DIAGRAM ILLUSIONS. 39 Fig. 43. possessed by those materials best fitted for printing on, and which is at the best somewhat difficult to maintain in apparatus in constant use. A large number of these Mutoscopes, worked on a coin-freed principle, formed one of the features of the Photographic Exhibition at the Crystal Palace in May, 1898. Messrs. Lumiere's Kinora (Figs. 43 and 44) is very similar in principle, but varies in a few de- tails, mainly directed towards the important matter of resiliency. The pictures are mounted on flexible supports, blackened on the back to obviate reflection of stray light, and these supports possess a curved form. The cylinder is rotated by a clockwork motor, H, so as to bring the concave sides of the pictures towards the inspection lens inserted through the top of the casing. A stop, C, arrests the pictures before they reach the lens, to the axis of which they are held at right angles, the curve in the flexible support straightening out to compensate for the rotary movement of the axle. Each picture therefore lies per- fectly flat for inspection and then flies rapidly past the lens, returning to its proper radial position and curved form by virtue of its elasticity. The apparatus may also be set in motion by hand, and if more than one scene is depicted in the series an automatic stop, J, is provided. A simple form of this type which has recently made its appearance in the shop windows is Fig, 44.
