVED ART OF FARRIERY. 159 



parts of the bone become, when detached, extraneous 

 substances, and must be brought away before the 

 wound can thoroughly heal. Hence it sometimes 

 happens that the surface of the wound hee^ls whilst 

 the bottom or internal parts are unsound, owing to 

 the circumstance of the bone not having exfoliated, 

 and the irritation being still kept up, a fresh degree 

 of inflammation ensues, and the wound suppurates and 

 breaks out again. 



" In this case, (and in this only), the mouth of the 

 wound may be kept open by the introduction of tents ; 

 and if the abscess has not a sound, healthy appearance, 

 such caustic applications may be used as will destroy 

 the diseased surface and produce a healthy action in 

 the part, which is always manifested by red granula- 

 tions, and the secretion of pure white matter of a proper 

 consistency. 



"It is necessary to observe that probing wounds 

 should never be carried to excess, indeed it should be 

 avoided as much as possible ; and at all times the 

 finger is the best instrument to be used for that pur- 

 pose. 



" The mouth is subject to ulcers from many causes, 

 as the use of a rusty bit, decayed or broken teetli, &c. 

 Apply— 



Alum - ^ . - - 4 drachms. 

 Water - - _ - 1 pint, 



mixed. Or — 



Tincture of Myrrh - - 1 ounce, 



Water - - - - 1 ounce, 



mixed. 



" Either of these will dissipate the ulcerous ap- 

 pearance. 



" A httle internal cooling medicine is necessary 

 if inflammation accompanies ulcer in the mouth.
