SEC0Nb LECTURE BY DIR. DOREMUS.
DR.. Doremus delivered the second lecture Of hi
course upon the History of Creation, at the New
York Medical College Thirteenth street last sning
TIE theatre of the college was well filed. The lee
trer proceeded to eliminate his theory OF the crea
ton, which is founded upon well known chemical
and philosophical facts. His subject was the pro-
bable manner in which light aud heat were first
evolved. He proceeded to give an explanation Of
the various natural gases, and to show that they I'll
entered into the composition Of atmospheric air. By
the expansion and compression of air heat was pro-
duced and this illustrated by actual experiment
piston tipped with inaammsAe substance was
introduced into a cylinder, and by compression OF
the air in the cylinder heat was preducedthe sub
stance was ignited. This was the discovery of q
French soldier, made when experiments were
going on to find some subsnnce to take the
place c2 nitre in the manufacture of gunpowder.
None Of the gases he said show to greater extent
this property-the evolving OF gh. and heat-better
then oxygen, which gas enters into the production
Of everything on the earth or underneath it. The
crust Of the earth in oxydsed mass The lecturer
alluded to the invention of the oxygen bio w.pipe,
and stated that experiments with it were sometimes
dangerous, but that he had arranged an apparatus
which would be sufficient for illustration without
any danger. He introduced powdered antimony
Into jar filled VITA oxygen, when heat and light
were emitted. Metals poured into the atmosphere
in molten state would at once take fire. II we in
troduce 0 coal into jar of oxygen, it becomes q
light at once: illustrated by very successful ex-
periment] Wires tipped with sulphur, introduced
into oxygen give out light [Also illastrated] II is
known chemical fact that material bodies con.
fined with oxygen emit heat In proportion
to the amount of oxygen contained in themA
One pound Of hydrogen united with the Same amount
OF oxygen would raise 232 lbs. Of water to 2l2 Fahr
duces great heat but little light Dr. Hare of Phi
ladelphia, demonstrated that if equal amount OF
these gases we're allowed to escape from one Jet tls
heat would be greater than ever was known 1t ia
singular that if take these gases in the same pro-
portions as they found in water the heat evolved
is the greatest. Platina iron other metals intro
duced into these gases, are not only fused but burned
up. II we take this fact along with the fact that
these proportions go to make up the ocean, the ice,
ihe snow, we may have some idea OF the immense
amount used when these gases irst came together!
patna was first fused by the union OF these gases
they unite to form water DR. Hare, OF Philadelphia
Iosed 32 ounces at one experiment. The lecturer
here experimented upon var metals to show tina
power OF oxygen and hydrogen gases when united.
when intense heat and light were emitted; solid
substances, such as mica and megnesa were
introduced, and q light equal to that discovered
by Lieutenant DruMmond was produced. The ex-
perments were very successful, and the result was
very beautiful. These metals may be evolved back
into liquid and gaseous state. The lecturer said
that he had experimental sufficiently to show that
the vital principle OF the earth and all therein was
oxygen gas-that the whole world was mass Of
oXy ydiZed matter. The combination of tie gases
produces heat and light and the reverse of this pro-
duce the reverse result. II water be oours upon
sulphuious acid at certain temperature the water
will CONCEAL we have sometimes produced snow.
We claim that we have elucdated tn fact that the
earth was once fluid-once gaseous. We do net
claim this as new discovery. La Place and Her.
sche came to the slusion, by the discovery
OF light masses in the heivens-o or nebule-these
passed into myrisds of little suns, and then formed
anetary systems with their satalites. The condi.
tion Of the earth was probably siuilar-like tnem
passed from the fluid to the gaseous state and then
to The sold. AS far the planetary system goes it
has been stated that tnis theory falls to the ground
as the nebulG sometimes resolve and dispense;
but that bas no effect on our theory, which has
different oUl datjon. We have reason to say that
the earth wss originally, chemically speaking
fluid, and on this hypothesis all the plnasts must
have been liquid gas. The elements combined and
made The earth itch was originally without form
and void. Light was evolved from existing ele-
ents, not created. II was evolved by the comprts-
sion OF The gases The command ssexpressed in Gem
isis, is - Let there be light and there was light"
The lecturer then proceeded to his experiment with
sulphurous acid aud water. A vessel was heated to
a red heat, the acid then poured in, water WAS
added, and by dexterous turn Of the vessel snow
fake was thrown out. This experiment concluded
the lecture, which was very Interesting, but which
can hardly be understood without actually seeing
