. Will not the increase of gravity towards and with, 
in the verge, if such as I describe, account for the 
great condensation of the fluids of the thermometer 
when high north; and, account for the facility with 
which water and other fluids crystalize there? If it 
will not, how was it that Parry’s crew endured the 
open air when the fluid in the thermometer was low 
in the extreme, with so little inconvenience as they 
did f 
' here is, I conceive, but little to be apprehended 
from intemperate weather within the concave. Hearne 
t uvelled in mid-winter without dwelling much on 
the cold, except while in the neighborhood of Hud¬ 
son’s Bay, where he started from ; and even there, it 
cannot be great, as he started on his journey in win¬ 
ter. Col. Dixon, of the Hudson Bay Company,when 
just from the Bay this year, informed me that lie 
could travel there against the N. W. wind when the 
quicksilver was solid, with as little inconvenience as 
he experiences in travelling here in ordinary cold 
winter weather. 
he more minute data on which the explanations 
and conjectures I other are founded, I design to lay 
before the public as soon as it can be suitably done'; 
or, as much thereof as will be necessary to satisfy the 
thinking world of the general truth of the principles 
I profess. 
If my averring that the tangent with which a stone 
leaves a long sling makes a less sudden angle with the 
circle described by the stone before let "fly, than is 
the case with a short sling, goes to prove that the 
centrifugal force becomes less removed from a hori¬ 
zontal direction, as matter is removed farther from 
the centre: and if my saying gravity is an impelling 
rather than a pulling power (owing, perhaps, to the 
circumstance of all space being replete with an elas¬ 
tic fluid) and that this impelling or repulsing power 
acts more forcibly on any given space of the surface 
of a large sphere than on that of a small one—I say, 
if my offering these two suggestions (whether now or 
at any future time) to account for the circumstance of 
any matter diverging from the centre stopping at 
some finite distance, does not satisfy the reader, it 
may be passed over as nugatory, without detriment 
to the main question: for, the surface we tread upon 
proves that the matter of the Earth has stopped: and 
any thing we put in rotation shows the .centrifugal 
force. And the same thing will apply to many oth¬ 
er of my arguments. For example, if .I err'in tel¬ 
ling how the rays of the sun fall, by this or that law, 
on the concave within, it matters not, provided I 
prove they really do fall, &c. &c. 
I am of course subject to error as well as other 
men—Newton left many things unaccounted for,and 
some that he attempted (the tides for example) were 
but imperfectly accounted for; yet, we do not there¬ 
fore deny those things be established on a stable base; 
1 expect no one to receive my conclusions for more 
than he finds them to be worth after weighing them 
in the balance ot reason. I must, like other theo¬ 
rists, be allowed the privilege of drawing.conclusions 
and advancing them, as I have done throughout the 
piece—without always stating the process by which 
they were deduced; otherwise I cannot be as briel'iu 
my explanations, as circumstances may require.
