TOR THE NATIONAL REPUBLICAN. 
Th e first Chapter of a series of Questions . 
Messrs. Editors— 
I ask all who doubt the correctness 
of my Theory of the earth, the follow¬ 
ing questions : 
Why did Captain Ross, when in 
Baffin’s Bay, see the Aurora Borealis 
very often in the south, even down to 
the horizon, and very seldom to the 
north ?—unless it be that he was with¬ 
in the concave, described in my map, 
published in September last: in which 
case the verge behind him, where the 
light appeared, would be to the south. 
Why does the Barometer fluctuate 
but very little high porch, (as Captain 
Ross states) whilst in lower latitudes, 
—viz. south of the verge drawn on my 
map,—it fluctuates greatly: vascilla- 
ting less and less as it advances to¬ 
wards the equator, and scarcely vary¬ 
ing at all within the tropics—why 
does it thus correspond with my prin¬ 
ciples, unless my theory and map be 
correct ? 
I 
Why are the tides at their greatest 
general heighth, on the east coast of 
north America, between New-England 
and the north of Labrador; and on the 
N. W. coast, between Columbia river 
and Bherings scrait; and thence be¬ 
come lower, as one progresses north, 
until they entirely cease beyond Bhe¬ 
rings strait, and almost cease beyond 
Davis’s straits; and decline southward 
in like manner, until they cease at the 
equator?—How happens this, unless 
my conclusions are well founded, as 
explained in the map?
