Thanks WBC for his account of glacial action in Australia. A mundane cooler period would throw a flood of light on geographical distribution. Has sketched a large MS on subject but does not know whether he will live to publish it.
Questions WBC on striated granite boulders.
Asks him to make a botanical experiment on insect fertilisation.
