sutures. The temporal ridge or crest was double on both sides 

 in No. 147, — a distinct interval, a quarter of an inch in width 

 intervening between the two ridges. 



In eight crania Wormian bones were present towards the 

 asterionic end of the lambdoidal suture. In the supra-inionic 

 region one skull (245) was narrow and pointed; another (308) 

 projected distinctly backwards, and in two others (353 & 219) 

 this region was more prominent on the left side than on the 

 right side. 



The pterygo-spinous ligaments were ossified into distinct 

 bony plates in No. 286. In No. 349 there was pronounced 

 arching of the hard palate. In No. 353 the left jugular process 

 of the occipital bone was prolonged downwards nearly as far as 

 the mastoid process. 



In No. 354 the tympanic element of both temporal bones 

 was markedly prolonged downwards, forwards and inwards in 

 such a manner as to form a vaginal process which considerably 

 obscured the outer aspect of the base of the styloid process, and 

 also extended between it, on the one side, and the jugular 

 foramen and carotid canal on the other. The hinder part of the 

 glenoid fossa was narrow in the antero-posterior direction, while 

 there was marked irregularity of the articular surface in the 

 form of a distinct depression towards its outer end. In one 

 skull (286) the bridge of the nose was unusually flattened and 

 in another (499) it was exceptionally arched. In several skulls 

 the superciliary ridges were extremely prominent and overhanging. 



Discussion and Comparison. 



I have not considered it necessary to discuss in detail the 

 facts recorded in Table I, first because the number of crania 

 is scarcely large enough for purposes of wide generalisa- 

 tions, and second because my object was to deal with a special 

 set of measurements. Therefore in what follows I shall content 

 myself with the discussion of the results obtained by using the 

 segmenting callipers, and compare them with those already
