SKILLS. 



( 'iili'n- ( 1 /mi-it /i. ( hving to the fragile condition of the skulls the 

 capacity was taken with mustard seed. Six of the crania were in a 

 sufficiently good state of preservation to admit of the internal capacity 

 being taken fairly accurately. The maximum capacity in five male 

 skulls is l,i)8() c.c., the minimum is 1 ,420 c.c. and the mean is 1, 400 c.c. 

 One female skull has a capacity of l,4GO c.c. Turner -jives 1,478 c.c. 

 as the mean capacity of seventy-three modern Scottish male skulls, and 

 1 ,:>'J2 c.c. as the mean of forty-two female skulls. So that the capa- 

 city of the short cist skulls does not fall much short of that of the 

 average modern Scottish skull. On the other hand the mean capa- 

 city of three modern male skulls of natives of Aberdeenshire is 1,~>9f> 

 c.c. a distinct increase. 



Lciitftli. The mean glabello-occipital length of eight male skulls 

 is 180'3 mm., and of two female skulls 17- mm. Both these measure- 

 ments are distinctly less than the corresponding measurements of 

 modern Scottish skulls. 



ll<'i<ilit.~ The mean basi-bregmatic height of eight male skulls is 

 139-3 mm., the mean for the modern skull being 132'4 mm. One 

 female skull has a height of 128 mm. 



The mean height of the cist skulls is very distinctly greater than 

 that of the modern skull. One cist skull has a height of 148 mm. and 

 another a height of 140 mm., measurements greater than the maxi- 

 mum height of 145 mm. recorded for modern Scottish skulls. 



Vert'icul Indr.r. The mean vertical index for eight male skulls is 

 77'3, while the index for one female skull is 74/4 the corresponding 

 figures for the modern skull are 70'9 and 70'5 respectively. Of the 

 nine skulls eight are practically hypsicephalie or high skulls, two 

 skulls having vertical indices over 80. 



lirt'ddth. In the eight male skulls the maximum breadth varies 

 from 160 mm. to 142 mm., the mean being 153'8 mm. as compared 

 with a mean breadth of 149 - 3 for modern Scottish crania. The mean 

 for the two female skulls is 142-5 mm. as compared with a mean of 

 138 mm. for the modern skull.
