cle with others thnt can in no wise increase the certainty or speed of its 
operation. It is the empiric only, that, ignorant of diseases and their 
true remedies and firing at random, puts a handful of shot into his gun 
with the hope that some one of them will hit the marie. 
The best time to extirpa'e this disease from a flock is the fore part of 
the season. When the sheep are got up to be tagged, their feet should 
be carefully examined. Every one that exhibits the slightest ulceration 
at the root of the hoof, giving olf that offensive fetor peculiar to the foot- 
rot, should then be separated from the rest of the flock. A person ac¬ 
quainted with this disease can tell with certainty every sheep that is af¬ 
fected by it. As this examination is making, spirits of turpentine should 
be poured into the clefts of the feet of all the sheep ascertained to be 
sound, in order to wash out and destroy any particles of the virus that 
may be lodged there. This will secure the unaffected members of the 
flock from having the disease break out among them. The diseased 
sheep must henceforth be kept by themselves, until the whole are cured. 
To effect this cure the hoof must be cut away so as to freely expose all 
of the diseased part. This is an indispensable part of the treatment. 
It can commonly be performed without putting the sheep to any severe 
suffering. But sometimes the affected parts are sore and tender, and if 
the point of the knife accidentally touches the quick, the sheep may get 
to struggling so violently that it will be necessary to tie its feet to com¬ 
plete the work in hand. Apparent cruelty here, is mercy to the animal 
in the er.d. The foot, moreover, in some cases gets to bleeding so pro¬ 
fusely that it is impossible to see whether the whole of the hoof over the 
sore is removed; the timid operator often hopes he has exposed the 
whole of the diseased part, and desists when his object is but partially 
accomplished ; and he hereby is under the necessity of renewing it at a 
subsequent day. 
The hoof being pared away so as to expose the whole extent of the 
ulcer, blue vitrol alone or in combination with other substances is to be 
applied to its surface. G. Campbell informs me that the dry powder, 
formed by pulverising this salt, freely dusted over the sore, is all that is 
necessary, and is as efficacious as any application can be; the sore be¬ 
ing hereby entirely healed over in a majority of cases, within about five 
days, and a perfect cure accomplished. Others, in addition to dusting 
with vitriol powder, pour spirits of turpentine upon the sore, but I doubt 
whether this contributes anything towards the cure. It will, it is true, 
repel the flies from depositing their eggs here; but if the vitriol ulone 
excites a healthy action, causing the sore to heal so speedily, there can 
be little danger of the exposed part becoming the nidus of maggots in 
the interim. If it is preferred to have this medicine in the form of a
