The Scottish palatal index shows a remarkably small standard deviation compared 

 with that shown by the English and Naquada crania. 



As regards the maxillo- facial index in the male, the Bavarian shows the least 

 \ a liability, then the Naquada, while the English and Scottish are appreciably 

 more variable. In the female the Bavarian is again the least variable ; follow- 

 ing this comes the Naquada; then the Scottish, while the English female is the 

 most variable. 



We have still to examine the orbital and nasal indices, and the following table 

 contains all the figures available : —

In the Scottish series the orbital index was not calculated for both orbits, as 

 there seemed to be so little difference between the mean values of the respective 

 lengths and breadths. The orbital index in the above table is obtained from the 

 right orbit. 



Examining the above table, we observe that the English crania are least variable 

 in both sexes for the orbital index.- In the male the Bavarian is highest in variability, 

 the Scottish distinctly less variable, and the Naquada less than the Scottish. In the 

 female sex we find the Naquada next to the English in variability of orbital index, 

 while the Scottish and Bavarian are distinctly more variable than the latter and show 

 an equal degree of variability. The variability for orbital index is practically equal 

 for the male and the female in the Scottish series. 



In respect of the nasal index, in the male sex the Naquada shows least, the 

 Scottish most, variability, while the English series is just a slight degree less variable 

 than the Scottish. In the female the English is the least variable, the Scottish 

 comes next, and the Naquada is the most variable. The variability of the nasal 

 index is greater in the male than in the female in both Scottish and English series, 

 while the reverse is the case in the Bavarian and Naquada groups. In this Scottish 

 series, as in Turner's, the English, and Naquada series, the nasal index, as measured 

 by the coefficient of variation, is much more variable than the orbital index, although, 

 as M acdonnell points out, Turner says that the latter "shows a great range of 

 variation in the same race, and that it possesses only a secondary value as a race
