XIV F-8 



The skull of a child, badly damaged. An attempt has been made to recon- 

 struct the skull, but the relative positions of the cranial bones are unsatisfactory. 

 No measurements have therefore been attempted. 



The temporary molar teeth are all present but the others have been lost, 

 though their alveoli are intact. The permanent molars had been still under- 

 neath the gums, thus placing the age of the skull at about 5 years. 



XIV F-9 



• 



The hard palate of an aged individual, much weathered and bleached, with 

 patches of moss growth here and there. The dental alveoli of the left side, from 

 the lateral incisor to the first molar inclusive, had become completely absorbed, 

 as also that for the first premolar of the right side. The palato-maxillary index 

 could not be estimated. 



XIV F-10 



Fragment of the occipital bone surrounding the foramen magnum. The 

 basi-occipital and the jugular processes had been connected to the neighbouring 

 bones by an intervening layer of cartillage, so that the individual must have 

 been under twenty-five years of age. 



XIV F-11 



The mandible of an adult slightly weathered and decayed. The three left 

 molars are the only teeth left in the jaw, and are much worn but healthy. The 

 other alveoli had been occupied, as their walls are of normal depth. The right 

 central and the left lateral incisors had never erupted, and the alveolar border 

 of the jaw is heaped up over the sites of their sockets. The angle of the mandible 

 is very obtuse — measuring 128°. The grooves for the lingual nerves are well 

 pronounced.
