the apex of the lambdoid suture forms a widely open angle. The 

 parietal tubera are well marked, and one of them is the seat of 

 an exostosis ; the walls of the skull below widen only very slightly 

 as they pass down to the mastoids ; the point however of maximum 

 width lies below that of the parietal tubera and on a level with the 

 posterior and superior angle of the squamous. A dilatation in 

 the line of an accidental fissure running about midway between 

 the upper and lower borders of the left parietal bone marks the 

 exact position of the parietal tuberosity of that side; which, as 

 is the rule in skulls of this type, is seen to be both further forward 

 and lower down than it, with the part of the brain which it 

 covers (for which see Huschke, 1. c. p. 142), would be in brachy- 

 cephalic forms. The upper lineae semicirculares for the origin of 

 the temporal muscles are plainly seen above the parietal tubera.

[xliv. 3. p. 198.] 



The calvaria and lower jaw, ' Weaverthorpe, xliv. 3,' may 

 firstly be taken to illustrate the fact that a type existed in the 

 Bronze Period which is recognisable amongst modern Celtic 

 populations ; and, secondly, may throw some light upon the various
