s of the successive Celtic hordes,
until ultimately we find the latter in possession of a considerable part
of southern Spain, forming by their union with the conquered the
powerful nation of Celt-Iberi. The Iberians were in possession of the
continent before they were dispossessed by the Goidels, and at a later
time by the Brythons. They are recognized by Tacitus in Britain in the
Silures of Wales; and they are still to be seen in the small, dark,
lithe inhabitants of North Wales. The discovery of the characteristic
skulls of both these races in the same family vault in the cave of Gop
near Prestatyn, Flintshire, proves that the two races were mingled
together in Britain as far back as the Bronze Age.

From the present distribution of this non-Aryan race it is obvious that
they were gradually pushed back westward by the advance of tribes coming
from the East, and following those routes which were subsequently taken
by the Low and High Germans.

The exploration of the Grotta dei Colombi, in the island of Palmaria,
overlooking the Gulf of Spezzia, in 1873, proves that the stories
scattered through the classical writers, that the caves on the
Mediterranean shores were inhabited by cannibals, are not altogether
without foundation. In it broken and cut bones of children and young
adults were found along with those of the goat, hog, fox, wolf,
wild-cat, flint flakes, bone implements and shells perforated for
suspension.

_Prehistoric Caves of Bronze and Iron Ages._--The extreme rarity of
articles of bronze in the European caves implies that they were rarely
used by the Bronze folk for habitation or burial. Bronze weapons mingled
with gold ornaments have, however, been discovered in the Heatheryburn
cave near Stanhope, Durham, as well as in those of Kirkhead in Cartmell,
in Thor's cave in Staffordshire, and the Cat Hole in Gower in
Glamorganshire. In the Iberian peninsula the cave of Cesareda, explored
by Signor Delgado, in the valley of the Tagus, contained bronze
articles, associated with broken and cut human bones, as well as those
of domestic animals, rendering it probable that cannibalism was
practised in early times in that region. Busk believes, however, that
the facts are insufficient to support the charge of cannibalism against
the ancient Portuguese.

Caves containing articles of iron, and therefore belonging to that
division of the prehistoric age, are so unimportant that they do not
deserve notice in this pla
