As Jupiter’s ex t e "° r o ^| a |.J^ e g^ a round

near the plane of his eguator-a,> infer¬ 
ence is afforded, that the reason why re¬ 
fraction does not appear to operate on 
Juniter as on Mars and the earth, is, that 
the rapidity of Jupiter’s rotation throws 
mos t of his atmosphere from his po es to¬ 
wards his equator: such must also be the 
case with Saturn. , 
The Italians, in Galileo’s time, used a 
telescope which magnified but twelve 
times; the English now use one which 
magnifies more than sixty times; and why, 
I ask, should not the United States (by 
having an able Astronomer perpetually 
under pay) try to make a still further im¬ 
provement in the telescope ? Who will 
undertake to say a further improvement 
is impracticable ? 
Why, may I here ask, do not the United 
States send out naval expeditions to make 
discoveries in the yet unexplored re¬ 
gions of the earth, as several nations 
of Europe have done? (in which unex¬ 
plored regions, an abundance of fish and 
quadrupeds do, it is generally admitted , 
exist, and where, for aught the community 
know, men, and all kinds of animals and 
plants abound, and where the climate is 
temperate and the region fertile: surely 
die Americans have not heretofore obtain¬ 
ed greater credit for enterprize } discov -
