Further anthropological studies may simplify the problem somewhat, but the author is now inclined to believe that the above-mentioned third brachycephalic type, the “Old Black Breed,” represents the survivors of the earliest waves of the round-head invasion—in Britain antedating the arrival of the Neolithic Mediterraneans, while the first type mentioned above represents the descendants of the last great Alpine expansion. This type in southern Germany has been so thoroughly Nordicized in pigmentation that these blond South Germans are sometimes discussed as though they were a distinct Alpine subspecies. The type is scantily represented in England, and when found may be partly attributed to ecclesiastics and other retainers brought over by the Normans. The second of the above types, the Armenoids, are virtually absent from Europe, and seem to be characteristic of eastern Anatolia and the immediately adjacent regions. The author regards the fourth, Borreby or Beaker Maker type of tall, round heads as distinct from the three preceding types. The distribution of their remains would indicate they entered Britain from the northeast. We have no clew as to their origin. A similar type is found in the so-called Dinaric race of Deniker (which Fleure and James mention in connection with the third type but hesitate to class with it), which extends from the Tyrol along the mountainous east coast of the Adriatic into Albania. Further study of the Tripolje culture (see note to p. 143 : 15) and the mixture of population north of the Carpathians, where the early Nordics and early Alpines came in contact, may throw light on this question, as well as upon the problem of the acquisition of Aryan languages by the Alpines. All these four round skulled types seem to have been of West Asiatic origin, but their relationship to each other and to the true Mongols of central Asia is as yet undetermined. One thing is certain, that the Alpine Slavs north and east of the Carpathians, and, to a less degree, the inhabitants of Hungary and Bulgaria, have in their midst a very considerable Mongoloid element, which has entered Europe since the beginning of our era. 134 : 12 _seq._ For further characters of the Alpines see Ripley, pp. 123–128, 416 _seq._, and p. 139 of this book. 135 : 1.
