The author is now able to show the oca^on 
of the true verge with confidence, ile at hi 
presumed the verge to exist near where he, on 
this map, locates the apparent verge; but he 
has subsequently found (what is probab.y owing 
to refraction and to the verge being all a wa.er 
level and the turn gradual) that the existence qt 
the verge is unknown to its inhabitants, and that 
it is located within the civilized regions of Eu¬ 
rope, and considerably to the south of some set¬ 
tlements of white people in America—and many 
hundred miles this side of the appahext verge; 
the concave space between the two. being bent 
eut and elevated to an apparent continuous con¬ 
vexity, by means of aw extraordinary refraction, 
and gradually falling off inwardly every where 
beyond the apparent"^erge,—preserving, how¬ 
ever, throughout the concave, an apparent con-. 
vex surface : all of which, is proveable by many 
directly applicable and excellent tests, both ani¬ 
mate and inanimate.
