no. 6 is the pyloric orifice, and 3, 4 the narrow openings at either extremity of the 
passage or diminutive cavity (*), through which a style is passed ; p.d, pancreatic 
duct joining; d.ch, the ductus communis choledochus. The latter enlarges within 
the intestinal wall, shown by the dotted line, and pierces the inner coat of the gut at 
no. 7; duo, duodenum, smooth above, and with valvule conniventes below. 
Fig. 33. Semidiagrammatic view of the liver, stomach, spleen, and part of the mesen- 
tery in their natural positions after removal from the abdomen, the stomachs 
being distended. Part of the lettering applies as in fig. 32. The dotted 
lines upon the surface of the gastric cavities give the places of attachment 
of the great omentum, which has been removed. 
L, liver; ¢.l, coronary ligament ; J, % modicum of the jejunum; Me, mesentery ; gl, 
glands thereon; Sp, spleen; Pa, pancreas. 
Fig. 34. Greatly reduced view of the under or postabdominal surface of the liver: r.J, 
round ligament; v.c, vena cava; h.a, hepatic artery ; h.v, hepatic vein. 
Fig. 35. Spleen, seen on its free or ventral surface. 
Fig. 36. Right kidney partially dissected, showing the distribution of the vessels on its 
atlanto-mesial side. Renal artery, a, and vein, v. 
Fig. 87. A few of the lobular acini of the kidney, of their natural dimensions. ‘The 
connecting fibrous envelope has been removed. 
Fig. 38. A renal lobule bisected, to exhibit its internal structure. N. at. size. c, cortex; 
m, mammilla; h, hilus. 
Fig. 39. Suprarenal body, reduced in size to correspond with the kidney, fig. 36, and 
placed somewhat in the natural relation it bears towards it.

Fig. 40. A side view of one of the vascular glands of the neck, drawn + nat. size. 
Px, cut plexus of vessels. 
Fig. 41. A mesial section of the same, the letters agreeing. 
Fig. 42. Small portion of the cesophagus, displaying the longitudinal ruge and a 
glandular crypt, gl, of nat. size. 
Fig. 43. A vertical transverse section of the cesophageal wall, and cut through one of 
the glandular fosse. The relative natural height of the ridges, depth of the 
furrows, and thickness of the muscular and mucous coats are preserved. 
g!, glandular crypt; m, mucous and submucous coat ; @, longitudinal layer of muscular 
fibres; c, cross fibres or circular layer. 
Fig. 44. Portion of the duodenum with agminate patch: P.gi, Peyer's glands; V.co, val- 
vulz conniventes. 
Fig. 49. Another piece of the jejunum, where Peyer's glands (P.g/) are elongate and 
narrow: /.f, the longitudinal folds.
