Hardcover (Forgotten Books Jan. 21, 2019)
Excerpt from The Ear in Health and Disease: With Practical Remarks on the Prevention and Treatment of DeafnessThe human ear is composed of three distinct parts, - the external, or visible portion, with its auditory canal or mea tus - a contrivance intended to reflect into one focus the vibrations or sonorous rays of the atmosphere falling upon it in every possible direction; the middle portion - a bony cavity like a drum, covered on either side by elastic mem branes, and designed to transmit the impulses of sound; and the internal portion - the seat of the sense of hearing, consisting of a number of cavities lined by a membranous texture, on which the sentient extremities of the auditory nerves are expanded.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
