Mine Detector Diagnoses Cows (Sep, 1950)

Mine Detector Diagnoses Cows
The man in the white coat above doesn’t think that Bossy has a Tellermine in her cud, but he is checking to see if she’s munched a nail, screw, or bit of barbed wire. Because cows sometimes eat metal objects that cause sickness, British vets use mine detectors along with their stethoscopes. Other uses for surplus detectors are to locate metal embedded in logs that might shatter saw blades, and to spot the hairpins that women workers tend to shed into food-package assembly lines.
