I think I have quoted enough to justify the state-ment that the connections of the Posterior layer of theTriangular ligament may well be a stumbling block, forwe have the following different accounts given:— 1.

ThePubo-prostatic ligaments are above the Levatores ani muscles. TRIANGULAR LIGAMENT OF THE URETHRA. 165 2. The white line extends from the lower part of theSymphysis Pubis. Therefore the Triangular ligament must be below thelevel of the Pelvic fascia, which only extends as far downas the whi
