84 ANTISEPTIC TREATMENT OF WOUNDS. 
canal which is widened with the sharp spoon up to its base, 
with a jtite compress, which is saturated in a I per cent. solu- 
tion of sublimate. On the top of this tampon a pledget of jute, 
fastened by means of a covering iron, is placed, and kept 
moist by occasionally pouring sublimate water on it. A 
change of this bandage is necessary every three or four days. 
Under such treatment all fresh nailpricks heal nearly with- 
out an exception within from eight to fourteen days, on ac- 
count of the antisepsis, which prevents suppuration and its 
consequenices. 
The therapy of all nailpricks, in which the pain does not 
become materially alleviated within five or six days after the 
course of treatment as above mentioned, or when fever sets in, 
(especially in nailpricks, which perforate the flexor tendon, 
that is, old nailpricks, where necrosis in the depth of the punc- 
‘ture canal takes place) is a surgical one, and will be discussed 
later. 
THRUSH WITH LAYING OPEN OF THE SOFT PARTS 
ON BOTH HIND HOOFS. 
As a consequence of permanent standing in urine soaked 
peat litter, on both hind hoofs of a horse the frog was so badly 
macerated, and the side lacunae so putrefied, that in the latter 
the hoof cutis vera was laid open. The disease was diagnosed 
as frog canker, and was accordingly treated chiefly with plum- 
bum nitricum. This treatment did not heal the wound, and the 
owner was recommended to have the animal destroyed. 
On my recommendation the horse was treated in such a 
way as to have the wound rinsed with a I per cent. sublimate 
water and bandaged up afterwards with iodoform tannin (5 
per cent.) and jute. In the course of four weeks, healing re- 
sulted, during which time the horse worked along in the 
field. 
SUPPURATING STONE BRUISES. 
As a rule in suppurating stone galls we simultaneously find 
necrosis of the soft parts in larger or smaller dimension and
