from the mucosa of the middle region of the stom- 
ach, the posterior border of the large stomach 
cavity; A is a longitudinal section through two 
ducts where they open to the surface; B is a 
similar section through the body of a gland below 
the region of the duct; C is a transsection through 
the bottom or fundus of a gland; all are drawn 
with a camera under the same magnification. 
As is seen in Figure 45, under low magnification, 
the duct is about one third of the entire length of 
the gland. The lumen of the duct is fairly wide, 
that of the body of the gland is reduced to a mere 
slit, while that of the fundus is quite wide. 
One, two, or possibly more, glands may open to 
the surface through one duct, as is shown in Figure 
46. There is nothing peculiar about the epithe- 
lium of these glands. Near the opening of the 
duct the cells are of a typical columnar character 
with finely granular cytoplasm, each with a nucleus 
at its basal end. 
In the deeper parts of the duct the cells become 
shorter until in the body of the gland (Fig. 46, B) 
they are cuboidal in outline. 
The bodies of the glands are so closely packed 
together that it is difficult to pick out an individual 
tube that will show details clearly enough to draw 
with a camera lucida. So far as could be observed 
all of the cells of this region of the gland are alike. 
The bottom or fundus of the gland, as seen in 
Figure 46, C, is somewhat enlarged and has a wide
