Chapter XXII.

1. Dogs suffer from these diseases which have received these names, lytta, cynanche, podagra. The lytta produces madness, and they infect every creature which they bite, except mankind, with the same disease. This disease is fatal to dogs and to any other animal they may bite except man. The cynanche also is fatal to dogs; and there are comparatively few which recover from the podagra. Camels also are seized with lytta. (The elephant does not appear to suffer from any other infirmity except flatulency.)

2. Gregarious oxen suffer from two diseases, one called podagra, the other craurus. The podagra affects their feet; but it is not fatal, nor do they lose their hoofs. They derive benefit from their horns being smeared with warm pitch. When attacked with craurus, their breathing becomes warm and thick. Fever in mankind is the same as craurus in cattle. It is a sign of this disease, when they hang down their ears and will not eat. It soon proves fatal, and when dissected, their lungs appear putrid.
