aluminium and magnesium have re-
Gently been combined In Germany to
produce an alloy which does not rust,
and which Il a. light and tenacious a.
pure aluminium, while 1t can be worked
with the file and the lathe. It is named
magnalium.
Dr.. Ludwig Mond has discovered q
method for producing Illuminating ga
and coA gas at an expense Of 4 cents
. thousand feet It II thought that this
win effect q revolution by cheapenine
electric power and It will also have an
important bearing ON the production Of
open-hearth steel.
The suns surface 10 known to be sub
ject to greatly increased disturbances
every eleven years. known as the sun
spot period. Auroral displays and die
turbances Of the earth's magnetism
have similar period, and the pictures
OF the corona which have been obtained
show markedly Characteristic varieties
OF form dependent also upon the sun
spot period. So one Of the principal
efforts Of scientists Of late years has
been to obtain pictures Of the corona
with as much detail as possible.
A remarkable discovery by Captain
II. p. Deasy, In the Kuenlun Noun
tains, IL that Of species Of marine
plant, called grasswrack, ct an eleva-
ton Of 16.50O feet, more than 10000 feet
higher than the summit Of Mount
Washington. The plants were not
growing, but were found, with their
leaves and fruit, deposited In bed ten
OF twelve feet thick, which was COW
cred and Interpreted with strata Of
blue clay. The explanation offered d
that the deposit once formed part Of the
bottom Of q salt lake
Mr.. Beddard. Of the London zoologi-
cal Society, calls attention to peculiar
ity Of the carr Of tigers which he thinks
may be CHASED under the head Of pro
tective martings." On the back OF
each ear II very bright white spot,
and when the ears are directed for
ward these spots are conspicuous from
the front. Mr.. Beddard suggests that
when the tiger n sleeping In the dim
light Of q cave or thicket the spots On
its ears may appear to an enemy, look
ing In, as the CLEAN Of It's w&tchful
eyes, and thus save the sleeper from
an unexpected attack.
The earthquake waves due to the Jap
anese shock Of June 10, 1895, were re-
corded on the self-registerin9 tide
gauges at Honolulu and at Saucelito. Ii
the bay Of San Francisco. Dr. Charles
Dawson has recently compared the cal
culated velocity Of the earthquake
waves with the velocity formerly cal.
culated from the usual formula. ne
found that at Saucelito, for example.
the FIRST crest Of the waves reached the
tide gauge ten hours and thirty-four
minutes after the shock, having tray
ersed IN this time the distance Of 4,7S7
miles at an average velocity Of ga feet
Z second.
It has been observed that on account
Of the absence Of IN atmosphere ON the
moon. and the consequent lack Of grada-
ton In shadows, the eye Of the observer
- seriously misled IN judging the actu-
a relief Of objects forming the lunar
landscapes. Professor Prinx, Of Brus.
sells, has recently developed method
Of avoiding this difaculty. and OF seeing
che craters and other details ON the
moon in their natural proportions. TAX
Ing advantage Of the fact that a. the
moon travels around the earth the e.
cenricity Of ito orbit produces the ef.
feet Of q slow filtration, or balancing to
and fro. which causes it, face to be
inclined now little one way and now
. little the other way. Professor Prinx
makes two photographs Of the lunar
object to be studied, atopposite points, in
the libration, and then combines them
In sterecscope, whereupon the object
stands forth In full relief. This prtn-
ciple has hitherto been applied only to
photographs Of the moon a. a whole.
and mot to particular craters or regions.
