    excretory ducts open 'into the mouth on each side of the froenum linguce, or thread (bridle) of the tongue. The fluid may sometimes be seen jetting forth when the mouth is open, especially when the mind reverts to the eating of fruits. This and the succeeding or sub-lingual glands, have much the same use as the parotids.] SECTION 7. OP THE SUB-LINGUAL GLANDS. [The sub-lingual glands are situated under the tongue, within the lower jaw, one on each side of the thread of the tongue. They are small, elongated bodies, and lie immediately under the mucous membrane of the floor of the mouth. They have a number of mouths or ducts that freely discharge the fluid secretion of the glands.] SECTION 8. OP THE THYROID GLAND. [This is a small, flat, glandular body lying against the fore- part of the trachea, below the thyroid cartilage. It is suscepti- ble of great enlargement, and often is found enlarged more or less, especially in women. The disease is called goitre or bronehocele, and sometimes big-neck. The thyroid gland, though supplied with four large arteries and veins, as also with four nerves, has no excretory duct that has as yet been discovered; nor has there ever been any satis- factory speculation as to the use of the gland itself.] SECTION 9. OF THE PROSTATE GLAND. [This is a small gland, about the size of a chestnut, situated before the neck of the bladders behind the symphysis pubis, and surrounding the first portion of the urethra. Its excretory outlets, to the number of ten or more, open into the urethra, and afford a lubricating fluid to this passage.]
