Finally, we have Elliss derivation from the Recto-vesical layer. This to my mind cannot be the case, for,as is indeed expressly stated by Quain, the fibres oforigin of the Levator ani muscle from the SymphysisPubis, are found distinctly, between the Eecto-vesicalfascia and the Posterior layer of the Triangular ligament. 166 A MANUAL OF DISSECTIONS. It is, however, a fact that the Rectovesical fascia closesthe Pelvis above these attachments of the Levatores ani, between the Pubo-prostatic ligaments of opposite sides,except in the centre, where it dips down to join theProstate, leaving a small interval ; but this makes anotherlayer closing the Pelvis just below the Symphysis, andwe have indeed from without inwards-.
