 Barrier glaciers. Beneath them would lie the old delta deposits of perhaps Miocene 

 or Early Pliocene time, except where the weight of the glacier ice, particularly

 seawards. 



In relation to the subject of the probable relief of Antarctica in the neighbour- 

 hood of the horst in relation to the thickness of the covering of inland ice, it may be 

 of interest to compare the sections respectively across Scandinavia, South America 

 in the region of Patagonia, and the Antarctic Horst near Ross Sea. (See Fig. G7.) 



It will be noticed that the section across Patagonia perhaps resembles that of 

 the Antarctic Hor.st in that the present main divide between Chili and the Argen-
