MR. J. 1ST. LANGLEY ON THE HISTOLOGY AND 
sour, to acidulate) for those glands in the stomach which are differently called by 
different observers “fundus,” “peptic,” or “rennet” glands. It is only after great 
hesitation that I venture to employ a new term, but without a new term I find myself 
reduced to circumlocution or inaccuracy. That the present nomenclature is unsatis¬ 
factory scarcely needs to be pointed out. In the Rat there are no glands in the 
fundus of the stomach; in the Rabbit the glands of the fundus proper differ in some 
important points from those of the greater curvature, yet both are called fundus glands. 
The terms peptic and rennet glands are inappropriate, since the pyloric glands also 
secrete the peptic and rennet ferments. The terms “simple” and “compound” glands 
suggested by Ebstein* are applicable only to the gastric glands of Mammals, for it is 
only in Mammals that compound glands, i.e., glands possessing both border- and chief- 
cells, occur. 
The one characteristic point of the “ fundus,” “ peptic,” or “ rennet ” glands in all 
r animals is the secretion of an acid fluid. This characteristic is suggested by the word 
“ oxyntic.” 
In the Frog, then, the glands which produce the secretion active in gastric digestion 
are 
The oesophageal glands. The gastric glands. 
The oxyntic glands. The pyloric glands. 
The oxyntic glands have been most fully described by Partsch.! The epithelium 
on the surface of the mucous membrane and that in the mouths of the glands consists 
of long cylindrical cells, which in their outer portions contain nrucigen. Each cell 
is prolonged into a fine process. In the necks of the glands are found, in the upper 
portion, nearly cubical cells, in the lower portion two or three very marked mucous 
cells. In the body of the gland are the proper secretory cells ; they are rather irre¬ 
gular in form, but have a tendency to be ellipsoidal. When the cells are partially 
isolated after treatment with neutral ammonium chromate 5 per cent, they are fre¬ 
quently seen to possess a short prolongation corresponding to the process of a mucous 
cell of the surface. The cells on the opposite sides of a gland-tube are usually so 
arranged that the nucleus of a cell on one side faces the junction line of two cells on 
the other. (See Plate 77, fig. 10.) 
* Ebstein, Max Schultze’s Archiv., Bel. vi., s. 538, 1870. The words “ simple ” and “ compound ” are 
so commonly used to describe the form of glands, that it would probably lead to some confusion to use 
them for glands consisting respectively of one or of two kinds of cells. 
t Op- cit. The earliest account I have met with is that of Heidenhain, Max Schultze’s Archiv., Bd. vi., 
s. 394, 1870.
