for a day or two, and then, after removal of the 

 pia m'ater, in strong alcohol (see note, p. 46). 

 XVII. Place the animal again in the supine position, 

 and make out in the abdominal cavity, without 

 cutting or tearing anything : 



165. The characters of the liver: its convex anterior 

 surface applied to the diaphragm, its concave posterior 

 surface against which the stomach fits, its attached dorsal 

 and free ventral borders. The dorsal border is attached by a 

 thin sheet of peritoneum, the coronary ligament, to the 

 dorsal part of the posterior surface of the diaphragm : a 

 median vertical sheet of peritoneum, the suspensory 

 ligament, connects the anterior surface of the liver with 

 the posterior surface of the diaphragm. This latter ligament 

 divides the liver into a right and left segment; each 

 segment is again divided into lobes, of which there are, on 

 the right side, the ventral right central lobe (Fig. 60, 

 p. 301, r.c), and the dorsal caudate lobe (cau) closely 

 applied to the right kidney ; and on the left side, the 

 ventral left central lobe (l.c\ the dorsal left lateral 

 lobe (/./) fitting against the left anterior region of the 

 stomach, and the small Spigelian lobe (spg\ fitting closely 

 into the lesser curvature (see 168) of the stomach. 



1 66. The gall bladder, a green pyriform sac, embedded 

 in the right central lobe of the liver. 



167. The oesophagus, or gullet, a narrow tube emerg- 

 ing from the thorax through an aperture in the diaphragm, 

 dorsal to the liver, and entering the Stomach. 



1 68. The stomach, divided into a large cardiac portion 

 to the animal's left, and a smaller pyloric portion to the 

 right side ; its posterior greater curvature, and anterior 

 lesser curvature ; the cardia or entrance of the ceso- 

 phagus towards the left of the lesser curvature, and the
