CURIOUS PROPERTY OF HEAy-M,
G. j. Henderson of Edinburgh has =
Gently conducted experiments to end
out the Most economical way Of heaias
public halls, and has decided the hsss'
results were obtained by using an sces
mc.ator or store-room, where the hn,
generated by any means is collectsd
and discharged through one opening
about three or four feet square from H.
floor. The experiment developed IN
fact, Unexpectedly, with what instaa.
taneousness and equality heat is trans
mitted through space independent d
the direction by which it enters, which
was proved by thermometers.
PUTTING AWAY FURs FOR SUMNER
When you are ready to put away fus
and woolens and want to guard agains
the depredations of moths, pack then
securely in paper -four sacks and 10
them up we'll. This is better than cam
phor or snuff scattered among them IN
chests and drawers. Before putting
your muffs away for summer, twis
them by the cords at the ends, 50 tAa
every hair will straighten. Put then
in their boxes and paste a strip Of ps-
per where the lid fits on. A small piece
of paper or linen moisieued with tur.
pentine and put into the wardrobe, Is
also good preventive for moths.
A NEW and very valuable antisptic
has been discovered in Germany. lis
a double salt of borate Of potassium aad
iodium, and is made by dissolving ID
water, equal portions, chloride Of potas
SUM, nitrate of sodium and borsce
acid, filtering and evaporating to dry
ness. 1t costs about 20 cents pound,
and does not give bad taste and proper
ties to food. Butter may be made from
milk kept sweet by it at ordinary tsn
perature for a week. Meat, game, etc.,
dipped in weak solution, remain pure
for long time. A piece OF meat well
rubbed with the salt and laid away two
years ago, is now in perfectly good con
dition. Eggs are dipped in solution;
beer and wine are placed in bottles pre-.
viously rinsed by it, and remain good
fer long periods.
IRON IN THE ATMOsPHERE.-0bservs'
tions on snow collected on mountain
tops and within the Arctic circle far b.
yond the influence of factories ana
smoke, confirm the supposition tns'
minute particles of iron float in the y
mosphere, and in time fall to the earth.
Some physicians believe that these hoas'
ing particles of iron are concerned y
the striking phenomena of the aurora
Gronemann of Gottingen holds thsl
streams of the particles revolve round
the sun, and that when passing %
earth they are attracted to the poles
and thence stretch forth as long MS
ments into space. But as they trsve
with planetary velocity, they becon'
ignited in our atmosphere, and thu
produce the luminous appearances o
aurora. In his recent voyages, Proi
Nordensk jold examined snow far IN ID,
north beyond Spitzbergen, and foune
therein exceedingly small particles o
metallic iron, phosphorus and cobalt
A NEW theory, based chiefly on chem
ical considerations, is propounded q
Prof. Mendelejeff regarding the lorna
ton of petroleum in the interior OF ID
earth. From the fact that in Pennsyli
vania petroleum occurs in the Devon
an and Silurian rocks, it appears y
him highly improbable that the nm'
hydrocarbon should be the result OF 10
decomposition of organic remains, T.
but little organic life could have exlse'
in those ages. His theory, startn!
with Laplace's hypothesis of the lorna
ton of our globe, assumes the e1ls'
ence of great masses OF iron, ana
along with il, of inorganic carbon, y
the inner parts of the earth. The We
ter which, from the more exterior u
gions, penetrates the molten metal,
aecomposed; its oxygen goes to =, I,
ron, whilst its hydrogen unites, unas
,he influence of great heat and pressuis
with the carbon, to form the varlesle
If hydrocarbons which make up peuo
