.' v JOHN C. SYMMES 
Addresses himself to any who may de- 
ny that his Theory of the Earth is well 
founded, and asks them, to shew to the 
advocates of the Theory, wherein it is 
erroneous; and to offer any other Theory, 
either old or new, which will better 
agree with the facts, phenomena and oc¬ 
currences which have been cited in sup¬ 
port of it. For example, How the prin¬ 
ciple explained in his Memoir, No. II. 
founded on the known or acknowledged 
laws of gravity, may be refuted ? Why 
Saturn is seen surrounded by a concentric 
circle or ring, which if not solid must, at 
least, be liquid? Why the migrating 
quadrupeds & water-fowl about Hudson’s 
Bay, go northwardly in autumn, and re¬ 
turn from the same course in the spring? 
Why certain rivers found by Hearne and. 
Mackenzie (who were doubtless beyond 
the verge without being sensible of it) 
were so remarkably broad and deep as 
they are described to be ?* Why none 
of the Indians Hearne saw,had ever heard 
of any sea to the westward r Why those 
Indians represent the country farther to 
the west or south-west was so warm as 
never to have any frost or snow? Why 
the Esquimaux Indians at Copper-mine 
river, have goods such as the Danes of 
Greenland sell, and none such as the 
British sell at Hudson’s Bay? Why 
Me-lo-no-be, the Indian chief who was 
Hearne’s guide from Hudson’s Bay, point¬ 
ed out Copper-mine river as lying north 
and running an eastwardly course, whilst 
Hearne makes it lie north-west and run 
north ? Why the variation described by 
Capt. Parry, as lately published, corrob- 
erates the meridians long since marked 
on the before mentioned wooden hemi¬ 
sphere f 
i Let any who may deny the Theory to 
be well founded, answer all, or at least 
some, of the many arguments offered in 
support of it, before they undertake to 
pronounce it baseless. And if the author 
and his advocates are to be charged with 
defending an absurd position, let them b e
