Title: Stethoscope for use on a horse

Abstract: This invention is a stethoscope for use by a veterinary surgeon with a microphone transducer (15) mounted within a casing arranged to be held by a harness against the skin of the animal, with the transducer opening coupled to the skin through an enclosed column of air, and the harness held in position by a grid (33, 34) capable of being attached to the animal's hair. The output from the transducer can be transmitted from the animal by radio.
