stances, that a passage leads through some of the Sounds on 
the north side of Hudson’s Bay into the Polar Sea; that in 
inland seas, having but small outlets, there is little or no tide ; 
that in such places, what tide there is, rises highest in the inlet, 
where the sea is narrowest, and becomes less and less consider- 
able, in proportion as the sea enlarges within ; that the highest 
tides, in such situations, are occasioned by winds blowing into 
the inland sea, in the direction of its strait, communicating with 
the main ocean, or in the direction of the course of the tide on 
the exterior coast ; and that the time of high-water is soonest at 
places near the entrance of the inland sea, and progressively later 
in other situations, according to their distance from the strait 
through which the tide flows. These facts he derives from ob- 
servations on the winds and tides in the Baltic, Mediterranean, 
and other inland seas. From the application of these principles, 
Ellis proceeds to shew, that every circumstance with regard to 
the tides in Hudson’s Bay, is different from what would take 
place in an inland sea ; and then concludes, that Hudson’s Bay 
is not such a sea, but has some opening which communicates 
with the Frozen Ocean on the north-west. Just within the en^ 
trance of Hudson’s Strait, at Cary Swan’s Nest, the tide was 
found by Captain Fox to rise but six feet ; whereas on the west 
side of the bay, where, from the great expansion of the waters, 
the tide, according to theory, ought to have been scarcely percep- 
tible, it rises in different places ten, thirteen, and seventeen feet. 
The flood-tide on the west side of Hudson’s Bay flows towards the 
south ; and the time of high-water is soonest the farthest towards 
the north ; both of which circumstances, supposing Hudson’s 
Bay to be an inland sea, with only one entrance from the east, 
should, Ellis conceives, according to the doctrine of tides, have 
been just the contrary. And, lastly, the highest tides on both 
sides of Hudson’s Bay, are produced by north and north-west 
winds ; whereas, were it an inland sea, it is clear, that east or 
south-east winds, blowing directly through the strait, or in the 
direction of the flood-tide without, would produce the highest 
tides. Hence he concludes, that the tide of flood flows into 
Hudson’s Bay, through some other entrance than that called 
Hudson’s Strait ; not from Baffin’s Bay either, because the tid^
