The corpus spongiosum terminates anteriorly in anexpansion, called the glans penis; while a thin layer of erectiletissue is continued backwards around the membranqus portion ofthe urethra and extends into the veru montanum of the prostate.

The accompanying diagram, drawn by Mr. Thompson from a dis-. section upon the dead body, exhibits the depth and position of thebulb, and its relation to the rectum; a matter of no small impor-tance with reference to operations upon this part. The corpus spongiosum consists of a vast number of venoussinuses, communicating with each other in all directions. Its greatvascularity explains the hemorrhage which is liable to ensue, whenthe spongy, and also the membranous, portion of the urethra isdivided by the knife of the surgeon or accidentally wounded. Thisoccurrence, however, is less likely to take place, when an incision isconfined to the mesial line; either in consequence of the fibrouspartition which separates the two lateral portions of the vasculartissue at this point, or, as suggested by Mr. Thompson, because thetwo branches of the pudic artery, which lie one on either side, arethus avoided. The corpora cavernosa are two in number. Arising in front of thetuber ischii, and intimate
