QUITTOR. 555 



ing, brought about by the introduction of some caustic 

 substance, after this fashion. When the opening is very 

 small, and the sinuses deep, but contracted, make a paste 

 with equal parts of resin and corrosive subHmate, softened 

 and held together with tar. Impregnate small pieces of 

 wool or tow fully with this paste, which place around the 

 end of a probe, and introduce one by one to the bottom of 

 each sinus, filling also each up to the orifice with the same, 

 but not jamming them in with force. When, on the con- 

 trary, the orifice of the wound is sufficiently large, and one 

 or two straight sinuses only exist, a bougie may be made 

 with paper, dipped in the paste, and introduced ; or in case 

 the diseased action be extreme, and the quittor is very foul, 

 the powder may be rolled within thin paper, so as to make 

 also a bougie, which being greased or rubbed with tar to 

 render it slippery, should be introduced to the bottom of 

 the sinuses ; but it must be remembered, that, when these 

 are numerous and irregular in their direction, the first is by 

 far the best mode. The hoof should, as soon as the caustic 

 is introduced, be put into a poultice. In two or three days 

 after the introduction of the caustic, there will follow great 

 heat and tumefaction of the foot ; and, at last, the orifice 

 will burst out, expelling the slough, together with the 

 application that occasioned it ; after which it may be ex- 

 pected that the wound will go on healthily to heal. If, how- 

 ever, unfortunately, this should not be the case, recourse must 

 be again had to another introduction of escharotics, and in 

 every case remove so much of the horny sole as may be 

 beneath the pipes. The foregoing is severe treatment, 

 necessitated by long standing cases. However, when the 

 quittor is recent, and the sinuses are superficial, have the horn 

 thinned over the seat of the disease, but not to that extent 

 which lets forth blood. Then have the horse cast. Next take 

 a small director and insert it into a sinus. A sharp knife may 

 then be slid along the director, and a cut made outward, slit- 

 ting the sinus open. This is to be repeated as often as shall 

 be necessary. Some tow saturated with solution of blue vitriol 

 is then introduced into each sinus, and the horse allowed to 

 rise, when he frequently gets up sound. The wounds are to 

 be treated in the ordinary manner. Even when the severe 

 treatment is imperative, it simplifies the case if all super-
