Series contains case histories of Trans Canada Airlines and Ferry Command pilots. As Dr. Segall explains in "The evolution of the record system" (Box 308), the TCA and ferry command patient records were segregated in order to provide a collection of normal patterns of heart sounds from which he could develop a model pattern for heart sounds. This normal model pattern was then used as the standard against which he could compare the heart sounds of other patients.
