234 INJURIES. 



little with the point of a probe, and worked about the sinuses, 

 until the paste appears at the orifice above. After this is 

 done, the horse is walked for an hour or two — or even sent 

 to slow work again — which produces a still more effectual 

 solution of the caustic, tending also to its uniform diffusion 

 into every recess. The consequence of this caustic dressing 

 is a general slough : every part of the diseased surface is 

 destroyed, and the dead particles are discharged as a curdled 

 mass, called the core. This mode of treatment is often 

 effectual ; for granulations follow the slough, and fill up the 

 sinus. This is to be the treatment, provided the disease has 

 not yet invaded the cartilages. In quittor originating in a 

 '^festered corn^^ which has broken out between hair and 

 hoof, it is a practice that often succeeds, to pass a seton through 

 it and retain it in for a few days. The parts will then take 

 on healthy action, and will heal up. I can, however, recom- 

 mend another mode of treatment on account of its mild 

 operation. I am alluding to — 



Mr. Newport's Method of Cure. — "After the shoe has been re- 

 moved, thin the sole until it will yield to the pressure of the thumb ; then 

 cut the under parts of the wall in an oblique direction from the heel to the 

 anterior part, immediately under the seat of complaint, and only as far as 

 it extends, and rasp the side of the wall thin enough to give way to the 

 pressure of the over-distended parts ; and put on a bar-shoe, rather 

 elevated from the frog. Ascertain with a probe the direction of the 

 sinuses, and introduce into them a saturated solution of sulphate of zinc, 

 with a small syringe. Place over this dressing the common cataplasm, 

 and renew the application every twenty-four hours. I have frequently 

 found three or four such applications complete a cure. I should re- 

 commend that when the probe is introduced to ascertain the progress of 

 cure, it be gently and carefully used ; otherwise it may break down the 

 new-formed lymph. I have found the solution very valuable where the 

 synovial fluid has escaped ; but not to be used if the inflammation of the 

 parts be great." This information is evidently the result of practice, and 

 comes to us in too straightforward a form to be either doubted or 

 disputed. 



Other Modes of Core are to be resorted to when these fail; and 

 cases do present themselves in which we are compelled to adopt measures 

 of a nature which nothing short of absolute necessity could warrant. 

 When the substance of the cartilage has become carious, very question-
