UPON THE BUCCAL GLANDS OF DOMESTIC MAMMALIA. 
* 
By B. Bakner. 
The macroscopic dispositions of the buccal glands vary 
considerably in different species of our domestic mammalia. 
These differences, which are not mentioned in our books of 
anatomy, are as follows: In ruminants, and especially the ox, 
there exists three buccal glands, one dorsal, one median, and 
one ventral. In the cat as in the dog, the dorsal gland occu¬ 
pies the orbital cavity, and for this reason is called the orbital 
gland. In the pig, the buccal dorsal gland is not covered by 
the matter. These glands also differ in size, according to the 
species, being largest in ruminants. 
The histological study shows that the buccal ventral 
gland in ruminants is an albuminous gland, furnishing a pro¬ 
duct of amylolitic secretion. In this it is classed with the 
parotid. 
The dorsal median gland of the ox, with the orbital and 
the buccal glands of the carnivora, are pure mucous glands. 
Yet the fluid from these glands possesses a saccharifying 
property very well marked, especially in ruminants. They 
are, from a physiological point of view, mixed glands. 
The dorsal and median buccal glands of the sheep and 
goat are distinguished from those of the ox by their cells, 
which are not evenly mucous. They are either more or less 
so, or not at all. However, it doesn’t appear that they ought 
to be altogether considered as mixed, but more as mucous 
glands subject to variations in their functions. 
The buccal glands of the horse and those of swine resem¬ 
ble those of the sheep more than those of the ox, but differ 
from them in some of their characters. They are special 
mucous glands in which the functional variations and the 
division of labor are carried to a fine point. They produce, 
also, besides mucine, an amylolitic ferment. 
In relation to the mucous richness, the buccal glands of 
the carnivora occupy the first place, and then comes the ox 
with his dorsal and median glands, and then the swine. The 
sheep, goat and horse occupy the lowest rank.— Ibid.
