[Read June 5, 1900.] 
Glacial deposits have already been described in the Hay 
tions of this Society as occurring o n the eastern and southern 
m 
present gulf occupies an eroded hollow or depression in what w. 
formerly an extended area of glacial till. On this assumption it 
seemed highly probable that the southern portions of Yorke's 
Peninsula would be included in the extinct glacial field, This 
very instructive sections of the glacial beds were observed, whilst 
many localities inland furnished confirmatory evidences of the 
previous existence of ice on a large sc 
SOUTHERN Coasr. 
Troubridge Hill.—The first locality visited was Troubridge 
Hill, about ten miles from Edithburg, in a south-west direction, 
vià Honiton. The sea-cliffs near the Hill are composed of cal- 
fies its specific name, as it is mostly aggregated in clusters, 
varying in size up to a foot in diameter. 
The fo llowing is a section of the cliffs as seen at this spot :— 
l. Recent — Travertine limestone i: 18 feet 
ocene-—Fossiliferous (Fibularia gregata) limestone gon 
3. Pre-Tertiary—Glacial till with erratics; thickness yon 
unknown; height exposed above sea level
