Mr. J. Turner hazarded an opinion at variance with the pro- 
ssion. He thought canker a mere local disease : as completely 
» as any other. In all his cases he had been tolerably successful ; 
id he had carefully abstained from any constitutional treat- 
ent. He applied caustic, so completely as to destroy every part 
‘ the fungus; and persevered until the wound had a perfectly 
ialthy granulating surface. Exercise, spare diet, and pressure 
lould be diligently attended to. 
Mr. Field thought that Mr. Turner’s theory would have taken 
; e profession by surprise; whereas it was that to which he, and 
■ i believed almost every practitioner, subscribed. He never re- 
irded it as a constitutional disease, nor knew of any one who 
d. This was one of those circumstances w r hich showed the 
icessity of the Veterinary Medical Society , that we might really 
low what each believed and practised. 
Professor Coleman understood Mr. King to say, that the pro- 
my of the cankered stallion was cankered. This must be con- 
itutional. Horses with thick skins are more disposed to grease 
id canker—thus far constitutional. Not the disease, but the 
•edisposition to it, from their peculiar conformation, inherited from 
e sire. A person with a narrow chest is liable to consump- 
in. He does not inherit consumption, but he inherits that 
articular form which disposes him to consumption. 
Mr. King. —If you cure one foot the other will often become 
fected—nay, it will sometimes go all round : this looks as if it 
ere constitutional. 
Professor Coleman. —It is possible that both parties may be, 
■ a certain degree, right, and both wrong. If a horse were af- 
cted with grease that ended in canker, you would deem it right 
■ give diuretics, in order to cure the grease; and the removal of 
le grease would facilitate the cure of the canker. In the 111 a- 
•rity of cases there is grease, and grease previous to canker. 
Mr. Goodiuin firmly believed it to be constitutional. It was 
mnected with grease—it alternated with grease,—and it changed 
‘om foot to foot. 
I Mr. J. Turner asked how it w r as to be accounted for, thatquittor 
lould so often degenerate into canker,—this could not be con- 
ltutional. 
Mr. Mavor. —There was a predisposition in the foot to take 
I canker. He lately had under his care a bad case of canker. 
II the sole was destroyed, and the greater part of the hoof, 
aving only about two inches of sound horn at the coronet,
