: I contemplate Lc'nomng- the outside of the 
Ule Globe like unto this earth, cut out the 
I '-‘Ceans, continents, rivers, vallies, &c. and if] 
u; contrive any me'thod to counteract the ef- 
*' J ct that our atmosphere will naturally have 
pon it. I have no doubt, from what I have al- 
x*aclv observed, of the effects of motion, that 
he rivers and vallies may be filled with water 
rom the inside, 11)9 ocean filled, the regular 
ceauic currents formed, the water flowing from 
ue inside to the out through the perforations, 
rorn tlie outside to the inside through poles, 
■>ul the whole phenomena explained in a satis¬ 
factory manner, so that the whole process may 
)c se en in miniature with the eye; the polar a{- 
: faction of the needle explained and the varia¬ 
tion of it accounted for. 
1 find by placing the north end of the globe hi 
a dark place, and having a bright light placed in 
dm position that the sun bears to the earth in 
a south latitude, the rays of light are thrown in 
at the south pole, and reflected at right angles, 
•uid pass out at the north pole in a manner per¬ 
fectly r. -Iculated to explain the aurora borealis, 
and show it in a most beautiful manner; and 
shows that the inside or hollow of the earth, may ' 
be as well or better lighted and warmed by the 
sun than the outside. From these experiments 
l am fully convinced of Symmes’s theorv, &, that 
the earth would be incomplete without the hol¬ 
low. 1 am, with much respect, 
Your most obedient servant,
