aluminium and tin are now gilded and
silvered so completely that the layer can
not be disturbed by the hardest hurnisher.
The weather has been so warm in Ber-
lin that one of the chestnut trees in the Liza
coin promenade is decked with second
crop Of blossoms-a thing hitherto unheard
of in the annals of the city.
The torpedo has been utilized for peace
purposes. In the oil regions, when well
yields nothing, they sometime explode a
torpedo at it's bottom. The effect is FREE
quently to start copious supplies of oil from
prolific strata lying adjacent to the we'll.
"A Lyons, France, journal states that a
new breast plate, made of cork, from an
inch and half to three inches thick, and
covered with metal on one side and uniform
cloth on the other, has been exhibited in
that city. 1t is very light, and is said to be
a good oefense against either sabre, bayonet
or bullet.
A solution of gold was, in the early
days of chemistry, deemed impossible. 1t
was first found that limited proportions are
soluble in sulphuric and nitric acids togeth-
er, and it is now ascertained that it is easily
soluble in the ethereal solutions Of the per-
chlorides and perbromides. Hence, if gas
eous hydriodic acid is put into ether CON
tanning leaf gold, it will be dissolved and
the acid decomposed.
MIR. Babarin, of New Orleans, has in
vented and patented acontfivanee for stimuli
taneously lighting all the lamps of theatre,
hotel or even of an entire city. A machine,
like an alarm clock, can be set to any hour,
at headquarters, and when the appointed
time comes, all gas burners connected with
it are instsntaneously set ablaze. The in
vention is to be publicly exhibited and
tested in New Orleans in a few days.
"A new species Of loadstone. has Just
been discovered. 1t appears that iron and
steel shavings, and particularly the long
spiral ones produced in twisting vices, pos
sess magnetic properties in the highest de-
gree This magnetic property is of du-
rable nature, and Mons. Gruss, who made
the experiments with the above, states that
the south pole will always be placed at the
extremity first touched by the instrument.
"A German forest keeper, eighty-two
years old, not wishing to carry to the grave
with him an important secret, has published
in the Leipsic Journal, a recipe he used for
fifty years, and which, he says, has saved
eeveral men and a great number of animals
from horrible death by hydrophobia. The
bite must be bathed as soon as possible
with warm vinegar and water, and, when
this has dried, a few drops Of muriatic acid
poured upon the wound will destroy the poi
son Of the saliva, and relieve the patient
from all present or future danger.
The modes of CESSATION among fishes is
astonishingly various. Some are viparous.
In several species the eggs are carried
about the outside of the body Of the pa
rents. In some the eggs are attached
to the forward fms and uader side of
the head. Some are carried and Matched
in pouch precisely analogous to that of
kangaroo. In Guinea, curing the breeding
season, catfish are offered for sale with their
mouths literally crammed with eggs and
young in different stages Of growth and de-
velopment. Agassiz has recently observed
in Brazil that many species of CHRONICLES
carry their eggs at the back of their mouth,
and that some species Of the loricarias car
ry their eggs attached to The broad mem
brane which surrounds the mouth.
