be brought forward. Neither of the rival glacial theories requires 
belief in the annihilation of all living things in our area. On the 
and-ice hypothesis there must have been a now submerged tract 
bordering on the Atlantic, and stretching beyond the present 
south coast of Ireland, which the late Professor Carvill Lewis recog- 
nised as an unglaciated area. A similar elevation to the west of 
our present British islands is believed to have accompanied the 
submergence by which the other school of geologists explain the 
Pleistocene deposits. And it is generally agreed that the south 
and, in part at least, the midland areas of England were free from 
glacial conditions. When we remember how distinctly temperate 
and even sub-tropical forms of life can be found to-day close to 
areas of glaciation, it must be admitted that there is no impossibility 
in the suggestion that the ancestors of the older plants and animals 
which we now see around us witnessed in our territory the coming 
and passing away of the age of ice.
