Two intrepid pioneers of science announced a stomach-shaking discovery last week. Drs. Alfred H. Free and Jack R. Leonards, both biochemists at the medical school of Cleveland's Western Reserve University, first stuffed themselves on horse meat. (They would have preferred beef but lacked the ration points.) Then for several days they fasted, testing their blood at intervals.
Next each drank about three quarts of beef blood. Again for days they fasted and tested.
