of philosophising is very commodious, but 
had he reflected that the laws of gravity 
are directly in opposition to the theory ; 
! that water is an assemblage of little parti- 
1 cles, long, flexible, and polished, which 
easily penetrates the pores, and expels 
therefrom the air which causes its light¬ 
ness, and thus serves for the base of other 
elements, he would have learned that his 
philosophy was not the most wise. 
How does Mr. Symmes explain to us, 
by his theory, the phenomenon of the ni¬ 
trous and gross vapours which the vertical 
rays of the sun raises from subterranean 
sources, on regions that are deprived of 
them, or that receive them too obliquely, 
that the etherial matter might agitate the 
water which produces the ice ? 
How does he give us a plausible reason 
to make coincide with his theory, the 
melting of the snow and ice, without the 
equilibrium will be altered, or the means, 
without which, the torrid and temperate 
zones, would be calcined by the burning 
ardour of the sun ? 1 hese reflections are 
simple, but they become the mind, when a

ret. all that can be seen.
