<p>Apparatus is described for determining cutinous points in an animal body, (for example a human body) where two metallic points (30, 40/64, 66) contact with the body. In use the body and metallic points (32, 40/64, 66) complete a circuit including resistors (6, 22), a transistor (10), transformer (14) and loudspeaker (28). When a cutinous point on the body is located the sound through the loudspeaker (28) changes or some other indication is given.</p> |
