Description: The lever is 15 cm (6 in) long; It can move in
either a horizontal or vertical orientation (as kymographs can
stand in either direction). This lever is balanced, to permit
easy movement, through a thread that goes over a pulley. All
parts are adjustable. (Expanded caption Copyright 1998, Edward J.
