The preventive treatment consists in keeping the quarters and yards in a sanitary condition, and using all possible precau- tions against the introduction of the disease into the herd. The diseased young and mother should be separated fi-om the herd and the quarters disinfected daily. The mouths of all the young should be ex- amined daily and the diseased animals treated. The ulcers should be scraped or curetted and cauterized with lunar I caustic, and the mouth washed daily with a two per cent water solution of a cresol disinfectant.

It is usually most economical to kill the badly diseased animals, as they usually die or become badly stunted. Rabies, Hydrophobia.—Rabies is an infectious disease af- fecting the nervous system, that is transmitted by the bite of a rabid animal and the inoculation of the wound with the virus present in the saliva. It is commonly considered a disease of dogs, but because of the disposition of rabid dogs to bite other animals, rabies is common in domestic animals and man. Eabies is widely distributed, being most prevalent in the temperate zone, and where the population is most dense. It has been excluded from Australia, Tasmania and New Zealand by a rigid inspection and quarantine of all imported dogs. The specific cause of rabies is probably a protozoan para- site (the Negri bodies present in nerve-cells, Fig. 105). The. Please note that
