PREHISTORIC TIMES. 15
thousands of years. Again in North Africa and Syria we find in
dry regions wide-spread fluviatile accumulations which are believ-
ved to be indications of rainy seasons, contemporaneous with the
Glacial period of Europe.* If this contemporaneity can be
established, the high estimate of time for the commencement of
the Post-Glacial period in Europe will have to be given up, or at
any rate much curtailed.
As regards the races which inhabited Europe in these early
ages, the evidence furnished by human remains or skulls shows
that they were the direct ancestors of the races now living in the
different parts of Europe. The current classification of the human
races into Aryan, Semetic, Mongolian, &c. is based upon the
linguistic principle; but it is evident that in dealing with ancient
races the archæologist and the geologist cannot adopt this princi-
ple of division, inasmuch as their evidence consists of relics from
which no inference can be drawn as to the language used by the
ancient man. The shape and the size of the skull have, therefore,
been taken as the chief distinguishing marks to classify the
different races of prehistoric times. Thus if the extreme breadth
of a skull is three-fourths, or 75 per cent., of its length or lower, it
is classed as long-headed or dolicho-cephalic, while if the breadth
is higher than 83 per cent. of the length, the skull is said to be
brachy-cephalic or broad-headed; the intermediate class being
styled ortho-cephalic, or sub-dolicho-cephalic, or sub-brachy-
cephalic according as it approaches one or the other of these
types. Now from the examination of the different skulls found in
the Neolithic beds it has been ascertained that Europe in those
early days was inhabited by four different races, and that the existing
European types are directly descended from them. Of these four
races two were dolicho-cephalic, one tall and one short; and two
brachy-cephalic similarly divided. But the Aryan languages are,
