FROM CAPT. StMMES. 
I» D. P’s- late strictu^ot j ^ the 
he still contends P ert ‘" aC ‘°S’s vm mes 
new theory of the ear , ^ f/ailey’s 
has published, should nd not 
theory—or otherwise, Kepler , 
! Synnnes’s. D. P. surety can notsugesi 
a doubt, of the originality of 
idea of polar openings (which is ^ far t're 
most important hypothesis o is 
—because, without such openings, ‘ 
ternal formation of the earth could never 
be ascertained by inspection, noi j 
course, be universally admitted y 
world)why then does he forbear ma¬ 
king anv allusion thereto; and why does 
he affect to consider Doctor Halley’s and 
Kepler’s, (and he might also have added 
I Euler’s if not Whiston’s,) ideas of an in¬ 
ternal magnetic ball , or iiucleus, the same 
ds Symraes’s idea of m'any concentric hol¬ 
low spheres* and e.tich sphere with open 
j poles. The two i'ieas, or theories, as they 
stand on record, not only differ from each 
other in the important points above enu¬ 
merated., but differ in most if not all the 
minutiae attendant on eachj particularly 
in that of the mid-plane or volcanic space, 
?*s well as in the nature of the matter of 
the central parts. 
Doctor Halley, as D. V. states, ** considered 
it by no means improbable , that the different 
spheres may be inhabited by living beings ’ 
And the ** concaVe arches, may in several pla 
ces sdilne with auoh a substance as invests the 
tody of the sun”—whereas on the other hand 
I Symmes has declared that the concave (of this 
sphere at least,) is actually habitable; and ob¬ 
tains its light from the same source that we 
do:—and that the lands are rich, end stocked 
with thrifty vegetables and animals, if not men 
If the new theory can be called Kec- 
4 ) ei ’ s °y Halley’s,why do not the world c!l 
it so, instead of styling it the New Theo¬ 
ry ' an <l if it cannot be called Kepler's or 
Halley's Theory of the Earth , it certainly 
! S f £ mmes ’ s > sw as it is a new theory;-! 
, P^ ei ’s and Halley’s theory be called 
- epler s and Halley’s, and Svmtnes 
the °ry be called Symmes
