 bursts, producing a very troublesome disease, and requiring both 

 patience and perseverance to effect a cure. 



Symptoms. It is recognized by the small aperture at the 

 coronet, which seems almost overgrown with " proud flesh." The 

 discharge is glary and constant. On examining* it with a probe, 

 sinuses are found running in all directions. The quarter is en- 

 larged and bulging, and the lameness severe and protracted. 



As I cannot do better than give the treatment used by Mr. 



Gamgee,* which is recognized 

 as the very best, I will give it 

 in full : 



" After taking off tho shoe, 

 and doing all that is necessary 

 to the hoof, I prepare to inject a 

 mixture, for the pharmaceutical 

 combination of which I say noth-

 To prepare the mixture, take 

 bichloride of mercury, one

I inject the mixture down the sinus. This requires to be carefully 

 but very effectually done. The direction of the syringe must there-

 and backward direction, the object being to infiltrate the mass as far 

 as it can be penetrated by the innumerable small sinuses converging 

 to the outer channel. To do this part well, one strong man is better 

 than several hands, if the horse's head be held steady, and an assist- 

 ant hand the instruments, etc. I take the horse's foot forward upon 

 my knee, and, as a rule, succeed in performing the operation with-

 requiring a little exceptional care, may occasionally occur when 

 previous treatment and torture have been resorted to. Uow for
