THE INVENTION OF THE STETHOSCOPE.

FIRST EDITION, FIRST STATE, with sig. A*2 uncancelled and with all original typographical errors. Laennec's groundbreaking treatise on the invention of the stethoscope and its medical applications. Laennec would later recall, "In 1816, I was consulted by a young woman laboring under general symptoms of diseased heart, and in whose case percussion and the application of the hand were of little avail.... The other method just mentioned direct auscultation being rendered inadmissible by the age and sex of the patient, I happened to recollect a simple and well-known fact in acoustics... the great distinctness with which we hear the scratch of a pin at one end of a piece of wood on applying our ear to the other. Immediately, on this suggestion, I rolled a quire of paper into a kind of cylinder and applied one end of it to the region of the heart and the other to my ear..." For nearly thirty years the cylindrical design of the stethoscope was standard; the modern type with two earpieces was invented by Arthur Leared in 1851.
