The New Student's Reference Work/Cinematograph

Cinematograph (sĭn′ḗ-măt′ṓ-grắf). This is an instrument which casts upon a screen a number of successive views which have been taken from a moving object, in so swift an order that the eye does not observe that the picture has been changed. The spectator appears to behold one and the same view, in which the objects are in actual motion. On an average about 100,000 pictures are needed for an exhibition which is to last one hour. The instrument was invented in 1894 by Edison.
