but should not be carried to the distance which some practitioners rec-

the foul and irritating discharge, being confined, does more injury than 
the delay can possibly produce good. 
In the plan of treatment here proposed, the chief reliance is placed 
on the action of chloride of zinc. It is the peculiar property of that 
agent to suppress fungoid granulations. The author has some experi- 
ence in the use of this salt. Whenever he gave it to a groom to apply, 
and subsequently he found the wound clogged with proud flesh, the man 
was accused of having neglected to employ the lotion. The evidence on 
which the charge was made never, in a single instance, proved erroneous. 
To suppress fungoid granulation is to cure canker. 
The application here advised is, moreover, cleanly. It is the most 
powerful disinfectant. It does not discolor, like the messes now in gen- 
eral use. It is more gentle in its action than undiluted sulphuric acid, 
ete. etc. It will cause none of those terrible fits of agony, during which 
all applications have to be removed, while the foot has to be bathed and 
poulticed. Notwithstanding all authors agree that the absence of water 
and the presence of pressure are indispensable to the cure of canker, the 
frequent dressings will not endanger the life, nor leave the foot in that 
condition which entails a deformed hoof upon the horse for the remainder 
of its existence.
