Abstract
TODAY we turn naturally to photography to analyse movements which are too rapid for our eyes to follow. If we tend to take this powerful weapon too much for granted, it must be remembered that there were formidable experimental difficulties facing the investigator before the advent of photography. Marey, while director of the Physiological Station in Paris, devised a most ingenious way of studying the movements of a horse. Pressure chambers fitted to the underside of the horse's hooves were connected by pneumatic tubes to a recording mechanism held by the rider, which registered the time of duration of contact of each hoof with the ground. Marey did much painstaking work along these lines between 1860 and 1880.
