    The nature of this sound must be learned by experiment, for no verbal description can give a perfect idea of its character. 13. In crder to perform percussion systema- tically, the thorax is divided into distinct regions, and every region has its particular degree of sound. The Regions of the Thorax. 14. The external parts of the thorax are divided into fifteen regions, of which twelve are double, and three are single; as follows: I. The sub-cloidal region, is that part of the chest covered by the clavicles. When the clavicle is struck upon the sternal extremity, or towards its middle, it gives a very clear sound ; on the humeral portion the sound is rather dull. The knowledge of the natural and unnatural sound of this part of the chest is most impor- tant, inasmuch as it ordinarily furnishes the first signs of tubercles in the lungs. When the | clavicles are too far from or too close upon the chest, by reason of their being too arched or too straight, then the resonance is less; especially in the latter case.
