"Dhu" (the Black). Rob Roy and Roderick Dhu are familiar illustrations
of this nomenclature. In classical times these types were much less
intermingled than now, and were characteristic of separate races. The
former prevailed almost exclusively amongst the true Britons of the
south and east, and the Gaelic septs of the north, while the latter
was found throughout the west, in Devon, Cornwall, and Wales. The
Silurians, of Glamorgan, are specially noted as examples of this
"black" physique, and a connection has been imagined between them and
the Basques of Iberia, an idea originating with Strabo.

F. 2.--That a good deal of non-Aryan blood was, and is, to be found
in both regions is fairly certain; but any closer correlation must
be held at any rate not proven. For though Strabo asserts that the
Silurians differ not only in looks but in language from the Britons,
while in both resembling the Iberians, it is probable that he derives
his information from Pytheas four centuries earlier. At that date
non-Aryan speech may very possibly still have lingered on in the West,
but there is no trace whatever to be found of anything of the sort in
the nomenclature of the district during or since the Roman occupation.
All is unmitigated Celtic. We may, however, possibly find a
confirmation of Strabo's view in the word _Logris_ applied to Southern
Britain by the Celtic bards of the Arturian cycle. The word is said
to be akin to _Liger_ (Loire), and tradition traced the origin of the
Loegrians to the southern banks of that river, which were undoubtedly
held by Iberian (Basque) peoples at least to the date when Pytheas
visited those parts. The name, indeed, seems to be connected with
that of the Ligurians, a kindred non-Aryan community, surviving, in
historical times, only amongst the Maritime Alps.

F. 3.--It is probable that the status of each clan was continually
