    branous part of the urethra is much the deepest, the recollection of which, is all-important in lithotomy, as it teaches us to avoid the one, and to cut into the other. It may also be observed, that the hole in the triangular ligament is an inch below the symphysis pubis. By removing the upper corner of the triangular ligament, we are made acquainted with another just behind it, which is totally distinct. This ligament is half an inch broad, is thick and strong, particularly at its lower edge, and is very firmly attached laterally to each of the ossa pubis, just below the symphysis : it is a continuation of the liga- mentous union of the symphysis pubis. Mr. Colles calls it pubic ligament with great propriety. I would suggest, as somewhat more expressive, the term Inter-Pubic Ligament •* as it serves to distin- guish it from another called Pubic, which is above the pubes, and described in the account of the recti abdominis muscles. The breadtli of this having been stated at half an inch, it is obvious that the hole in the triangular ligament is half an inch below its lower edge. Pelvic Fascia. The Pelvic Fascia [Aponeurosis Pelvica) connects the bladder to the sides of the pelvis. This fascia descends from the ileo-pecti- neal line to about midway in the depth of the pelvis; here it is re- flected from the surface of the muscle, (the Levator Am,) and applies itself to the prostate gland and bladder on the body of which it is ultimately lost. At the angle of its reflection, this fascia appears par- ticularly strong and white, but becomes more weak and thin as it lines the muscle and covers the bladder. In tracing this membrane it will be seen that from the pubes just below the symphysis, a point- ed production of it, constituting its anterior margin, is fixed into the side of the neck of the bladder. This pointed production on each side is called, by most anatomists, the anterior ligaments of the bladder. Between them, just beneath the symphysis of the pubes, a pouch large enough to receive the end of the finger, is formed by the union of the fasciae of the two sides: this pouch connects the middle anterior part of the neck of the bladder to the lower margin of the symphysis pubis.f This fascia adheres closely to the periosteum of the pubes, between the upper margin of the thyroid foramen and the crista of the pubes; * See Symphysis Pubis. f Colles' Surgical Anatomy.
