138 VETERINARY SURGICAL THERAPEUTICS. 
a severe inflammation of the eye; the entire exposed surface of the 
ocular globe was filled with little wounds looking as if they had been 
made with a punch. Subcutaneous lesions produced by dead projec- 
tiles, which push into the skin without running through—lesions attrib- 
uted in days gone to the “ wind of the ball or the bullet,”—-must be treated 
as contusions. If the skin and the superficial subcutaneous layers be- 
come necrosed, the sloughing of the mortified tissues should be at- 
tended to. (See Gangrene.) The examination of a contused wound of 
the hoof bya ball (Kopp) disclosed the fact that the deep layers of the 
hoof were infiltrated with blood, as in a corn, and that under the wall 
there was a small hemorrhagic center. 
A load of shot, if fired at short range, has the effect of a bullet, and 
gives rise to all the disorders of the most contused wounds; if the 
shooting is made at long range, the shot penetrates the tissues sepa- 
rately, and makes in them narrow and more or less deep tracts, at the 
bottom of which it is enclosed in a cyst. Only the shot that is super- 
ficially situated, which is troublesome, or is arrested in delicate tissues, 
such as the eyelids or the cornea, is removed at once (Peuch). 
Wounds in the shape of gutters, hollowed in the skin and superficial 
subcutaneous layers by a ball which has reached them at right angles, 
cicatrize by granulations and without severe inflammatory reaction. 
It is sufficient to make simple washings and to cover them with an an- 
tiseptic preparation. Immediate reunion might be obtained in some 
cases if the contused condition of the borders did not prohibit. 
Tubular subcutaneous wounds, like a seton tract, produced by balls 
of all sizes, which pass through and through a region, generally close 
quite rapidly and without suppuration, except at their openings. They 
must not be probed or enlarged unless they conceal some foreign 
body; in other cases, they are aseptic, just as the tract of a trocar 
heated to white heat, and the probing exposes them to infection or 
destroys adhesions already made and interferes with cicatrization. 
Clip the hair around the openings, wash these with a strong solution 
of carbolic acid or corrosive sublimate mixtures, cover them with iodo- 
form or iodoformed vaseline, and immobilize the region. These are 
the only truly useful measures to take. If a fluctuating center appears 
in the subcutaneous tract, it should be punctured, the cavity washed, 
all foreign bodies that it may contain removed, and then it should be 
dressed as the openings were. When the tracts of the wounds running 
in the depth of a region pass through an aponeurosis, if the tissues 
underneath become highly inflamed and suppurate, it is necessary to 
enlarge the tract and drain it. The hemorrhage which takes place in 
some cases is also a condition which demands free incisions, but the 
march and the gravity of the trouble depend, after all, upon the impor- 
tance of the injured organs. It is evident that balls, which thus
