The pathogenetic differences between the viruses of cowpox and vaccinia, found by means of Pauls corneal test, are discussed. The variation in the morbid course in cattle after infection with cowpox or vaccinia is described. Cowpox in cattle has an incubation stage of 3-8 days and cutaneous efflorescence requires 7-12 days to mature, whereas cattle inoculated with vaccinia virus show cutaneous manifestations after 2 days and fully mature efflorescences after 5-6 days.
