111 noniia facidlis tlic frontal hone appears low and sharply receding; the 

 orbits are medium-sized and (juadrangular ; the superior orbital margin is some- 

 what more posteriorly situated than the inferior. The lacrimal bones are, as a 

 rule, produced forward beneath the opening of the lacrimal canal, to take part 

 in the formation of the inferior orbital margin, sometimes with the interposition 

 of a small, distinct, bony ossicle. (See fig. ^&.) Posteriorly, the orbit 

 is well closed closed in, and the inferior orbital fissure narrow. Frequently one 

 finds the malar bones excluded from the fissure bv a frontosphenoidal suture, 

 and this is always the case wdiere the infraorl)ital suture is patent — a not un- 

 common condition. 



On both sides of the prominent subnasal spine are usually shallow praenasal 

 fossae, and the lower margins of the nasal aperture are definitely double with an 

 infantile appearance, or may even be pithecoid. The alveolar margins arch 

 forwards and outwards to overhang the broad, deeply-set palate. 



Norma basilaris : The foramen magnum is large and oval ; the pterygoid 

 processes broad antl low; the postnasal spine short and broad; the palatine 

 suture irregularly cruciform ; the palate itself long, broad, deep, and horseshoe- 

 shaped. 



In other words the norma basilaris appears to be not at all influenced liy the 

 deforming process that so grossly changes the skull as seen in its lateral and 

 vertical projections. 



The skull capacity does not appear to difi'er from that of normal specimens, 

 the disposition of the contents merely being altered, so tliat the excess in height 

 and length is made up at the expense of the frontal and occi|)itaI prominences. 



The skull is brought finally to a condition of hypsisteno-dolichocephalus 

 artificialis. but as age advances tends more and more to regain the shape from 

 w hich it was originally distorted. 



The main indices are : 



Cephalic: (i| 6o-2. (2) 68-4. 1 ;, ) (,97, (4) 737, (^5) 68-3. 

 Gnathic : ( Flower ) , 106 '4 

 Orbital : 85 -9. 

 Nasal : 47 '3. 

 Palato-maxillary : 85 T. 



In general, then, the skulls are: 



Hypsistenodoliclioce])halus artificialis, prognathous, mesose'me, leptorrhine, 

 and dolichuranic. with a cranial capacity ranging between 1 185 cc. and 1340 cc.
