FOR THE CINCINNATI GAZETTE. 
Gentlemen —1 have lately received, 
from the author, a copy of Doctor New-| 
man’s work mentioned in the paragraph 
below which is extracted from the Na¬ 
tional Intelligencer of the 14th instant, 
I have deposited the book in Mr. Lang- 
don’s Reading Room for public inspec¬ 
tion. I venture whatever reputation I 
may have, for just opinions in philosophy, 
that the views or principles of Doctor 
Newman, as contained in the quoted part 
of the paragraph below, particularly the 
parts which I have taken the liberty of 
marking in italics, are as well founded as 
they are new. 
Respectfully, 
JOHN CLEVES SYMMES.

FROM THE NATIONAL INTELLIGENCER. 
TO THE EDITORS. 
Gentlemen— I request you to publish the 
following extract of a letter from Doctor New¬ 
man, of Hampshire county, Va. It contains a 
condensed view of the new and ingenious doc¬ 
trines advanced by that gentleman, in a work 
which isbefore the public, entitled, “First views 
of the nature and treatment of Hydropic Affec¬ 
tions:” a work, which contains a number of in¬ 
teresting medical facts, and which is entitled to 
much more attention from the profession, than 
it has heretofore received: 
"That no fluid or solid can move unless unequal¬ 
ly pressed*, and then it moves in the line of the dim¬ 
inution of the pressure. A particle of matter, equal¬ 
ly pressed, cannot move. A ball moving on an in¬ 
clined plane moves under the influence of unequal 
pressures The planets move upon the same prin¬ 
ciple. If the sun were stationary in the centre 
of the system, diminutions of pressure could not 
exist, and the planets, consequently, could not 
move. The motion of that body gives motion to 
the planets The diminutions ofpressure formed 
by the heart, gives motion to all the fluids of the 
body. Attractions and repulsions have never 
been understood; because , in nature, they never had 
an existence. We have been deceived by appear, 
auces, and the scholastic ascription of properties 
to matter which matter could not possess .”
