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.

Like most other patient files of the fonds, almost all of these files contain heart sounds diagrams drawn by Dr. Segall, 6x12" clinical history forms, sections of electrocardiograms attached to dated cards, as well as 4x6" normal heart sounds record forms completed by Dr. Segall which are often accompanied by sections of electrocardiogram readings. Many files also contain correspondence between Dr. Segall and other doctors, medical institutions, and health insurance companies, and occasionally correspondence between Dr. Segall and the patient and/or the patient's family.
