CHRONO-FHOTOaRAPHY. 49 investigating animal motion, laid out a course, similar to a running-path, one side being bounded by a white background so as to obtain silhouette figures. Along the other side was ranged a series of cameras, the shutters of which were released by electro-magnets, set in action by the moving object itself by means of strings placed across the path, as seen in Fig. 50. This device allowed large pictures to be taken, every one repre- senting the object as it appeared in front of the lens by which the photograph was secured; but it was absolutely necessary not only that the members of the object should be in motion, but also that the object itself should move along the path. Still, this method was adopted by Anschiitz 01 Lissa, in Prussia, with magnificent results, and series of photo- FiG. 50. graphs so obtained by him met with a ready sale when printed on bands appropriately slotted for use as a Tachyscope (see page 25). Much of his success was due to the employment of an improved form of shutter, very similar to the present focal-plane pattern with adjustable opening. Not only were his photographs prepared in this manner for inspection, but in the year 1889 he brought out his so-called Electrical Tachyscope^ though there was no point of similarity between this instrumicnt and the Tachyscope proper. As will be seen by the illustration (Fig. 51), transparent photo- graphs were arranged in series round the margin of a disc contained in an inner room and revolved before an opening equal in area to one design. Both the inner E
