similar portions of the stomachs of other mammals. ‘The cells are 
elongated conical structures. A well-defined mucous theca occupies 
the outer third of the cell, an oval nucleus the inner protoplasmic por- 
tion. Passing down the sides of the foveole there is observed a gradual 
reduction in size, from cell to cell, of the mucigenous border, and for a 
variable distance at their lower ends foveole are lined by columnar 
cells in which only a very narrow band of mucin can be distinguished 
along the free border. The spherical or oval nuclei of these cells are, 
as compared with the nuclei of the cells of the surface epithelium and 
those of the glands, exceedingly rich in chromatin and are frequently 
seen in the process of mitotic division, from one to four or even more 
mitoses being seen in each foveola. Many leucocytes, both lymphocytes 
and polymorphonuclear cells, could be seen in my material, within the 
epithelium of the foveole, in most cases occupying spaces between the 
cells but occasionally intracellular. 
For a short distance at their upper ends, the glands are lined by cells 
similar in all respects to those of the deep ends of the foveole, but at a 
short distance from the foveola the cells begin to give evidence of 
greater activity in secretion inasmuch as the portion of tlie cell so en- 
gaged increases in size and the protoplasmic portion containing the 
nucleus becomes correspondingly reduced. This feature becomes more 
and more prominent as the bottom of the gland is approached, where the 
cells may be entirely filled with secretion. In such cells the nuclei 
are compressed, flattened or crescentic, and are found at the base of the 
cells. As a rule, there is considerable variability in the cardiac glands 
as to the degree of loading exhibited by the individual cells of a terminal 
tubule or of different terminal tubules, some cells being completely 
filled with secretion, others only partly so. In the latter type, the cell 
is sharply divided into two zones, a proximal protoplasmic zone in which 
a fine reticulum may be seen, and a distal zone which appears transparent 
in ordinary preparations and contains the stored-up secretion (Fig. 3, A). 
The outer zone does not contain basal filaments, nor is it markedly 
chromophile. Examined for masked iron by the usual methods, a 
slight reaction is obtained, but no greater than that exhibited by the 
protoplasm of the cells of the surface epithelium, the pyloric gland 
cells, and the neck chief cells of the fundus glands. The inner zone 
of these cells stains but faintly in hematoxylin and eosin, but one can 
readily recognize a wide-meshed alveolar structure, the meshes of which 
correspond to the protoplasm between the droplets of secretion. The 
apparent thickness of these protoplasmic meshes is increased by the 
precipitation on them of the solids of the secretion. Frequently the
