    The second division of the urethra has received the name of the membranous portion. Its direction is oblique like that of the preceding, and its length from nine to twelve lines. Its parietes are delicate and consist of two coats; the internal one, thin, elastic, and of a reddish hue, having all the characters of a mucous membrane; the external, more dense, firm, white, and extensible. The membranous portion of the urethra corresponds below and behind to the rectum with which it is connected by a quantity of cellular substance, and ahovp and before to the inferior part of the symphisis pubis. The remainder of the urethra consists of a single division, called the spongy portion, and is one of the constituent parts of the penis. It is from six to seven inches in length ; the upper part of its external surface is lodged in the groove formed by the corpora cavernosa, and the rest is covered by the common integuments. This portion of the urethra com- mences at an oblong pyriform expansion, and terminates at an other which constitutes the gland. From the bulb to the gland the urethra presents an uniform cylindrical cavity ; this becomes larger within the substance of the gland to form the fossa navicularis ; this again grows much narrower and ends at the apex of the gland in an oblong aperture. The spongy portion of the urethra consists of two membranes, the external of which is thick and cellular, and known by the name of the corpus spongiosum; the internal is a mucous membrane of great delicacy and; tenuity, on the surface of which are numerous follicles which discharge a lubricating fluid. The extent of the urethra is not the same in all per- sons, and writers on anatomy have manifested much di- versity of opinion on this subject. In some works we
