Dana estimates the upward increase
Of coral reef TO be an average rate Of an
eighth OF IN inch n year. at which rate
more than 100, 600 years must have been
oceupied in the formation Of a reef 2 900
feet in thickness.
A recent course Of experiments made
TO Determine the heating power Of gas
shows that n cubic foot OF ordinary
sixteen-candle coal gas win develop 3ls
heat units. while water gas viii give
only about 1877 heat units per cubic
foot.
Swedish meteorologists have furn-
ished material for unlimited speculation
by preparing a catalogue of the auroras
e during the space Of more than
three centuries-that Is. from 1886 to
1877. The record shows that in the
period from 1722 to 1909 auroras were
observed on 4,246 nights.
Among matters Of prehistoric archaic
ology which OF late have attracted at
tention in Germany are the ..high-
fields" or .'heathen- fields" where the
marks Of ancient tillage are traced on
ground now waste or forest-grown.
These resemble the s'elf-furrows- Of
Scotland, but in neither country has
old agricultural race been identified
An examination was lately made Of a
quantity Of butter taken from an ala
baster vase found in m Egyptian tomb.
II had evidently been melted and pour
ed into the vase. which had then been
sealed. After $500 years the butter
had become only slightly rancid, and
had fully retained the chemical proper
ties, taste and general appearance Of
genuine butter.

Is one OF the Oldest monuments Of civ
~ilization in exittence, IL indeed 1t Is not
the very Oldest. II Is the lintel-stone
OF n tomb which formed the last resting
place Of an official who lived In the time
OF King Sent, Of the second Egyptian
dynasty, whose date Is placed by NJ.
Marietta more than six thousand years
ago. The stone Is covered with hero
glyphics and delicate and finished sculp-
ture.
Rivers aid in the distribution OF
plants by bringing down to the valleys
the seeds which accidentally fall into
the watsr. Thus the southern shores
Of the Baltic are visited by seeds which
grew in the interior Of Germany. and
the western shores Of the Atlantic by
seeds that generated in the interior Of
America. A more remarkable fact is
that the gulf stream has conveyed to
the western coast Of Europe the fruits
and seeds Of plants which are indigo
nous TO America In such a state that
they might have vegetated uuder favor
able conditions Of climate and soil.
The life Of Mafuka, who lived some
time at Dresden, is among the most in
structive Of PHOTOGRAPHERS, as Illus
trating the striking intelligence Of the
anthropoid. Knowing how to unlock her
cage with the key, she stole and hid 1t
for future use; she took the carpenters
brad-awl and bored holes with It
through her own table; when pouring
drink from a jug into her cup, she
would carefully stop short OF overfiling
IL. Her death had an almost human
pathos: she threw her arms around the
neck Of the director Of the gardens, Herr
Schopf, kissed him. and putting her
hand In his, lay down and died.
Tie malady commonly known as the
cholera Of fowls is caused by a minute
living organism. In its natural state
this organism is very fatal, but by n pc
culiar mode Of culture n. Pasteur, the
French chemist, claims to be able to
greatly reduce its virulence. II fowls
are inoculated with the attenuated
virus he produces they become sick, but
very few die, and those which recover
are ecu from the more virIlent form
OF the disorder. The fatal effects o.
the cholera Of fowls may thus be pre-
vented. NJ. Pasteur hopes to be abb,
to adapt his plan of artificial culture L
all kinds Of virus with the result Of SO
curing the means Of reducing the SO
verify Of all yirulent maladies.
