FUNGUS HÆMATOIDES, OR CANCEROUS GROWTHS WITHIN THE SUBSTANCE OF THE EYE. ] At last the eyes are examined. The eyeball may be clear, but some brilliant yellow substance may be discerned shooting from the base of the interior, and the horse is declared contaminated by a cancerous disease. All is now explained: the sight is lost; the horse is blind. There are three terrible decisions now left to the master. Is the life to be shortened? The thought shudders at taking existence, when misery pleads for consolation. Is the animal to live on and nurture to maturity the seeds of a cancerous disease? The mind shrinks from subjecting any creature to the terrible depression and hopeless agony attendant upon such disorders. Is an operation to be performed? Shall the surgeon extirpate the eye? This last proposal seems the worst of all; nor does inquiry improve the prospect. The cancer does not entirely reside within the eye; it is not limited to that part. The taint is in the constitution, and the operation can do no more than retard its effect. The eye removed, the cancerous growth will soon fill the vacant orbit. After two or several months of dreadful suspense, the life at last will be exacted, and the animal, worn out with suffering, will expire. Under such circumstances, the writer recommends death, before the full violence of the disease is endured. Should, however, the reader think differently, and prefer the extirpation of the eyeball, the operation will here be described. First, mind the operator has two knives not generally kept by veterinary surgeons: one of small size and slightly bent to one side; the other larger, and curved to one side till it has nearly reached a semicircle. Mind the operator has everything ready before he begin: a sharp scalpel, two straight triangular-pointed needles, each armed with strong twine; one curved needle, similarly provided; sponge, water, injecting tube, bellows, lint,--and all things at hand. It is necessary the proprietor should see to this, as some men will commence an operation upon a mere horse and be obliged to stop in the middle, not having brought all the instruments which they may require.
