580 MULLER November and go through many modes of motions. Granted that there is a major direction, it is nevertheless important to know about the minor ones. An easy way to perceive these complex motions is to observe them visually and in order to accomplish this we have to resort to motion pictures which can reproduce the action in slow motion. For the study of sound vibrations, the Bell Telephone Laboratories developed a high-speed motion picture camera known as the Fastax which LIGHT-TRAP LEVER GROUND-GLASS SCREEN (8 MM MASK) (OPEN POSITION) VIEW FINDER Fig. 1 — The Fastax camera. seemed to be .ideally fitted to do the job of recording shock displacements. Fig. 1 shows a view of this camera. The Eastman Kodak Company has also developed a high-speed motion picture camera equally well suited for the purpose and is shown in Fig. 2. In Fig. 3 we have a simple schematic showing the use of a prism to obtain an image on the film ; in other words, both cameras belong to the rotating-prism type. Either 8 or 16-mm film can be used. The average maximum exposure is 4000 frames per second for 16-mm and 8000 frames per second for 8 mm. For shock work, we rarely, if ever, use the 8-mm. We have found that 16-mm at 4000 frames is quite satisfactory.
