the arc that lies between the lambda and inion. Thus the arc from 

 lambda to inion is distinctly less developed in the short cist skulls. 



In six male skulls the proportion of the base line to the sagittal 

 arc is as 1 to 27(5, and in two female skulls as 1 to 271. Turner 

 gives the average relation for a series of seventeen modern Scottish 

 male skulls as 1 to 2'8. 



In the cist skulls there is thus a larger proportion of base line to 

 sagittal arc. 



Tniiinrcrtti' Ciri-Mmfcri'in-c. The average for six male skulls is 

 447'6 mm., and for two female 424 mm. The corresponding figures 

 for modern Scottish skulls are 434 mm. and 409'6 mm. respectively. 



Foramen M<i</iniiii. The foramen magnum is of an average si/r. 

 The occipital condyles have their articular surfaces Hatter and simpler 

 than usual. The anterior ends of the condyles are far apart, so that 

 the long axes of the condyles are less convergent. 



Gnut lih- ///I/IT. The average for five male skulls is 92'6, while 

 one female skull has an index of 96 '9. The index for the males is 

 distinctly less than that of the average modern Scottish skull. None 

 of the cist skulls shows any trace of prognathism. 



Coinpli'ti' I'^idul ImJiT. All the skulls, with the lower jaw intact, 

 have a short nasio-mental length, while the inter/ygomatic breadth is 

 great. The complete facial index is thus very low, the mean for five 

 males being 81 - o as compared with an index of 92'3 for modern 

 Scottish male skulls. 



\*l Index. The nasal aperture as regards height is rather 

 under the average, while the width is relatively large ; in four of 

 the skulls the height is less than twice the length. The mean nasal 

 index is just 50. This index is much larger than that for modern 

 Scottish skulls, which have a mean index of 42 - 5. 



()rl>iil Index. The width of the orbit was measured from the 

 dacryon to the most distant point on the edge of the outer border 

 of the orbit. The index in five males averages 76'2, and in one 

 female skull it is 82'5. The orbits in all are distinctly microseme, 

 much more so than those of modern Scottish skulls, which have a 

 mean index of 86 - 4.
