THE AIR RENDERED VISIBLE.

At a late sitting of the French Academy OF
Sciences, a very remarkable paper was read
1t was presented by we'll known engineer, NJ.
Andraad, who has made many public expert
ments on compressed air as substitute for
steam on railways. 1t is entitled "Eroscopic.
or the Visibility of the Molecules of the Air"
Some of the deductions made, in medical
point of view, are in the hig hest degree curl
Gus:
NJ. Andraud proves that, by very simple
contrivance, the air is rendered visible. By
taking piece fcard, colored black. and pier.
cling it with fine needle, this interesting fact
is established. If we look through this hole
at the sky, on fine day, or at a strong lamp,
having ground glass, we see a multitude of
little transparent lobes moving in the midst of
confused nebulosities. These little globes,
some of which are more transparent than 9th
ers, are molecules of air. Some of them are
surrounded with kind of halo. These latter
says NJ. Andraud, are the elements ofoxygen,
others were elements of azote. After continu-
ing the observation for some time, we shall see
small points detach themselves and disappear
10 falling; these, says NJ. Andraud, are atoms
of carbon. This phenomenon of vision, il is
essential to remark, passes within the eye it.
SELF the molecules of the air which are OBJ
served, are those which float in the liquid,
which occupies the anterior part of that organ.
According to the author of this paper, the dis
coyery is not interesting merely as phenom
enon, but may be applied to important purpo-
ses in medicine. He says: "The physician
will one day make use Of the aros co .'ie as an
important means of diagnosis. Vertigo, and
giddiness, which are the forerunners of apo
plexy, will be announced by perturbation In
the molecules. Fever always exists when the
molecules under the action of magnetic cur
rent circulate on vertical ground-sometimes
in one sense, and sometimes in another; and
when thislmovement of grayiion becomes more
precipitate, the patient experiences the singu-
lar sensation OF turning, as II were, upon
wheel Of Ixion.
