Calvarium of a Girl of the ancient British race, aged ahout 

 9 years. {Plate ~K1H., figures 1 and 2.) 



This is a calvarium of great size and of good form, show- 

 ing, by the state of the dentition, that the girl to whom it 

 belonged was not more than 9 years of age, if quite so much. 

 The permanent incisors and second premolars have not 

 been cut. 



The nasal bones are of good length, and the facial angle 

 considerable. The forehead is upright and broad, and the 

 whole calvarium is full and equable. The parietal protuber- 

 ances are decidedly prominent, and the interparietal diameter 

 great. It is a brachycephalic calvarium, manifesting great 

 cerebral development at so early an age, if it have not been 

 the subject of hydrocephalus, which is a little uncertain ; 

 and, although so imperfect, clearly indicating the cranial 

 characters of the ancient British race. A rather extensive 

 parieto-occipital flatness, I take to be the result of nursing in 

 infancy on the primeval cradle-board. 



The measurements, which, from the early age of the indi- 

 vidual, although so considerable, do not afford the means of 

 comparison with adult examples, are as follow : — 



Circumference . . . . . . 21*2 inches. 



Fronto-occipital arch . . 15'2 „ 



Length of Frontal . . . . 5-3 „ 



„ Parietals . . . . 4*9 „ 



„ Occipital . . . . 5*0 ,, 



Greatest width, which is interparietal 6*0 „ 



Width of Frontal . . . . 4-9 „ 



„ Parietals . . . . 5'7 „ 



„ Occipital . . . . 4" 5 „ 



Greatest height . . . . 5*5 ,, 



Height of Frontal . . . . 4'9 „ 



„ Parietals . . . . 5*0 „ 



„ Occipital . . . . 4-0 „ 



Proportion of the length, represented by 100, to the width 

 80-, and to the height 73-3 : — 



Length. Width. Height.
