This monograph is an authoritative discussion of the graphic registration of the heart tones. A review of the efforts of others in this line is followed by an account of the author's own methods. The physical principles involved are fully considered and the various instruments described, with help from diagram and illustration. Then follows a discussion of the graphic representation of the normal heart tones and later the endocardial murmurs, those of mitral regurgitation and mitral stenosis being dwelt on with especial detail. The possible erros in technic and in the interpretation of the tracings are pointed out. A very complete bibliography, and excellent work by the printer and illustrator make the brochure an invaluable one to the student of this'special feature of cardiac physiology and pathology.
