m. n. keumann OF Zdficb has dis
covered that when sulphur Is heated
just sutiOiently to combine slowly with
the oxygen Of the air, but not high
enough TO enter into this combination
J with rapidity, It exhibits a very brill-
iant pbosphoreseeDce, far surprising
that Of bosphorus.
i The opinion is said to be gaining
ground among metallurgists that what.
ever mechanical strength is desirable,
an alloy Is preferable TO pure metal.
One Of the greatcst-obstruetions to the
mecbanieal vAlueo Of iron is It's tendency
70 crystalIize, the resaI. being the
same whether the article be monster
gan or . ships cable. Bot this ten
dency Of iron to crystalline may be pre-
vented BY tbs adnixtafe Of other met
al.
In recent treatise Dr. l. Manouy-
rier, French crsnioIogist, states that
the crsnium is heavier in negro races
than in any others that have been sui
Jeeted to comparison, 90 that the pro.
verbal thickness of the negro's skull
has foundation in fact. The skulls
Of Pspusns and natives Of New Gale
donia are heavier than those Of Paris
ians, while those Of American abori-
gines and the Bengalese are lighter.
The weight Of the female Uranium is
about one.seventh less than that Of the
male.
Prof. Pocrtor reasons that the moon
has grown old SIX times a. fast as the
earth, a comparison Of the masses and
rAdiatipg surfaces Of the two bodies
making it evident that the ezrtb's in
ternaI heat was originally sufficient to
last six times a. long as the moons
supply. On the very moderate assump-
tion, therefore, that only II, ,000, 900 If
years have passed since the earth and
the moon were at the same stage Of
planetary life, this astronomer shows
us that 60, ,000, 600 of years must eIapse
before the earth will have reached the
stage Of life through which the moon is
now passing.
Experiments made some time ago by
Prof. Dcremus have shown that gas
viii readily pass through stone. A
block Of brown sandstone, l2x45 inches
long, and four or FIVE inches thick, was
used. A pipe was clamped on to the
stone by means Of iron plates, and this
PIPE connected by means Of flexible
tubes with the gas pipes. The remain-
5 der Of the stone was painted over sew
. eral thicknesses with varnish. 0ppo-
site TO tbs point where the gas was ap-
piled there was another pipe for the
] gas 70 escape from. In few minutes
lighted paper applied to it caused &
8 fame to appear, showing that the gas
4 had passed through the stone.
/. The spectra Of solar and stellar phys
ic seem to show, according to the re-
+ Gently expressed opinion Of certain as
q tronomers, that the elements them
I selves, or at least some Of them, ara
Q compound bodies. From this it woulC
o appear that the hotter star the NOR
= simple is It's spectrum, for the brightest
and therefore probably the hottest stars
o such as Sirius, furnish spectra showing
g only very thick hydrogen lines, and I
9 very few thin metallic lines, character
d istic of elements of low atomic weight
r On the other hand. cooler stars, sucl
q as the sun. are shown by their spectrs
h to contain g much larger number o
d metallic elements than stars such a
= Sirius, ont no non-metAllic elements
Perhaps, as the temperature increases
It the compounds are 6rst broken up int

{ then undergoing decomposition int
0 elements of lower atomic weight.
