King William’s Land and a comparison with the fossils from 
Frobisher’s bay, shows that that locality bears “somewhat the 
same relation to those of King William’s Land and North Devon, 
which the typical localities of the Utica slate and the Hudson 
River group in New York bear to the more western areas of the 
Mississippi Basin.” “In Frobisher bay we have a group of fos- 
sils unmixed with those of earlier or later date, which mark the 
_ exact horizon of the Utica slate, and the rocks have a lithological 
facies recalling that of the typical localities of this epoch in New 
ork.” “In the north-western area the whole Paleozoic series 
seem to be represented by a nearly unbroken succession of lime-__ 
stones, and the subdivisions merge into each other as in the ` 
central basin of the United States.” “So that Houghton says, 
‘the whole of North Somerset, Boothia Felix, King William’s 
Land and Prince of Wales Land is thus proved to be of Silurian. 
age, although the evidence as to whether it is Upper or Lower 
Silurian is contradictory, as characteristic fossils of both epochs 
are found throughout the whole area?” And the fossils from the 
Bay of Frobisher show that this great Arctic limestone area ex- 
tends greatly to the south-east, and make it comparable in size 
with the central basin of the United States. 
An interesting “note” by Hall on the finding of stones, rocks, 
and sands on the floe ice is given. He believes that these are 
caught up by the ice from the bottom of shallow waters and not — 
deposited upon its surface. . ot 
“ As the spring-tides come on, during their ebb, in many shallow- 
parts of Hudson's bay, sheets of ice rest upon rocks, stones, shells, — 
and weeds. These sheets of ice as they lie, send down showers |
