saccular and the tubular parts of the stomach : these terms giving 
some idea of their form. The saccular portion lies dorsal to and 
to the left of the entrance of the oesophagus : its greatest diameter 
is 57 mm. The comparative narrowness of the tubular part is 
best indicated by saying that its greatest diameter is only 20 mm. 
It is placed ventral to and to the right of the oesophageal opening, 
and is abruptly bent upon itself at no great distance from the 
pylorus. As far as this bend it is only slightly curved, and passes 
in an oblique direction ventralwards and a little to the right. The 
abruptness of the bend causes the pyloric portion of the stomach 
to take a direction towards the vertebral column, and brings the 
pylorus within a comparatively short distance from the oesophagus. 
Not very far removed from the pylorus a constriction is noticed on 
the surface of the stomach ; this marking off a slight dilatation 
adjacent to the pylorus (PI. I. fig. 1 p.c.). The position of the 
pylorus itself is indicated to the eye by a very conspicuous con- 
striction, and to the touch by a thickening of the wall. 
Owing to the degree of approximation of the oesophagus and 
pylorus, the difference, in extent, of the two curvatures is con- 
siderable. The greater curvature is, at first, directed dorsally ; 
then it turns round to the left and finally to the right. This 
curvature is indented by a deep notch which marks the point of 
junction of the saccular with the tubular portion. The lesser 
curvature looks towards the vertebral column ; is confined to the 
tubular part ; and is most acute where the sudden change in 
direction of this portion of the stomach takes place. 
The “hepatic” surface looks almost entirely cephal wards. 
Though this surface may be called “ hepatic ” for convenience, it 
should be stated that the greater part of the saccular portion is 
not in contact with the liver, but with the diaphragm. The line 
(xxxxxxx) in PL I. fig. 1 shows the extent to which the stomach 
contacts the liver. 
Although the arrangement of the peritoneum will be described 
later, the gastric attachment of the great omentum may be 
mentioned here. The tubular portion has the omentum attached 
to its greater curvature, but in the saccular part the line of 
reflection of the omentum crosses the caudal surface of the 
stomach obliquely.
