THE LARGEST LUMP OF GOLD.
We believe the larges. lump Of gold ever
found, to be that obtained in 1S43, in the
mines south of MASK, and now at ST. Pc
tersburg, the weight of which is no less
than seventy-eight pounds avoirdupois-ils

ALL THE UNIVERSE IN MOTION.
If, for moment, we imagine the acute
mes of our senses preternaturally heightened
to the extreme limits oftelescopic vision, and
bring together events separated by wide in
lervals of time, the apparent repose which
reigns in space will suddenly vanish, count
less stars will be seen moving in groups in
various directions; nebule wandering, con-
densing, are dissoIving, like cosmical clouds;
the milky way breaking up in parts, and its
veil rent asunder. IN every part of the &C.
lestial vault, we should recognize the domin-
ion of progressive movement, as on the sur
face Of The earth, where vegetation is con-
slanlly putting forth its leaves and buds.

REMARKABLE ACCUMULATION OF ICE.
When Captain Parry's ships, Hec7a and
Griper were on their Arctic voyage, the
month of March sci in mildly, Cat their re-

ice, which for some time had line, the ships

necessary to scrape off this coating of ice.

ANTIQUITY OF MAN ON THE EARTH.
M. Paul Jervais has lately discovered in
the upper tertiary stratum of Montpelier
species Of fossil ape, probably belonging to
the .uacaque genus. On comparing this
discovery with that of NJ. Lartet, in the Gers,
and those made in the environs Of London.
it appears that fossil apes have been discov-
cred in the three principal tertiary strata Of
western Europe that is to say, in every
part of the level sedimenlary earlhs in which
the bones of mammalia abound. Ifman had
existed at the period when these strata were
deposited, the non-discovery hitherto of the
slightest trace Of human skeletons. or re-
mains attesting human industry, would be
very astounding. The discovery of these
fossil apes is, therefore, an additional indi-
rect proof of the very inferior antiquity of
man on the earth.
SCIENTIFIC COOKERY.
Liebig, in his Chemistry of Food, recon-
mends the following method of cooking
meat on scientific principles. Put the Joint
into water in state of fast ebullition allow
it TO remain in this state for few minutes.
and then add SO much cold water as to re-
duce the temperature TO about 100 degrees,
