strong-one day, perhaps Put one
glove on the hand, dipa small wooden
cloth or sponge into the liquid, wet the
glove all over, rub it dry and hard un-
til it shines, and it will be nice pur-

stand on three-penny piece; it really
covers less space, for its base plate
measures only three eights of an inch
| by about three-tenths. From the ex-
trcme smallness of this model a few
minutia-such, for instance. as the
-pumps-have necessarily been omit
ted. Still, so small are some OF the
parts that they require a powerful
magnlfylng glass to see their form.
The screws are only oua>ei2ltl of an
inch in diameter, and th IL duly

of the model is less than a threc-pennv

working its crank shaft performs from

ExCENTRICITIEs OF NITRO GLYCERINE.
Nitro glycerine does not seem TO be-
come any more civilized as it mixes in
in scientific society. We read in a Ger
man publication an extraordinary ac-
count of the explosion OF only 10 drops
of this substance which pupil in a
laboratory had put into a small iron
saucepan and heated with q Bunsen
gas flame The effect of the explosion
was that the As panes OF glass of the
windows of the labOraTy were smashed
to atoms, the saucepan was hurled
! through a brick wall, the stout iron
stand on which the vessel had been
placed was partly split. partly spirally
4 twisted, and the tube OF the Bunsen
/ burner was split and Hattened outwards.
Fortunately none of tie three persons
! IN the laboratory at that time We're
hurt. When nitro glycerine is caused
/ to fall drop by drop upon thoroughly
red hot iron plate it burns of as gun
powder would under the same Condi-
! tions but if the iron be not red hot,
| but yet hot enough to cause the nitro
glycerine to boil suddenly an explosion
takes place.
/ CHEMICAL SUBSTITUTE FOR HUMAN
/ MGLK.-PrOfessor Liebig's chemical
substitute for mothers milk, which has
acquired such an extensive reputation
/ in Germany, is manufactured by the
/ following process; A half an ounce of
wheat flour is boiled with five ounces
of skinned milk until the mixture is
| transformed into a homogeneous mass;
/ 1t is then taken from the fire, and to
/ it IS Immediately added hall an ounce
! OF cross-spired barley, which must nave
been first ground in coffee mill, and
mixed with an ounce of cold water and
/ a arachm af a solution - Hi-CarhOuate
/ of potash, the latter in turn made
eleven parts of water to two Of potash
| After having added the barley. the yes
sci is placed III warm water or a warm
place, until the mixture has lost its
consistency, nd has become liquid lik
cream. 1t is allowed to repose for hf
! teen or twenty minutes, and Is then
placed on the fire and mace to boil for
| a few seconds, when it is removed and
poured through strainer of hair or
! thread, SO as to eliminate the tihrous
parts of the barley. The artificial milk
thus prepared contains, according to
Prof. Liebig, the plastic and respirato
ry elements essential to respiration and
nutrition of the body, in about the pro-
portion of from ten TO thirty eight on
the hundred-the same, according to
Prof. Liebig, as human milk.

The mill which is used for this purpose
consists of two sets Of rolls supported
. by the same framework, but each set
working independently of the other
Hydralic power is employed to press
the rolls together. The first set of rolls
consists of a single pair. The opera
ton of making the tire consists in
placing hammered ring containing
enough metal to form the tire between
the first pain of rolls In such a way that
! the ring encircles one of the rolls. Ii
IS then enlarged by rolling, and It's sec
ton formed III the same manner as q
straight bar would be drawn and shap-
ed IN ordinary rolling mills. The sec
Ond set OF rolls is similar to the first,
with the addition of two side rolls
mounted upon paIr Of jaws which
can be opened and closed Ivy toothed
segments operated by a worm having a
right and left hand thread. These rolls
finish the tire. Seventy tn eighty
horse power is required to drive this
mill, and the entire operation in It's va
rious stages is completed mt single

HERE is an establishment IN England
where the manufacture of artificial
granite is extensively carried on The
constituents OF this material are disin-
tegrated natural granite mixed with
clay, together with pounded glass, lava
and iron slags. The disintegrated
granite is obtained by submitting frag-
ments of natural granite to strong
heat, about seven or eight hundred de
erees, IN an oven, by which, after a
sufficient time, it becomes dissolved
IN to a granite sand, the component
parts of which, quartz or feldspar,
passess great powers of adhesion. One
part OF this granite sand is then mixed
with an equal quantity of pounded
glass-or the constituents of glass, lava
or iron slag-to which is added from
twenty to thirty parts of refractory
clay, or from thirty to fifty parts Of or
