The deep facial group of lymphatics has its origin in the temporal
lossa, the orbital and nasal cavities, and the mouth. Some of the lym-
phatic vessels of the brain-case emerge through the oval and spinous
foramina in the sphenoid bone and join this series of lymphatics. All
of the vessels constituting this series then pass outward along the course
of the internal maxillary vein, and enter the glands in the neighborhood
of the angle of the inferior maxillary bone.
