On the evening of April 18, 1947 an albino 3 year old mare was entered at the Stange Memorial Clinic with the history that the right hock had been cut on a fence the morning of April 17, 1947. The veterinarians who first attended the animal had applied a pressure bandage infiltrated with powdered sulfanilamide to control hemorrhage and administered tetanus antitoxin.
