THE RACIAL GEOGRAPHY OF EUROPE.

population of the British Isles to-day is so homogeneous. The aver- 

 age cephalic index of 78 occurs nowhere else so uniformly 

 distributed in Europe, nor does it anywhere else descend to so 

 low . a level, save at the two extremes of the continent in Scan- 

 dinavia and Spain. For purposes of comparison we have repro- 

 duced two maps of these regions herewith. Of Norway we know 

 more in detail than of Sweden, thanks to the indefatigable Dr. 

 Arbo; but the one country is typical of the other. These maps 

 make it clear beyond a shadow of doubt that in these two outlying 

 members of Europe we have to do with relatively homogeneous 

 populations in this respect. Other facts in our possession prove that 

 this uniformity of head form is the concomitant and index of two 

 relatively pure, albeit widely different, ethnic types Mediterranean 

 in Spain, Teutonic in Norway. Purity of descent in each case 

 that is to say, freedom from ethnic intermixture is the direct and 

 inevitable outcome of peninsular isolation. It is now proper to 

 ask and this is the crucial question, to whose elucidation all of our 

 argument thus far has been contributory whether we may make 

 the same assumption of racial purity concerning the British popu-

lations. We have a case of insularity even more pronounced than 

 in Spain or Norway; we have cephalic uniformity. The interest 

 of our problem intensifies at this juncture. If relatively pure, have 

 we to do with the type of the Teuton, or of the Iberian race? We-
