Itis narrower than any other part ofthe urethra, except the meatus, andin consequence of the greater devel-opment and number of muscular tis-sues surrounding it, possesses in ahigher degree the power of contrac-tion. This characteristic has ledsome authors to give it the nameof the muscular region of theurethra. The spongy urethra, inclosed in theerectile tissue of the corpus spon-giosum, varies in length accordingto the degree of turgescence of the o/fiw/penis; in a state of relaxation, itusually measures about five inches;during erection, it may attain sevenor eight. The posterior portion ofthis region is somewhat dilated, es-pecially on its inferior aspect, andhas received the name of the sinusof the bulb. The term bulbousportion is also applied to the pos-terior inch of the spongy urethra.The ducts of Cowpers glands opennear its centre. Besides being some-what dilated, the sinus of the bulbis extremely dilatable. This may Cowpei** GhmZ.

The difference in the size of the part corre-sponding to the bulb will exhibit the dilatability of which it issusceptible. Wood-cuts of two casts thus taken may be found inthe London Lancet (Am. ed.), Aug. 1851, p. 97. Anterior to its sinus,the spongy portion maintains a nearly uniform diameter until withinabout an inch of the meatus, where it again enlarges and forms thefossa navicularis. Lastly, the external orifice or meatus is anarrow vertical slit, which is the most contracted part of the wholecanal. I
