Another reason for the fact that this stethoscope is not sufficiently appreciated in this country is that many of the instruments sold are defectively made. Unless proper attention has been paid to all the nice points of the stethoscope as devised by Cammann, an instrument is worthless. An instrument must be very good, or it is without value. The knobs Fiu. 9. Allison's differential stethoscope which are to enter the ears must be of the right size; if they enter too far they occasion pain. The curves at the aural extremity must be such that the aperture is in the direction of the meatus of the ear. The flexible tubes must not be stiff, and their movements must be noiseless. All the tubes must be unobstructed, for it is the air within the tubes which chiefly conducts the sounds. In the use of the instrument it should be applied to the chest without any intervening clothing.1 1 The stethoscopes made by Tiemann & Co. and Ford & Co. are reliable.
