hepatic tissue. The left lateral fissure, complete, between 

 the left (lat.) and left mesial lobes (shown in diagram) 

 measures 8 cm., and between its extremity and the dorsal 

 margin are 5 cm. of hepatic tissue. On this aspect we are 

 struck by the large relative size of the mesial or cystic 

 lobe to the right of the suspensory ligament, which 

 laterally measures 12 cm., while on the left it only equals 

 5.5 cm. Three portions of the cystic or mesial lobe are 

 described, viz., large right mesial, small left mesial, and 

 the insignificant intermediate mesial (lobus quadratus). 

 Only a remnant of the cystic or mesial fissure (i.e., between 

 the intermediate and left mesial lobes) is seen, and 

 measures 2 cm. To it the suspensory ligt. runs from the 

 inf. v. cava. Anteriorally it becomes part of the gall 

 bladder cleft, which is 2.5 cm. long, and .5 cm. laterally. 

 The gall bladder is seen projecting on the two surfaces of 

 the liver. Between the cystic fissure and the gall bladder 

 cleft is a triangular projection, the remains on this aspect 

 of the intermediate mesial lobe (i.e., lobus quadratus). 

 It measures 3 cm. long, and 2.5 cm. laterally, i.e., it has 

 almost disappeared. The left mesial will fuse, as has 

 partially happened on the visceral surface, to the left 

 (lat.) lobe; and the suspensory ligt. will pass to the gall 

 bladder fissure with the final disappearance of the inter- 

 mediate mesial lobe. 



(Specimen F.) 



Diaphragmatic Surface. — The liver measures later- 

 ally 14 cm., and the right and left lateral fissures, i.e., 

 between the mesial or cystic lobe and the right and left 

 (lateral) lobes have practically disappeared, being only 

 represented by fissures about 1.25 cm. long. Interest 

 chiefly centres round the ventral portion of the mesial 

 or cystic lobes. We distinguish firstly on the right the 

 cleft for the gall bladder, 4 cm. dorso-ventrally, and 2 cm.
