Our lungs, trachea, and larynx are formed from the ventral wall of the branchial gut. These vesicles are found in all the Vertebrates except the two lowest classes, the Acrania and Cyclostomes. In the lower Vertebrates they do not develop into lungs, but into a large air-filled bladder, which occupies a good deal of the body-cavity and has a quite different purport.
The funnel-shaped cavity beyond, into which both the mouth and the posterior nasal passages open, is called the pharynx. In its lower part are two openings; the trachea, or windpipe, in front, and the oesophagus behind. The trachea is surmounted by a box-like structure of cartilage, about four and one-half inches long, called the larynx.
Guattani mentions a curious instance in which a man playing with a chestnut threw it in the air, catching it in his mouth. The chestnut became lodged in the throat and caused death on the nineteenth day. At the autopsy it was found that an abscess communicating with the trachea had been formed in the pharynx and esophagus.
Gruber, Dr., on the occurrence of the supra-condyloid foramen in the humerus of man; on division of malar bone; stridulation of locust; on ephippiger.

Guanacoes, battles of; canine teeth of.
The cartilage closing this opening is pressed shut by the base of the tongue when the bolus of feed is passed back and into the oesophageal opening. The larynx may be compared to a box open at both ends. The several cartilages that form it are united by ligaments. It is lined by a mucous membrane. The posterior extremity is united to the first cartilaginous ring of the trachea.
The autopsy proved beyond a doubt that the murdered man had been dead for many hours before the discovery of his body. The bullet which had struck him in the back had pierced the trachea and death had occurred within a few minutes. The only marks for identification of the body were the initials L. W. on his underwear.
The trachea of the domestic fowl was especially designed for the purpose, only the necessary attachment for getting a firm grip on it was accidentally omitted." "It certainly was." Charlotte tugged away energetically for a moment, and drew out the windpipe successfully. The doctor regarded the bird with a quizzical expression.
The pleura is not much reddened, but by its thickness in some points, its adhesion in others, and the effusion of a serous fluid, it proves how much and how long it has participated in the inflammatory action. The trachea and the bronchia are slightly red, and the right side of the head is gorged with blood.
Now, therefore, we do trustfully petition that this wearisome psalm-sharp, this miauling meter-monger, this howling dervish of hymns devotional, may strain his trachea, unsettle the braces of his lungs, crack his ridiculous gizzard and perish of pneumonia starvation. And may the good Satan seize upon the catgut strings of his tuneful soul, and smite therefrom a wicked, wicked waltz!
The Dominie was grave and irascible, but he possessed a fund of drollery and the kindest heart. His features could not laugh, but his trachea did. The chuckle rose no higher than the rings of the wind-pipe, and then it was vigorously thrust back again by the impulse of gravity into the region of his heart, and gladdened it with hidden mirth in its dark centre.
