When the cavity is of very large size, and under circumstances favourable to the production both of the amphoric sound on percussion and amphoric respiration, the resonance of the voice and cough is attended with still further modifica- tion. When the patient speaks, the voice, instead of being close to the ear and articulate, as in pec- toriloquy, has more the character of broncho- phony, but is hollow and metallic, and from re- sembling the sound produced by speaking into an empty vessel, is termed amphoric. Precisely the same quality of sound attends coughing, and the amphoric cough and voice will generally be found together. On the whole, they are of more value than the cavernous, being not only more peculiar, but impossible of imitation in any healthy condition—and, under favourable circum- stances, more constant in occurrence. There are but two pathological states which can produce these amphoric sounds,—viz. large vomicae, and pneumothorax ; but with the aid of other signs, and the history of the case, one can rarely be
