On August 3, 1954, a 6-year-old female Collie was admitted to the Stange Memorial Clinic with a history of having an upset stomach for the past several days. Penicillin had been administered, but no improvement was noticed. The animal was examined and found to be extremely depressed and in a toxic condition. The conjunctiva appeared injected and the temperature was 103°F. A hard mass could be detected upon palpation of the lower abdomen on the left side.
