On Jan. 19, 19'44, a 5-year-old Guernsey cow was presented at the Stange Memorial Clinic with no definite history. Examination revealed a badly infected udder with the right front and hind quarters highly necrosed. The necrosed cold area extended half way up the udder on the right side, and the tissue above this was highly inflamed. Crepitant swellings were found extending to the upper right lip of the vulva, forward ventrally to the sternum, and along the right side to about the fifth rib. Crepitant swellings were also present on the left side along the flank and forward to the ninth or tenth rib.
