The Romance of modern scientific and mechanical Achievements

He also built a photo- graphic gun, in which the pictures were taken upon segments of a disc, the gun being pointed from the shoulder at the object as if firing were contemplated, while the motion of the trigger actuated the shutter mechanism. Marey achieved some beautiful scientific results and shed considerable and valuable light upon the subject of motion, which was his especial study. He even founded an institute in Paris, which is still in existence, and in which the class of work he initiated is still pursued. This institute has since become regarded as the home of scientific cinemato- graphy, and the laboratory is famous for the many ingenious appliances which have been contrived to enable special lines of investigation to be carried out. Incidentally it may be mentioned that many of the ideas which have been worked out at this laboratory expressly for scientific purposes have been adopted by the commercial picture producers. The latter were compelled to popularise the subjects in order to make them appeal to the public taste. Under these circumstances the Marey Institute, which is unique, may be considered as the Home of Cinematography in more senses than one. The French inventor described his apparatus as the “ Cinematograph,” as a distinction from the Edison “ kinetoscope ” and its predecessor the “ kinemato- scope,” while the English inventor, Robert Paul, christened his apparatus the “ Animatograph ” for a similar reason. There was every reason why such should be done, because the Anglo-French achieve-
