glands (larger tlian the buccal glands), situated between the buccinator
and masseter muscles, and having separate ducts, which have their
orifices near the third molar tooth.
The Palatine Glands are situated in the deep portion of the muco-
periosteum of the hard palate and under the mucous membrane of the
oral and nasal surfaces of the soft palate and uvula ; they are small,
round, racemose, or compound tubular glands, and form a continuous
layer upon each side of the roof of the mouth, but are absent in the
median line.
The Lingual Glands are of two kinds—the small racemose or com-
pound tubular and the simple tubular variety—situated under the
mucous membrane, principally on the posterior portion of the upper
surface of the tongue near the circumvallate papilhe and foramen
caecum, several of the ducts of the glands opening into the foramen.
Those which open near the circumvallate papillse, and Avhere the taste-
buds are situated, secrete a watery fluid instead of mucus, as was for-
merly supposed. These glands are also found under the mucous mem-

near its apex, a number of these glands are grouped together, forming a
small oblong mass having several ducts in a line, which open upon the
mucous membrane.
