On Dec. 13, 1951, a yearling Hereford bull was admitted to the Stange Memorial Clinic for treatment with a history of having been dehorned December 1. On December 12, the owner had noticed the area around the left eye swollen and had summoned a local veterinarian, who referred the case to the clinic.
