    pneumothorax exists, or large cavities are present in the lungs, it may be accompanied by metallic tinkling and amphoric echo. If fluid, mucus, or other matter be present in the air-passages, it may be attended by rales and ronchi, which, just as with respiration, will vary, cceteris paribus, according to the sizes of the passages or spaces in which they take their origin. In short, tussive resonance affords little or no information which may not be derived from the voice and the respiration; and in an auscultatory point of view, cough acquires its importance, not from the peculiar resonance which it produces, but from its power of removing mucus or other matters by which the air-passages are apt to become obstructed. Cough consists of a sudden and forcible expiration, followed by a quick, yet deep inspiration. The suddenness and force of the expiratory effort is often such as to dislodge obstructions in the bronchi, which cannot be got rid of in any other way; and thus a passage is cleared for the free ingress of air during the deep inspiration, by which each paroxysm of TABLE RESONANCE OP THE VOICE, AS HEAED OVER THE Variety.

The sound is loud and concentrat- 1 ed, in the highest degree, conveying the idea of being produced immedi- ately beneath the stethoscope, and of passing through the instrument so as to strike directly and forcibly - on the ear The sound is less loud, less con- centrated, and less distinctly arti- culated than in tracheophony: it appears to be produced at a greater distance, to be more diffused, and to strike less distinctly against the ear, so that the words seem to be at the end of the instrument instead of - passing through it into the ear A diffused vibratory sound, amounting to little more than a humming or buzzing, and convey- ing the impression of distant origin.
