General Considerations : Remarks on the Manner herein Employed of 

 Describing Skulls, together, avith an Explanation of Terms. 



In this section will be embraced : 



Novel or unusual measurements. 

 The prominence of the supra-orbital 



ridge and of chamreprosopy. 

 The orbit. 

 The nasal bones. 

 The nasal chambers. 

 The hard palate. 

 The guttural region. 

 The temporal fossa. 



9. The malar bone. 



10. The lower j aw . 



11. The norma verticalis. 



12. The norma occipitalis. 



13. Ontogeny and pasdomorphism. 



14. The texture of the skull. 



15. The functions determining the form 



of the skull. 

 Having proposed certain measure- 



(1). Novel or unusual measurements, 

 ments embraced in the tables, it is incumbent upon me to explain them. 



Inio-opisthionr I have conceived that to take the distance from the opisthion 

 to the inion, or posterior point of the occiput, is useful since it is a more accurate 

 measurement than the transverse occipital arc (which is omitted) and expresses the 

 important fact of the amount of occipital projection cp_iite as well. It is an approxi- 

 mation to the length of the base of the brain in the posterior cerebral fossa. It is 

 of course variable, the maximum in Seminole skulls being 67 mm. and the 

 minimum 44 mm. 



1 Moore Collection. 



2 The measurements of the occipital projection have been taken by craniologists irrespective of 

 attempting to correlate the figures with the length of the posterior cerebral fossa. See Wyman, Cleland, 

 Carr and Turner. The latter writer measures a " perpendicular radius " drawn upward from the 

 auditory meatus and adopts this as a base line.
