In an endeavour to present the outline of the development of cardiology in Australia as a continuing process, gradually gaining its own individual characteristics, attention was arrested by certain outstanding individuals and important milestones. Rather than attempt to cover the entire subject, an undertaking too ambitious for the present study, four chapters are offered to illustrate the progress of the speciality on this continent. If they serve to stimulate interest in Australian cardiology their purpose will have been fulfilled and the writer amply rewarded.
