of man. A yet greater elevation would convert the Bay ot 
Bengal into dry land, join the Andamans to India, the Laccadive 
and Maldive islands to Arabia, converting the Arabian sea into a 
broad expanse of nearly level ground.” At the same time a 
great geological barrier would be erected against the northern 
movement of this type. “Thus we have an ‘area to no small 
extent demonstrably cut off from the northern regions of Asia 
and Europe, in which alone traces of the Aithochroic group are 
to be met with, and the A:thochroic peoples were originally the 
sole occupiers of this area.” Mr. Dallas relies largely upon facts 
developments, one in Africa, the other in the Philippines and 
Andamans, almost pure, still exist. In the other areas the stock 
is much mixed. 
Roughly speaking, the Leucochroic group occupies the whole 
of Europe with the exception of a part of the northern portion, 
and parts of Hungary and Russia. Eastward, members of this 
group exist in the Caucasus, Armenia, Persia, Georgia, Circassia, ; 
Afghanistan, Kashmir,and Hindustan, Kattiwarand Rajputana,and A 
include the Siah Posh Kafirs of the Indian Caucasus, and remnants 
in China, Tartary, Japan, Kurile island and Kamtshatka. Indeed, 
Mr. Dallas looks for the origin of this type in the heart of what 
is now the Mongol area, the plateau of Central Asia, believing 
that they extended along the eastern coast of Asia from Kamt- 
Shatka on the north to the limits of the Æthochroi on the south, 
rom this central region the Leucochroic race passed westward 
by the great depression, the Zungarian strait, to overrun first 
Western Asia, and eventually the whole of Europe, branches - |

of this stock. o
