Nutmegs in the quantity of two or
three drachms will cause both stupor and

Oyster shells laid on the hot Goals in
a stove or range will loosen clinkers on
the firebrick, so that they may be easily
removed.
It is stated by an actor that the elec-
trio lamp used as footlights is harder on
the eyes of the performers than either

Numerous experiments to determine
the best fire. resisting materials for the
construction of doors have proved that
wood covered with tin resisted the fire
better than an iron door.
The main elements in the makeup of
the world are oxygen, nitrogen, hydro
gen, chlorine, carbon, auorine, phos-
phorous, silicon, sulphur, aluminium,
calcium, copper, iron, lead, potassium
and sodium.
Oysters come nearer to milk than all
most any other common food material
as regards both the amounts and the rel
ative proportion of nutrients, the food
values of equal weights of milk and oys.
ters being nearly the same.
1t is somewhat singular that, notw ith.
standing the great advances made in
chemistry and metallurgy, no other more
satisfactory silver alloy has yet been dis
covered for coming and other purposes
than the alloy used 500 years ago.
The best lighted city in Europe is
Milan. American machinery only is
employed in its two central stations. A
curious feature of the system of distri-

In summer at Paris the Slene delivers

Neuf about hundred cubic inches of
water every second, moving with a force
of $500 horse power. Every hour
$50, 900 cubic metres OF water pass un.
der the arches of the bridge, or $780,
600 cubic metres in day.
A Roman has offered King Humbert
a novel instrument of warfare. This is
a projectile, which on being shot from
cannon and striking an object will
produce luminous disc of 10000
candle power, and thereby expose to
view an enemy's position by night at
distance of from three to four miles.
A miniature thunder factory has been
constructed for the science and art de-
partments at South Kcnsington, Eng
land, with plates seven feet in diameter,
which, 1t is believed, would give SPARKS
thirty inches long, but no Leyden jars
have been found to stand the charge, all

NJ. Bourdelless Chief Engineer of
French lighthouses, has perfected sys-
en- by which he can project force of
$500, 900 candles by means of four lenses
instead of twenty-four, as previously,
and by novel system of rotation make
the "fash" every twenty seconds. This,
the inventor claims, is the finest result
yet achieved anywhere.
Electric light baths are among the
latest inventions. The necessary parts
of such bath are a cabinet which will
inclose the entire body except the head,
and fifty electric lamps of sixteen candle
power, or Ito volts, arranged about the
body in groups, with separate switch
for each group. The light is thrown on
section at time, making the patient
frisky and browning the skin like an
ocean bath.
