(Sabaerial surfaces much decreased ; as represented by Lyell, ' Antiquity of Man,' fig. 40, p. 287 ) 
». ? Muswell UiU (near London) drift. 
Much uustratified till, formed in preceding stages, eroded and rearranged.— Copford (Essex)

Highest and lowest regions enormously glaciated, the resulting debris (uustratified till) often 
becoming mixed with the Scandina\-ian iceberg-transported blocks of the f Uocene period, es- 
pecialli- in the area of the German Ocean (not in existence at this time) . — Much of the surface- 
features of the British Isles formed. Antrim basaltic plateau in many districts deeply eroded ; 
formation of valleys of the Thames, Severn, Tyne, Tees, etc. 
lighest mountain-regions of British Isles under glaciation.
