ANTHRAX. Distribution--(i) Geographically, Anthrax is met with all over the world, being most common in Siberia, rare in England, and comparatively rare in America; and (it) Zoologically, there are a very large number of susceptible animals. Cattle and sheep suffer worst of;all, but horses, guineapigs, rabbits, and mice are also prone: and especially the young of all susceptible animals. Dogs, cats, amphibians, and most birds are practically immune; while white rats are infected only with difficulty. Discovery of the disease.--Davaine in 1863, by inoculating the blood of anthrax-infected sheep into other sheep, and reproducing the disease typically in the latter, satisfied Koch's first canon; and Koch himself many years afterwards managed to isolate the bacillus. Both he and Pasteur grew 't in pure cultivation, and then by injecting it into suitable susceptible animals from whom the bacilli were afterwards obtained, succeeded in satisfying the remaining two canons. A rod-shaped, rectangular, non-motile Morpnology. bacillus, without flagella, occurring when in the blood of the living infected animal as short single or jointed segments, 6--9 or more long, and about lp broad, with cup-shaped ends--and never, under such conditions, containing spores.
