s Monkeys, UIDl1feSl
sIsually divided irto threc -
inopkeys and baboors but these do not
include the American monkeys, which arc
really more different from ali those Of the
Odd World than any of the latter are from
each other. Naturalists, therefore, divide
4 he whole monkey tribe into two families,
soue having its habitat in the Old World
and the other in the New World.
+ An old gun, supposed to be a Spanish
arm of the fifteenth century, has been
72ken mp out of the harbor at Santsnda.
Some resemblance can be traced between it
and an English gun, known to be of fif-
secnth century origia, in the rotunda mu.
scum at Woolwicb, a very old gun taken
II the last Chinese war, and gun which
belonged to q vessel of the Spanish Armada.
: It is of wrought iron, is breech.loadeA
about thirty-six cslibers long, and has TO
provision for recojl.
There Is 81 impression abrosd sHfosgelee--
tricians, both OF the theoretical and the
practical side of the house, that in the
near future there is much more to DO
gained in turning to the best account past
discoveries than in trying to make new
ones. This is what L'Eiectricite has be-
gun to say Of those who would lie their
own biographers and take very good care
not to underrate themselves "BslI does
not efface Refs Faure cannot destroy
Plante, and Swan, Edison, and the Others
cannot suppress the anterior labors of
Chanzy."
When alkalis are present in nitrate Of
silver, Herr Stolba recommends the salt to
be dissolved in q very small quantity Of
water, and after the solution is filtered,
drop by drop Of hydrohuosilicic acid is to
be added to it until turbid appearance
occurs The maintenance OF limpid state
after the application OF the acid is not con-
elusive. Finally, an equal volume of alec.
mol must be added, and then, if there is
the slightest quantity OF Glkali in solution,
there will be a precipitate.
a new gas-lamp with two pipes has been
successfully treated in England. One pipe
supplies gas IN the usual way, and the
other furnishes air Slightly compressed
by the weight OF column of water
Upon the burner is cap of fine platinum
wire gauze, which, a few seconds after the
current of mingled gas and air have been
ignited, gives brilliant incandescent glow
like that of the electric lamp. Arrange
merits have been made for lighting several
London thoroughfares with this light,
which. it is asserted, is cheaper than the
ordinary gaslight.
The question of the existence of earth
tides, or oscillations of the earth's crust
corresponding to those produced in the sea
by the attraction of the moon, ia being
investigated by British commission. A
pendulum is so suspended that its slightest
motion turns mirror and causes the point
of ErrhE roHaotEA 1xr ant
screen to move very perceptibly The
pendulum is proved to be in continual
change of position, for the motion OF the
reflected light is incessaut, and so irregular
that it is hardly possible to determine its
mean position or the screen within FIVE or
Six inches.
The Government method Of cleaning
brass, and ia use az al the United States
Arsenals, is Claimed 20 be tie best in the
world. Tie plan Is 70 make a NIX lure Of
one part common nitric acid and one.half
part snlphuric acid, in stone jar having
also ready pail OF fresh water and u box
of sawdust. The articles to be treated are
dipped into the acid, thep. r6moYa5 into the
water, and finally dubbed with saTdrst.
This immedy-ely changes them to a
brillians/5oler Ii the brass has become
qraaa,5, il isifirst dipped IN strong soIu-
tioa of potath and soda in warm water
this cuts tho grease, so that the acid has
free power 10 act.
Msssey's steam hammer, lately invented
ia England, differs from the ordinary ham
mer in its frrming It has been customary
to make the lower part OF the framing Of
hammers in sgrought-iron, consisting of two
pillars aud ia girded beam, and then to
build on this superstructure of cast-iron
which carrirs the cylinder, and this cast
iron part is, sof course, as much subject to
breakage as before. In the Massey ham
mer the upper as well as the lower part of
the framing is of wrought-iron, cast.iron is
only used for the slides, and go introduced
that it may be removal altogether with.
out destroyitg the framing. The wrought
iron also is in the form of girders put
together on patented system, thus
avoiding any transverse joints. Tho
fanges, With are bolted upon the baso
| plate, are wrought instead of cast.iron.
Altogether, the hammer has about as
strong frataing as it well could have.
