94 ANTISEPTIC TREATMENT OF WOUNDS. 
By a circular amputation, closely above the edge of the hoof, 
the latter was without much difficulty excised. Haemorrhage 
did not take place, as all vessels were thrombosed. The whole 
operating field, including the wound, was rinsed out with a 
sublimate solution, and by means of jute, which was saturated 
with sublimate water, and a few cambric bands, a bandage 
was put on which reached half way up the metatarsus. To pre- 
vent any moisture and dirt from penetrating through the ban- 
dage it was painted over with tar. 
The after treatment consisted of pouring in sublimate water 
behind the bandage daily, and changing the bandage every 
fourteen days. With this treatment the wound healed within 
eight weeks, without any trace of pus or even exudation worth 
mentioning. 
CROWN PRICK. (TREADS.) 
As in nail prick the importance of crown prick depends en- 
tirely upon how deep the injuring body has entered. As to 
the mode of treatment, however, there is no difference at all 
between the various forms of the trouble, as a superficial in- 
jury is apt to cause disease to the deeper lying tissues, on ac- 
count of a slowly encroaching suppuration downwards. By 
all means surgery has to be resorted to, and according to the 
size and circumference of the injury, oceasionally more and 
at other times less horn, etc., has to be removed, so.that some- 
times the operation can be performed, on the horse standing, 
while at other times he has to be laid down, especially in more 
severe injuries. I proceed as follows: 
After the hair and coarse shreds of tissue in the vicinity of 
the injury have been removed, a cleansing with soap and water 
follows, and finally disinfection by free after rinsing with one 
per cent. sublimate water. ‘After that the horn in the neigh- 
borhood of the wound is thinned, occasionally entirely re- 
moved as far as the connection between the horn and flesh wall 
is loosened. All foreign bodies and hair which may have en- 
tered into the wound, as well as all necrotic or dying shreads 
of tissue, are removed. It is also well to trim off all irregu-
