Reference has already been made to the peripneumonia which cuts off horses, tolos or koodoos.

Great numbers also of zebras are found dead with masses of foam at the nostrils, exactly as occurs in the common "horse-sickness".

The production of the malignant carbuncle called kuatsi, or selonda, by the flesh when eaten, is another proof of the disease of the tame and wild being identical.
I once found a buffalo blind from ophthalmia standing by the fountain Otse; when he attempted to run he lifted up his feet in the manner peculiar to blind animals.

The rhinoceros has often worms on the conjunction of his eyes; but these are not the cause of the dimness of vision which will make him charge past a man who has wounded him, if he stands perfectly still, in the belief that his enemy is a tree.
It probably arises from the horn being in the line of vision, for the variety named kuabaoba, which has a straight horn directed downward away from that line, possesses acute eyesight, and is much more wary.
All the wild animals are subject to intestinal worms besides.

I have observed bunches of a tape-like thread and short worms of enlarged sizes in the rhinoceros.
