 One of the pictures to be seen in the machine, for example, was that of a blacksmith shop in which two men were working, one shoeing a horse, the other heating iron at the forge. One would be seen to drive the nail into the shoe of the horse s hoof, to change his position and every movement needed in the work was clearly shown as if the object was in real (life). In fact, the whole routine of the two men s labour and their movements for the day was presented to the view of the observer.
