I. Introductory. 
In a series of papers read before the Cotteswold and other 
Naturalists’ Field Clubs during the last ten years I have given 
the results of an attempt to solve the problems presented by 
the superficial deposits of the Cotteswold-Malvem region in 
their relation to the Glacial Epoch. The fragmentary nature 
of the evidence and the uncertain origin of many of the Drift 
pebbles naturally rendered some of my solutions of the problems 
merely tentative.
