That marvelous organ which, moment by moment and year by year, keeps

This series of articles deals with heart therapy, not discussing the
heart structurally and anatomically, but taking up in detail the
various forms of the disturbances which may affect the heart. The
cordial reception given by the readers of The Journal to this series
of articles has warranted its issue in book form so that it may be
slipped into the pocket for review at appropriate times, or kept on
the desk for convenient reference.
