Metchnikoff and Th. Smith working independently found a fair 

 measure of success in inoculating rabbits and guinea pigs with 

 three to five small injections of sterilized bouillon cultures, agar 

 cultures of blood, intravenously, intra-abdominally or hypodermi- 

 cally. But as applied to swine it has not proved satisfactory, and 

 the irregularity of the results and the tendency to induce un- 

 thriftiness have caused it to be abandoned. 



Treatment. The therapeutics of swine plague like that of hog 

 cholera is essentially unsatisfactory. Benefit might be derived in 

 individual cases from a careful and judicious use of drugs to 

 meet the special indications, but with the comparatively low 

 value of the individual animal, the certainty of the multiplica- 

 tion of the deadly poison by the preservation of the diseased,, 

 ard the extreme danger of its diffusion and extension, treatment 

 is anything but commendable. 



Serum-therapy has been advocated for years by De Schweinitz/ 

 and under the auspices of the bureau of Animal Industry it has 

 been given a wide trial, but it has not met with the full success, 

 that was at first claimed for it. The serum is prepared in a simi- 

 lar way to that of hog cholera and is similarly employed. It is 

 open to the same class of objections, and though when skillfully 

 employed it will reduce the mortality, it does not yet seem to 

 have reached the point at which it can be recommended as a 

 profitable investment. I/ike all temporizing measures it draws 

 attention from the sounder and more economical measure of ex- 

 tinction and is indirectly a means of the perpetuation and even 

 the diffusion of the infection. So long as extinction cannot be 

 secured, this is a less valuable alternative for the adoption of 

 owners of high priced hogs. 



MODIFIED AND COMPIyKX FEVERS OF SWINE. 



Double infections. Varieties of bacillus choleras suis, and bacillus suis- 

 pestis. McFadyean's swine fever bacillus. Marseilles swine plague bacillus. 



We accept fully the duality of the Hog Cholera and Swine 

 Plague, though this duality has been hotly contested on both 

 sides of the Atlantic. Many of the best observers in Europe 

 now support this position. These include Selander, Bang and
