Others in this country have disputed the contagious character of the disease, and considered that the same conditions of the pasture which pEoduced the disease in a flock would produce it again in imported animals, which would account for the apparent contagiousness. Brown, in order to test the question of contagion, placed infected sheep in a pen, the bottom of which was covered with straw which was not removed while the experiments were in process. Three healthy sheep, from a locality where foot-rot was unknown, were placed \vith the infected sheep. At the end of ten days the feet of the sound sheep were still healthy.
