This is an OCR edition with typos. Excerpt from book: may bo dilated to fifteen or sixteen millimeters, but it gives way if the dilatation is carried beyond this point. It is, however, more dilatable than any other part of the urethra. Its axis describes a curve with the concavity directed upwards and forwards; this curve is slight in young subjects, but increases with age. The walls of the canal are in close apposition, one being anterior and the other posterior. The canal traverses the upper part of the prostate, so that it has much more of the gland below it than above. Its lining membrane is continuous with that of the bladder, and is thrown into longitudinal folds. On the floor of the canal is a narrow median ridge, from twelve to fourteen millimeters in length, rounded posteriorly, and more acute at its anterior or lower end; this is the crest of the urethra, and it is also called the verumontanum or caput gallina- ginis. At the fore part of this crest is a depression, within the margins of which are situated the openings of the ejaculatory ducts. On each side of the crest is a longitudinal groove, the prostatic sinus, into which the prostatic ducts open. Behind the crest, a slight elevation is continued backward through the neck of the bladder, into the uvula vesicae. The mucous membrane is covered by a flat laminated epithelium; it has on its outer side a layer of longitudinal muscular fibres, and these again are covered by circular fibres which are more marked above. A second layer of longitudinal fibres separates these latter from the substance of the prostate gland, which has on its outer side interlacing muscular fibres and a close plexus of veins. The thickness of the walls of this canal is a point of considerable importance, and it has been carefully studied by Mercier and others.
