1t appears, from an article in a
French scientific journal, that analyses
have been made of articles found in
Egypt which show that bronze was in
use in that country more than two
thousand years before the Christian era
What is expected to be the second
largest bagging and cordage factory in
the United States is soon to be located
in Galveston, Tex. It will contain fifty
looms. and most of the machinery
be obtained from this country. although
the spinning and earding machines will
come from England. 2 of s49oftFs,f-
1t is believed by writer for the
Lancet that somnamhulism is in many
instances occasioned by worry and dis
tress of mind. and the action conse- :
quent thereon; ''some OF our actions
often becoming by practice so nearly
automatic that partial sleep or stupor
does not arrest their unconscious per-
formance.
A long continued series of observa-
tions, made both at Paris and Munich.
indicate that the sanitary condition OF
locality depends on its volume Of
ground water; that is. on the amount
of water contained in the ground. It
is stated that ''thc years in which there
has been a large quantity of grounds
water present have invariably been the
healthiest years. while those In which
there has been a small quantity have
invariably been the most unhealthy
periods. IN. T. Ledger. saiss ai8 tsl
According to Professor s. P. Lang
ley. the well-known American astron-
omer. the temperature of the sunlit
surface of the moon has been commonly
over-estimated,. and probably does not
exceed fifty degrees centigrade. Mr..
Richard A. Proctor, in his elaborate
work on the moon, says that, during
the lunar day, the surface, of the moon
burns, one may almost declare, with
heat of some five hundred, degrees
Fahrenheit. if the differences of our
most skillful physicists and the evidence
obtained from our most powerful means
of experiments can be trusted.
Chemically considered, man is COM
posed of thirteen elements-five being
gases and eight solids. In a man
weighing 154 pounds, the oxygen, ac-
ording to French authority, weighs 97
pounds, chlorine about 26 ounces, and
fiuorine 81 ounces. He is therefore
made up chiefly of gases, which in a
free state would occupy about 1900
cubic feet of space. Carbon and calci-
um represent the bulk of the solids; the
| phosphorus, sulphur, potassium, sodi-
um, and iron weighing only from II to
26 ounces each. 1raUeier.l

Lake Superior ports during the season
just closed aggregate 1872, 167 tom. as
compared with 3.443. 672 tons in 1885,
By ranges the shipments have been as
follows: Marquette range. l1.755.7
tons; Menominee range, 1,182,611 tons;
Gogebic range, I.091, ,335 tons; Vermil-

the shipments by lake from twelve OF
the larger producers among the mines
of the Marquette. Menominee and
Gogebic ranges, total being 2.s77, 166

German scientists are studying the
boomerang with view of discovering
the secret Of its curious course OF fight
At an exhibition OF boomerang throw
ing. at Munster, by a party Of native
Australians, some extraordinary facts
were developed. The boomerang was
ierked up into the air, and when 1t had
assembled about a hundred yards it flew
away in a straight line, then turned to
the left and returned in a curved line
back to the thrower, whirling around
constantly and whizzing uupieasantly.
One boomerang, owing to some fault in
the thrower, went astray, and coming
in contact with a spectators hat, cut il
in two as cleanly as q razor could have
done" This alarmed the scientists, as
, it was seen that any one sof.them might
possibly have. his head taken off by q
misdirected boomerang. IN. ?. Ledger.
