358 DISEASES OF THE HORSE’S FOOT 
that the whole of the preliminary antisepticising of the foot 
that we have described, and the after maintaining of asepsis 
that we are now about to relate, must be methodically and 
thoroughly carried out. It is of even more importance than 
little details in the operation itself. 
In the first and second methods of operating, directly the 
actual operation is over, the surface of the wound and both 
surfaces of the skin-flaps should first be thoroughly douched 
with a 1 in 1,000 solution of perchloride of mercury. Bayer 
prefers a 1 in 5 solution of iodoform in ether. 
Next, either iodoform or chinosol in the powder should be 
dusted over the whole surface, including again both inner 
and outer faces of the reverted skin-flaps. This done the 
flaps are allowed to fall into position and sutured there 
with carbolized silk or gut. 
Another liberal application of an antiseptic dressing 
follows this. Iodoform, iodoform and boracic acid, or 
chinosol, is freely dusted over the wound and for some 
distance around it. Bayer, however, again prefers a dress- 
ing of the wound, and especially the moistening of the line 
of sutures with the 1 in 5 solution of iodoform in ether. 
Over the wound is then placed a protective layer of 
gauze, impregnated either with boric acid, with a mercuric 
salt, or with iodoform. 
Finally, numerous small and lightly-rolled balls of dry 
carbolized tow are packed regularly over the whole of the 
operation wound, and the foot bandaged. 
Practical points to be remembered in this after-dressing 
are: (1) The balls* of tow should be numerous enough to 
exercise pressure upon the sutured flap when the foot is 
finally bandaged. (2) The bandage should be run on from 
the coronet downwards, in order to insure pressure being 
exerted in the exact position over the sutured flap. 
(3) Bandages should be used in abundance, commencing 
* Bayer recommends that the tow be rolled into cylindrical tampons, 
each long enough to cross the wound. These are placed on the wound 
in alternate horizontal and vertical layers, so that when rolled round 
by « bandage they are pressed into an even and compact pad.
