450 POSITION OF PROJECTION APPARATUS [Cn. XII The lantern should be fastened to a hinged board when it is elevated considerably (fig. 118, 242). § 615. Magic lantern on the lecture table. — Occasionally it is an advantage to have the magic lantern on the lecture table ; then the lecturer can manipulate it himself. There are three arrangements possible: (i) The lantern is pointed toward a screen at the side of the room (fig. 243). (2) It is pointed obliquely upward toward the screen in front of the audience. In this case the screen must be inclined toward the lantern as indicated above (§614). (3) Occasionally, for ease of manipulation, the lantern is pointed obliquely upward toward the audience and a plane mirror reflects the image-forming rays backward to the screen (fig. 244). If a mirror is used, the lantern slides must be inserted with their faces toward the objective. FIG. 242. MAGIC LANTERN TABLE WITH HINGED BASEBOARD. Hinges connect the baseboard to the table at the left. By putting a block under the board at the right, it can be elevated to bring the screen picture higher up (fig. 118).
