TEAGBEAL DIVERTICULA 617 The mucous membrane of the guttural pouches is directly con-tinuous with that lining the Eustachian tubes. The pouches them-selves appear as large saccular dilatations of the terminal ends ofthe tubes, and for this reason they are termed by some writers theEustachian pouches. Each pouch opens into the pharynx immediatelyabove the soft palate by a valvular orifice ; one side of the valve isformed by the leaf-like termination of the Eustachian tube. Of thefunctions of these pouches nothing is known. They are often a sourceof inconvenience to horses, for the mucous membrane is very prone tobecome inflamed, and the scanty outlet for the secretion leads to its.

When enlarged inthis way they may have a capacity of six or more ounces each. Theretained secretion may decompose, and the sac become distended withpus, which is discharged at intervals through the nose ; or the pharyn-geal orifice may be occluded, and the pouches enlarge to such an extentas to require an incision through the skin of the neck or through themouth. Not infrequently the contents of the pouches become inspissatedand formed into concretions. These are of different shapes and sizes,and vary in number from one, two, or three to fifty or even they are of an oval shape ; not seldom they resemble consistence these concretions are like cheese, and on section have alaiuinated appearance.
