ROUGH STONE MONUMENTS 



with a race which made enormous journeys, and 

 thus became contaminated by the various other 

 races with which it came in contact. It may even 

 have been a mixed race to start with. Thus even 

 if we found skulls of very different types in the 

 dolmens this would not in the least disprove the 

 idea that dolmen building was introduced into 

 various countries by one and the same race. It 

 would be simply a case of the common anthropo- 

 logical fact that a race immigrating into an already 

 inhabited country becomes to some extent modi- 

 fied by intermarriage with the earlier inhabitants. 

 The measurements given in the last chapter would 

 seem to show that despite local variation there 

 is an underlying homogeneity in the skulls of the 

 megalithic people. 



It thus seems that the most probable theory 

 of the origin of the megalithic monuments is that 

 this style of building was brought to the various 

 countries in which we find it by a single race in an 

 immense migration or series of migrations. It is 

 significant that this theory has been accepted by 

 Dr. Duncan Mackenzie, who is perhaps the first 

 authority on the megalithic structures of the 

 Mediterranean basin. 



One question still remains to be discussed. From 

 what direction did megalithic architecture come, 

 and what was its original home ? This is clearly 

 a point which is not altogether dependent on the
