under this treatment, but gradually becomes smaller, and in about three 
weeks the cavity, which was as large as a child’s head, will have 
completely filled up. 
An abscess of the shoulder, extirpated on July 16th, left behind a^ cavity 
7 inches long, 4 inches broad, and 2f inches deep. Until the 22nd no 
marked change had occurred, but subsequently the dimensions were reduced 
as follows :—

In such cases open wound treatment is not only the quickest, but the 
most convenient. When a dry scab is produced over the entire wound 
nothing further is necessary. The margins of the wound being laid back t 
obviously prevents their being drawn inwards by cicatricial contraction, 
which is apt to interfere with healing. 
YI.—SADDLE AND COLLAR GALLS—INJURIES FROM 
PRESSURE. 
The saddle and collar exercise heavy pressure on the tissues below, 
and may produce injuries to the skin or subjacent textures. These are 
usually of the nature of bruises, seldom of excoriations; and as those 
produced by the saddle possess the greatest interest, they will be first 
considered. 
(1.) INJURIES PRODUCED BY THE SADDLE- 
SADDLE-GALL S. 
To prevent the pressure of the saddle injuring the back, the following- 
precautions must be observed :— 
(1) Pressure should be distributed as evenly, and over as large a 
surface, as possible. 
(2) Pressure must be confined to parts fitted to bear it. 
(8) Those portions of the saddle which bear on the body must be 
properly stuffed, or the back covered with a folded rug, Ac. Weight can 
only be borne where muscles or fat underlie the skin, as is the case along 
both sides of the vertebral column in the dorsal region. 
In the middle line of the back and on the withers, where the bones are 
not cushioned, any considerable pressure causes bruising, baddies are, 
therefore, made to bear on* the protected parts only.
