dam, the general figure of proportion, which has been found, reappears 

 again. 



Thus far 1 have left one province out of consideration, Zeeland. 

 There is no denying that this province takes up a place somewhat 

 separated from the others, since here the number of redhaired persons 

 falls suddenly to 1.8°/ . This contrast with the other provinces is too 

 great not to see here the influence of a definite cause. Yet this decrease 

 in redhairiness in Zeeland, as will be proved higher up, cannot be 

 attributed to a rise in the number of brunettes, which really occurs 

 here, for N. Brabant, which is no less brunette than Zeeland, does 

 not show this decrease. 1 will not enter into the cause of this decrease, 

 I only wish to point out that already repeatedly both by Belgian 

 and Dutch investigators attention has been drawn to the fact that 

 from an anthropological point of view our Zeeland population takes 

 up quite a peculiar place among the inhabitants of our country. It 

 seems to me that this opinion is corroborated by the proportion 

 found for the redhaired persons. 



This much concerning the extension of redhaired persons in our 

 country in general. The general conclusion to which we come, may be 

 expressed thus, that with the exception of Zeeland this extension is a 

 verv regular one all through the country. This fact was really contrary 

 to ray expectation, as I myself, when beginning to work up my 

 data, held the general opinion that there was a closer relationship 

 between redhairiness and blondness. So I expected that, where in 

 our country the blonde type varies so strongly, the influence of this 

 would also come forth in the variation of redhairiness. Let us now, 

 in order to prove the independence of the two phenomena, pay some 

 more attention to Table I. For through this table we also get an 

 insight into the decrease of the blonde and the increase of the brunette 

 race, in a direction from North to South. As I said before, I dis- 

 tinguished on the schedules sent round four colours of hair and 

 four of the eyes, making together 16 combinations. Of these combi- 

 nations there are two which are really characteristical for the race, 

 namely the combination blonde hair and blue eyes for the blonde 

 race and the combination black hair and brown eyes for the brunette 

 race. The other '14 combinations may be considered as mixed forms 

 between the two races. Now, in order to keep the foundation of un- 

 reasoning as pure as possible, I have inserted in Table I only these 

 two combinations to mutually compare them. 



In the third column we find the number and percentage of blond- 

 haired blue-eyed individuals in the different provinces. Now it appears 

 that the number of pure blondes decreases very regularly from North
