(probably owing to some error,) on a me¬

which have been more recently explored 
and delineated. Hence I infer, that, al- 
I though both Arabasca and Slave Lake are 
within the concave, yet the great lake 
Iiearne discovered, although on or about 
the same parallel, is still further within 
and on the inverted meridians, 
If Parry’s Voyage, or Franklin’s Jour* 
ney, were to be procured in this region, I 
could, perhaps, form my conclusions with 
more certainty. I clamber forward, one 
step upon principle, and the next upon fact 
m search of truth. Respectfully, & c .

any fish which only appear in the Lake perio-
