Published lecture given by the pioneering photographer Eadweard Muybridge on March 13th 1882 at the Royal Institution in London in front of a sell out audience that included members of the Royal Family, notably the future King Edward VII. He displayed his photographs on screen and described his zoopraxiscope, a device for projecting motion pictures that pre-dated the flexible perforated film strip.
