PLEURO-PNEUMONIA. 251 that disease to healthy animals coming in contact with diseases, therefore, travel very slowly, starting,as they do, at one point, and-gradually spreading over a largedistrict, or section of country. This disease is, however, regarded by the author as infec-tious ; by which term is meant that it is capable of beingcommunicated from the diseased to the healthy animalthrough the medium of the air, which has become contami-nated by the exhalations of poisonous matter. The abilityto inoculate other animals in this way is necessarily confinedto a limited space, sometimes not extending moie than a fewyards. Infectious diseases, accordingly, spread with morerapidity than contagious ones, and are, consequently, moreto be dreaded; since we can avoid the one with compara-tively little trouble, while the other often steals upon uswhen we regard ourselves as beyond its influence, carryingdeath and destruct
