Contagious and Epizootic Diseases. 



sion, and tlae thorougli disinfection of all with which they 

 have come in contact is still imperative. 



To the first class of exotic maladies beloug : Small-pox, 

 in sheep and bizds ; the lung-fever or contagious pleuro-pneu- 

 monia of cattle; the Rinderpest or cattle-plague ; the ma- 

 lignant disease of the generative organs in solipeds ; and ma,- 

 lignant clwlera in all animals. These demand separation, 

 destruction and disinfection. To the second or less fatal 

 class of exotic maladies belongs : the Aphthous fever ox foot 

 and mouth disease. This demands seclusion and disinfec- 

 tion. 



Beside these maladies, that are foreign to our soil and 

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

 tation from abroad and subsequent transmission by conta- 

 gion, there is a very important class which are apparently 

 generated in America and thereafter spread by contagion. 

 Among these may be named : Glanders and farq/, canine 

 madness, contagiousfoot-rot, tuhercidosis, malignant anthrax, 

 Texan-fever, intestinal fever of siuine or hog-cholera, influ- 

 enza, strangles, canine distemper, and perhaps the variola or 

 pox of horse, coiv, goat, pig, and dog. AU of these down to 

 intestinal fever of swine, like foreign contagious affections, 

 demand separation, and disinfection, with destruction or not 

 of the diseased, according to the severity and diffusibility 

 of the particular malady. The remainder, from influenza 

 onward, are either too mild to warrant such measures, or 

 too easily spread to be satisfactorily controlled by them. 

 It is beyond the purpose of this work to enter into the 

 special legislative enactments necessary to prevent the 

 importation of foreign plagues, or the spread of nati^& 

 or imported ones. For this the reader is referred to the 

 author's larger work. A few words on disinfection are, 

 however, indispensable. 



DISINEECTION. 



The first and main object in disinfection is to secure 

 perfect cleanliness. From the buildings, cars, loadmg-
