small holes through which the nerves of smell pass. A 

 little bit of it is seen on the inner side of the eye-socket at 

 E in Fig. 26. 



Facial Skeleton. The majority of the face bones are in 

 pairs ; two only being single and median. One of these is 

 the lower jaw-bone or inferior maxilla (Fig. 26, Md); the 

 other is the vomer, which forms part of the partition 

 between the two nostrils. 



The paired face-bones are: 1. The maxillce, or upper jaw- 

 bones (Mx, Fig. 26), on on each side, carrying the upper 

 row of teeth and forming a great part of the hard palate, 

 which separates the mouth from the nose. 2. The pala- 

 tine hones, completing the skeleton of the hard palate, and 

 behind which the nose communicates by the posterior nares 

 (Fig. 27) with the throat cavity, so that air can pass in or 

 out in breathing. 3. The malar hones, or cheek-bones, 

 (Z, Fig. 26), lying beneath and on the outside of the orbit 

 on each side. 4. The nasal bones (X, Fig. 26), roofing in 

 the nose. 5. The lachrymal bones (L, Fig. 26), very small 

 and thin and lying between the nose and orbit. 6. The 

 inferior turbinate bones lie inside the nose, one in each 

 nostril chamber. 



The Hyoid. Besides the cranial and facial bones there 

 is, as already pointed out, one other, the hyoid (Fig. 28), 

 which really belongs to the skull, although it lies in the 

 neck. It can be felt in front of the throat, just above 

 " Adam's apple." The hyoid bone is U-shaped, with its 

 convexity turned ventrally, and consists 

 of a body and two pairs of processes 

 called cornua, The smaller cornua (Fig. 

 28, 3) are attached to the base of 

 the skull by long ligaments. These

 of the skull much as the ribs are attached to the bodies of 

 the vertebra?. In fishes, behind this hyoidean arch come 

 several others which bear the gills; and in the very young 

 Human Body these also are represented, though they almost
