NORMAL ANATOMY OF THE LIVER. 161 (triangular) are two triangular folds of peri- toneum which commence at each extremity of the posterior border of the liver and converge towards the termination of the broad ligament. They are broad near the extremities of the or- gan, and permit of a certain degree of motion in the right and left lobes, but become narrow as they approach the middle line. The two layers which compose the right lateral ligament separate as they pass inwards, and partly inclose an oval space (11, 11) of variable size, which is uncovered by peritoneum and in close con- tact with the diaphragm ; the remainder of the space is bounded by the division of the layers of the broad and left lateral ligaments. The peritoneum surrounding this space, with the contained cellular tissue, which is large in quan- tity and connects the posterior border of the liver firmly with the right leaflet of the central tendon of the diaphragm, constitutes the co- ronary ligament. The inferior vena cava (14) emerges from the liver at about the middle of this space previously to its passage through the quadrilateral opening in the tendon of the dia- phragm. The left lateral ligament, near to its extremity, advances a little upon the upper sur- face of the left lobe. The round ligament, (Jig. 33, 12) (ligamen- tum teres, umbilicale) is a rounded fibrous cord resulting from the obliteration of the um- bilical vein of the foetus. It is contained in the anterior margin of the broad ligament, and may be traced forwards along the linea alba to the umbilicus, and backwards through the notch in the anterior border of the liver and along the longitudinal fissure to the posterior border, where it is connected with the coats of the inferior vena cava. Turning to the under surface of the liver we have to examine certain Jissures which divide this aspect of the organ into lobes; the fissures are five in number; the long
