It is unquestionable that tlie animal plagues are propa- 

 gated, in Western Europe and America, only by tlie disease- 

 germs produced in countless myriads in the body of a dis- 

 eased animal and conveyed from that to the healthy. It 

 follows that the destruction of the infected subjects and the 

 thorough disinfection of the carcass, manure, buildings, etc., 

 is the most economical treatment of all the more fatal forms 

 of contagious disease in live stock. For the less fatal forms, 

 the most perfect separation and seclusion, and the thorough 

 disinfection of all with which they have come in contact 

 is still imperative. 



To the first class of exotic maladies belong : 8mall-pox in 

 sheeja and hirds, the lung-blague or contagious pleuro- 

 pneumonia of cattle, the Rinderpest or cattle-plague, the 

 malignant disease of the generative organs in solipeds, and 

 malignant cholera in all animals. These demand separa- 

 tion, destruction, and disinfection. To the second or less 

 fatal class of exotic maladies belongs the Aphthous fever or 

 foot and mouth disease. This demands seclusion and dis- 

 infection. 



Beside these maladies, that are foreign to our soil and 

 which are not to be feared except as the result of importa- 

 tion from abroad and subsequent transmission by contagion, 

 there is a very important class which, though perhaps not 

 generated in America, are widely disseminated over the 

 continent and spread by contagion. Among these may be 

 named : Glanders and farcy, canine madness, contagious 

 foot-rot, tube^^culosis, hacillar anthrax, vihrionic {emphy- 

 sematous) anthrax, Texan-fever, swine-plague, influenza, 

 strangles, canine distemper, and perhaps the variola or pox 

 of horse, cow, goat, pig, and dog. All of these down to 

 swine-plague, like foreign contagious affections, demand 

 separation and disinfection, with destruction or not of the 

 diseased, according to the severity and diffnsibility of the 

 particular malady. The remaindei-, from influenza onward
