Book Description

Excerpt from A Practical Treatise on the Physical Exploration of the Chest, and the Diagnosis of Diseases Affecting the Respiratory Organs An original feature of the work is the introduction of several signs produced by the whispered voice. These signs, as representing certain physical conditions, are generally available, and their char acters relating to pitch and quality are highly significant. The names exaggerated bronchial whisper, whispering bronchophony or bronchophonic whisper, and cavernous whisper, although, perhaps, not, intrinsically, the best which might have been devised, have the advantage of corresponding with the names commonly applied to correlative signs produced by the loud voice. The author would state, as a feature of the work, the recognition of the principle that the constancy of association of certain ab normal sounds with certain physical conditions constitutes the only reliable proof of the validity of the former as representing the latter. It is inconsistent with this principle to undertake to determine a priori signs to which certain physical conditions should give rise, and still more, on the other hand, to infer the existence of certain i physical conditions from certain abnormal sounds. As stated in the preface to the first edition, To the mechanism of physical phevi preface. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
