that ice does not sink into all the hollows, but frequently 
bridges over large cavities; and these hollows would be just 
of such a class as to escape contact with the moving mass 
above ; so that the successive deposits would be preserved 
from time to time, as the ice passed away and returned. 
The following diagram will illustrate the above descrip- 
tion, showing the geological structure of the district and the 
mode of occurrence of the hematite iron ores, and also of the 
ice covering, by which I suppose the superficial deposits to 
have been formed. 
SECTION NEAR DALTON-IN-FURNESS. 
a. Silurian (Coniston Grits and Flags). 
b. Carboniferous (Limestone, with Hematite Iron Ore in veins and “pockets”). 
c. Drift Deposits (Hematite Iron Ore, with Boulder Clay, Wood, and cUbris of older 
rocks). 
d. Supposed Glacier (by which the deposits (c) have been formed). 
“The Results of the Settle Cave Exploration,” by W. 
Boyd Dawkins, M.A., F.R.S. 
Since the results of the exploration of the Settle Caves 
were brought before the British Association at Liverpool, 
in 1870, considerable progress has been made in the further 
investigation of the remarkable contents of the A ictoria
