The connection of the scala vestibula with the scala tympani, and this with the middle ear, is necessary for the passage of vibrations through the internal ear. Its liquids, being practically incompressible and surrounded on all sides by bones, could not otherwise yield to the movements of the stapes. *Detection of Pitch.*—The method of detecting tones of different pitch is not understood.
The Eustachian tube admits air freely to the middle ear, providing in this way for an equality of atmospheric pressure on the two sides of the drum membrane. The bridge of bones and the air in the middle ear receive vibrations from the membrana tympani and communicate them to the membrane of the internal ear. *Purposes of the Middle Ear. *—The middle ear serves two important purposes.
It receives the terminations of fibers from the auditory nerve and may be regarded as the true sense organ of hearing. The nerve fibers terminate upon the membrane known as the basilar membrane, which separates it from the scala tympani.
His mind shot far ahead, absorbing in one instance the writings of Hoffmann, whose imaginative tales kept the boy's mind in a continual state of nervous excitement. He was not content to climb patiently the mountain; he tried to reach the top at a bound. So he wrote overtures for orchestras, one of which was really performed in Leipsic a marvelous affair indeed, with its tympani explosions.
And no outrage upon the ear is in all this guttural B minor, no rape of exotic tympani, but a sense rather of superb languor and wholesome tranquillity, of harmonious stomachic socialism, an orchestration of honest ovens and a diapason of honest bräus and brunners, with their balmy wealth of nostril arpeggios and roulades.
*How We Hear.*—The sound waves which originate in vibrating bodies are transmitted by the air to the external ear. Passing through the auditory canal, the waves strike against the membrana tympani, setting it into vibration. From here the vibrations pass through the channels of the cochlea and set into vibration the contents of the scala media and different portions of the basilar membrane.
Extending across the middle ear and connecting with the membrana tympani on one side, and with a membrane closing a small passage to the internal ear on the other, is a tiny bridge formed of three small bones. Where the malleus joins the membrane is a small muscle whose contraction has the effect of tightening the membrane.
A phenomenon must be accounted for, and he who will not accept a theory offered, or even a word applied, is indebted in a full explanation. The rumour spread in long slow ripples, till at last one of them struck the membrana tympani of the laird, where he sat at luncheon in the House of Glashruach.
The "oblong marrow"; that portion of the brain which lies upon the basilar process of the occipital bone. Meibomian. A term applied to the small glands between the conjunctiva and tarsal cartilages, discovered by Meibomius. Membrana Tympani. Literally, the membrane of the drum; a delicate partition separating the outer from the middle ear; it is sometimes popularly called "the drum of the ear."
All the fiddles strummed With tuning up; the wood-winds made a ring Of reedy bubbling noises, and the sting Of sharp, red brass pierced every eardrum; patting From muffled tympani made a dark slatting
