with the history of cardiac surgery, there may be difficulty in finding the reference to a particular point. Usually, however, the major points are indexed and it is only ones ancillary to cardiac surgery that one must search for. The margins are liberally sprinkled with line drawings of many of the pioneers. The sketches add charm to the presentation, even though they are not always good likenesses. This is a volume for the medical school library and for the cardiac surgeon. It will provide pleasant reading for students of medical history for a long time to come.
