sore does not heal too fast. Should this be the case 

 put blue stone, powdered, upon the plaster once or 

 twice, or merely touch it with lunar caustic as often. — 

 Sometimes the callosity does not come off of itself, tho' 

 the edges rise up : it is then to be taken away by force, 

 separating it from the living parts with the knife. The 

 small portion of blood that comes away with it does no 

 harm, but the contrary. If, however, any one objects 

 to the knife, or doubts his skill in this operation, mercu- 

 rial ointment will effect the same end, as follows : 



Ointment for Sit fast. — Oil of tm-pentine, 10 ounces; blue oint- 

 ment, 8 ounces; gum ammoniacum, 4 ounces. Mix and apply to 

 these and all hai'd tumors. 



QUITTOR is a disease of the foot, at the coronet, 

 but is so decidedly fistulous, that I choose to treat of it 

 in this place, rather than in the chapter devoted to the 

 foot in general. It is caused by a tread which the horse 

 inflicts on himself, for the most part, seeing that it gen- 

 erally occurs on the inside of the foot. This tread or 

 bruise may either be inflicted upon the coronet, or lower 

 down, by over-reaching, or even at the sole ; by taking 

 up a stone or other hard substance ; also by a prick or 

 blow in shoeing. A quitter is also sometimes occa- 

 sioned by gravel working up into an aperture left by an 

 old nail, actinii upon the sensible laminatetl .«;ubstance, 

 separating it from the insensible, leaving a cavity from 

 the aperture up to the coronet, where it lodges, inflames, 

 and produces abscess, which is very troublesome and 

 difficult to cure. 



Cure. — The sore is always very small, but admits of 

 a probe being introduced, by which the extent of the 

 evil may be ascertained, and this is generally very ex- 

 tensive and ruinous, according to the time it may have 

 been allowed to make head. The probe will pass read- 

 ily forward and backward to the whole course of the dis- 

 ease, and sometimes it will be found to have penetrated 

 to the cofiin bone, every where forming sinuses or pipes, 

 as in fistula of the withers before described. In slight 

 cases, those which are found not to have penetrated 

 deep, the simple application of a wash will prove suffi- 

 cient, and may be employed in this manner : Dissolve 

 blue vitrol in water, and charge a syringe therewith ; thia
