order that its insertion may be more apparent. The muscle descends 

 from its origin at the inner aspect of the hip-bone, and is inserted into coccyx 

 along the middle line from the coccyx to the central point of the 

 perineum. The hindmost fibres are attached to the side of the jt ; 

 coccyx ; and between that bone and the rectum the muscles of 

 opposite sides are united in a median tendinous line. The middle

This muscle bounds the ischio-rectal fossa on the inner side, and 

 unites with its fellow to form a fleshy layer (pelvic diaphragm), con- 

 vex downwards, through which the rectum is transmitted. On the
