46 LIVING PICTURES. Fig. 47. Paris, it would be of great interest to ascertain the methods proposed. It is well to devote some attention to the years 1869 and 1870; that is to say, the period immediately preceding- the first attempts in chrono- photography. Two forms of apparatus, casually quoted on page 21, give a very clear idea of the stage of progress then attained; and they are the more inter- esting inasmuch as the instrument in- tended for use with drawn designs shows a greater approximation to modern machines than does the one which employed photographs. Brown's apparatus, shown in Figs. 47 and 48, depended on non-photographic images, of which a series was painted on a polygonal glass plate, P, and dropped into a holder somewhat similar to a magic-lantern slide. A gear - wheel, shown in Fig. 48, served to rotate the designs, and was itself revolved intermittently by pins contained in the lantern, with which it engaged when the slide was pushed home. These two pins projected from a disc and engaged periodically with a star-wheel, fromed in one piece with the gear-wheel Fig. 48.
