in the course of an investigation,
part of which has already been COM
municated to the Royal society, Prof.
Roberts-Austen has discovered the most
brilliantly colored alloy as yet known.
It has rich purple color, and bright
ruby tints are obtained when light is re-
fected from one surface of the alloy to
another. It contains about seventy
per cent. of gold, the rest of the alloy
being aluminium. Y. Ledger
Flinders Petrie has made another
''find" in Egypt, at Maydum, where he
has unearthed the oldest Egyptian tenn.

and the only pyramid temple yet dis
covered. It was buried under forty
feet of rubbish and belongs to the old

"A magnet carried by Newton in a
finger ring is said to have been capable
of raising TAG grains, or about $50 times
it's own weight of 8 grains, and to have
been much admired in consequence. A
magnet formdrly belonging to Sir John
Leslie, and now in the physical collec-
ton at Edinburg, has still greater
power, however, weighing 81 grains
and being able to support 1850 grains.

The majority of people die sooner
than they should. George E. Warner,
jr, says: "Disease is not a consequence
of life; it is due to unnatural conditions
of living-to neglect, abuse and want. -
And Dr. Stephen Smith says: MAN is
born to health and longevity; disease is
abnormal and death, except from old
age, is accidental, and both are pre-
ventable by human agencies"
Large quantities of onions are
brought to this country from Egypt, as
many as 50, 900 bushels often arriving al
New York in single week. They are
not equal to the onions grown in this
country, being small and yellow, but
the price in Egypt is SO low that, after
adding freight charges ard duty OF
forty cents bushel, they are sold here
for two dollars or two dollars and a
half bag of nearly two bushels
The mining departments of the min
istries of imperial property and of the
| interior have sent three engineers tC
America to study the methods by which
gold is worked out in the mines of Ari
zona, Colorado, Nevada, California anG
Utah. The yield of the Russian gold
mines has been very poor of late, an6
the raising of the price of labor as wei
as the rising of Russian values in the
| foreign markets has made the mining
of gold almost improbable. 1t is be
| lieved that the introduction of American
methods of mining will improve th'
miners trade.
The most important improvement!
in practical medicine in the United
States of late years have been in sur
gerry in its various branches. Thi'
country has led the way in the ligatior
of some of the larger arteries, in the re
moval of abdominal tumors, in tht
treatment of diseases and injuries pc
culiar to women and of spinal affec
tions, as well as deformities of various
kinds. Above all, we were the first t.
show the use of an8sthetics-the mos
important advance made during tn
century.
