-Stonemasons will probably get a
better idea of the immense size of the
great pyramid when they learn that it
consists of s., 02s, 900 cubic feet.
Encouraged by the great success of
his milk depots and gratified by the
benefits conferred by sterilized milk in
saving the lives of sick children in New
York City, Nathan Strauss has decided
to erect permanent plant which will
be open the year round.
Water at high temperature cannot
be raised any considerable distance by
suction, as the vapor discharged from
the water so heated follows the reced-
ing pistons of the pump and resists the
entrance of the water; consequently.
to pump hot water always place the
supply above the pump, so that it will
be supplied from head.
The largest search light in the
world is now in operation at the gov
eminent proving grounds at Sandy
Hook, at the entrance to the outer bay
| of New York The estimated candle
power of the light is 94,000,00o. 1t is
claimed that its rays can be seen at
distance of nearly one hundred miles,
and that vessels can be detected at
twenty miles.
DR. Buisson, of Paris, is the author
of a pamphlet treating of a certain pre-
yention and cure of hydrophobia by
.vapor baths. The author has tested
his plans for years with, it is claimed,
utmost invariable success, and is so
convinced of its infalibility that he
offers to submit himself to incubation
with the virus of a rabid dog.
| --Neukirch, German engineer, pro-
quicksand the sand itself should be
turned into solid concrete by blowing
into it through tube by air pressure,
powdered hydraulic cement. The air
insures thorough mixture, and the
concrete formed in this way is very
satisfactory, though taking several
weeks to harden and requiring months
tie attain full strength. 1t is found
that the mixture of the sand and
cement occupies less space than the
sand alone before the operation! This
method has already been successful in
cofferdam construction and sewer work
in quicksand.
r.. j. Crosse has just registered a
trademark in Germany for new Their
mometer, in which toluol is substi-
tuted for the mercury and alcohol that
have been employed up to the present.
The advantages of such substitution
are claimed to be many. In the first
place, toluol is liquid of deep black
color, which renders the column very
visible: in the second place, the freezing
point of this liquid is very remote from
its boiling point, and, finally, it costs
less than mercury, and the manipula-
ton of it is attended with nodanger to
the health of the workmen. Die Natur
