became cankered. In one case of canker he was compelled t 
apply the actual cautery all over the surface. 
Mr. Field explained, that when he stated that canker was local 
p ^ lie predisposition existed in th 
texture ol the part, and not in the blood. If it appeared occasion 
ally in all four feet, or changed from foot to foot, it is because th. 
texture is the same in all. So far as his practice extended, no mod 
of treatment would succeed without removing the whole of th 
cankered surface. 
Professor Coleman thought it must be more decidedly con 
stitutional than as dependent merely on texture, from the cir 
cumstance of the Arabian being so seldom affected with canke 
or grease, all other circumstances being the same; and therefore 
and especially if connected with grease, the treatment shouk 
be in some measure constitutional as well as local. 
Mr. Held was even inclined to consider grease very much as i 
local complaint. The predisposition to it w r as as great as ever 
but from superior preventive treatment, and that principally of i 
local nature, it was now comparatively seldom seen. 
Mr. J. Turner once treated a horse that had the disease mon 
than two years. When he saw the animal it had no sole, no frog 
no bars. It was one mass of fungus. Afterwards he found thai 
the foot had no sides, no toes; all was hollow and fungus to th( 
very hair. He used no constitutional means—he did not o-i v( 
one grain of medicine, but applied the knife, the caustic, anc 
pressure diligently and in earnest; and the horse did well. 
Mr. Goodwin bore testimony to the benefit of the applicatior 
of caustic. A good granulating surface could not be produced 
without it. 
Mr. Field used the lunar caustic, Mr. Turner the iEgyptia- 
cum, made with crystallized verdigrease; and both urged the ne¬ 
cessity of uniform and considerable pressure. Professor Coleman 
recommended exercise, as going in a mill; and Mr. King would 
even turn out on a dry pasture in dry weather.
