Artificial Gold.

In this mornings Tribune you solicit from some
of your correspondents an answer to an in,erroga
tory respec,ngthe method ofprecuring the greatest
intensity of artificial cold. and having, in
ton with one or two other gentlemen, performed
| these experiments on somewhat extended scale,
take pleasure in replying TO it.
The greatest degree of cold is obtained by the
liquefaction and qualification of cARBoN1c ACID
Gas, which is done by subjecting it to a pressure
of &c atmospheres, which, at Is lbs to the square
inch, at tie common temperature, gives a power
OF about $50 lbs 10 the square inch. The expert
ment is performed commonly on small scale, by
taking very strong glass tube and Theoretically
closing one end; into the other is poured snail
quantity of sulphurc acid, and small platinum plat
torn is then dropped IN. Super-carbonate of soda
CSo.+o) ~ (C+2O)l is then placed on the plat
form, and the tube closed, and Inverted so as to
bring the acid in contact with the super-carb soda
By the action of the sulphuric acid the excess of
carbonic acid in the soda is liberated, and having
no opportunity to escape, is condensed.
1t is performed on large scale with large iron
condenser in which the process is the same, but
which affords the opportunity OF refrigeration, by
means of strong tube, sufficient 10 withstand the
great pressure; and the gas, when liberated frosl
the soda, is discharged through it into a metallic
cup with a number of small holes punctured in the
cover. On det2ching the cup, and opening it, it is
found partly filed with somewhat compact and
faultlessly white snots which will retain its form
for time but will entirely cvaporate on expos
ure to the atmos pherc. | do not recolect the
specific gravity, and do feel certain that it has
been ascertained. The degree of cold is SO great
that mercury (quicksilver) placed upon it, is mme-
diatcly frozen, and becomes as maable as com
mon lead.) The gas in escaping and regaining
the invisible form, consumes so much heat, which
has been expelled from it by condensation, that it
produces an intense cold-equal to 600 of Fahrcn-
heit. The degree of cold is measured By a spirit
thermometer, as u mercurial instrument would not
answer the purpose-mercury freezing at $50 Of
teresting discovery of solidifying the gas was
originated by NJ. THllLoRlER, Of Paris about
i've years ago, and a full account Of the process
may be found in the Journal of the Franklin Inst-
tute of Philadelphia, at the close of 1885, and also
in Siliimans American Journal of Science publish.
ed about the same time.
The great FORCE of this gas, which, as above
stated, is $50 lbs the square inch, has been APP
Piled but with limited success, as mechanical
agent in propeing machinery, but the difficulties
attending its ac,iona are so great that it will never
be much, fiat all, employed for this purpose.
Artificial cold may also be produced, though
aot with much intensity, by several other inter-
esting methods
Four parts of strong nitrous acid poured on
ssven pats Of snow, will give atemperature Of
800 $500 deg. below Zero.)
EQUAL parts of snow and common salt, give
of-50".
Crystalline chloride Of calcium mixed with two
,hirds ,.y of cnow will nroduce cold suffi.
cient To freeze mercury.
Sulphurous acid, under pressure of two atmos-
pheres, or q cold of 100, is converted into liquid
The method ofproducing this degree of cold is that
mentioned above, mixing ice or snow and salt
This method of obtaining cold is performed every
day ulmostby ice-cream manufacturers. w. O. b.
IMPORTANT DECISION IN BANKRUPTcY-LAED-
LORDS AND TEEANTs.-A decision of great inn
portance was made on Wednesday, August II, in
the u. S. District Court, Hon. Tuos. IRWIN on
the Bench, sitting in Bankruptcy; it involves the
right Of landlord to distrain property for rent,
after it has been returned as that Of the bankrupt
by whom the rent is due. The circumstances Of
the case are as follow:
Thomas Hudson rented farm from VIM Ross,
Jr for two years from April, 1S4l, rent payable
yearly. The years rent, which became due and
payable on the 1st of April last, not.paid, and
on the 21st of June, 1912, Hudson presented his
petition in Bankruptcy, and the Court fixed the
22d of August for the hearing. On the 10Th of
August, Ross, (he landord,) distrained the
property of the bankrupt on the premises, for the
wears rent which was due the LIST of last April;
this property was Included in HudsoRs schedule
annexed TO his Petition. The Bankrupt applied
to the Hon Thos. Irwin, and obtained rule to
show cause why an injunction should not issue, 20
restrain the landlord from proceeding under his dis
tress and why he should not restore the property
diStrnined.
On the 18th of August, the case was argued by
Hon. F. r. Skunk, late Secretary OF the Common
wealth, for the Rule, and by Hon. II. II. Van
Amringo, formerly Recorder of our city, for the
Landlord On the 18th, the Rule was dismissed,
the Court being of opinion that the right of the
landlord to disirain the property on the premises
and to sell, was not impaired under the provisions
of the Bankrupt Law.
We have not learned whether the decision rea-
tive to tie right Of the landlord to distrain ex-
tends 10 rent accruing after the filing OF his Pc
ti,on, or whether for such rent, property returned
in the schedule can be exposed to sale.
We sex. it stated that Jud ge Pennybacker, OF the
United States Court for the Western District OF ViI-
ginia has decided that {" atter the filing of the pc
tiiion III Bankruptcy and the order Of publication,
the petitioner is exempt from ca. sa and that no
execution can be levied upon his effects, nor can
landlords carrant of attachment This is con-
trary TO Judge lrwin's decision.
