Abstract: To obtain maximum information from rapid serial studies of living subjects, the films should be viewed both in slow motion and as stills. Thii requires special projection apparatus. Alterations carried out on a Kodak “Analyst” projector make possible tolerably flicker-free projection at speeds between 15 and 6 frames/sec and also pushbutton controlled single-frame operation, either forward or reverse. Changedver from continuous to single-frame operation can be made quickly, without manual adjustment of focus or illumination.
