movable tilteripg bottom. Steam is let
in, and, passing through the mud drives
out the moisture and alkali through the
filter bottom. The bottom is then
lowered and the dry cake of carbonate of
lime is tilted into wagon and used in
plack of limestone in the black ash fur
mace.
POTATO BRANDT.
The United States consul at La
Rochelle gives French brandies a bad
name. He says no pure brandy is now
made in Cognac and the adjacent district.
German alcohol, made from potatoes, is
made up into something resembling
brandy, and the effects of it are very
pernicious. He says: @ Its characteris-
tic effect is to produce an intoxication in
which the patient is especially inclined
to rage and physical violence, while
hopeless insanity is the inevitable conse-
quence of persisting in it's use, even for
relatively short period of time. Alcohol
from potatoes contains fusel oil, which
is slow poison.
PARCHMENT PAPER.
According to a foreign journal @
strong, impervious parchment paper is
obtained by thoroughly washing wooden
or cotton fabrics, so as to remove gum,
starch, and other foreign bodies, then
to immerse them in bath containing a
small quantity of paper pulp. The latter
is made to penetrate the fabric by being
passed between rollers. Thus prepared,
it is afterward dipped into sulphuric
acid of suitable concentration, and then
repeatedly washed in bath of aqueous
of
been removed. Finally, it is pressed be-
liquid, dried between two other rollers
which are covered with felt, and lastly
calendered
PHoTOGRAPHING THE INTERIOR OF A
BOILER.
Photography of the interior of boiler
by the electric light is reported in the
Manchester, England, Times. The
boiler was at the marine exhibition,
Tynemouth. The water used in the
boiler was very hard, forming scales
quickly. When the boiler was opened,
the scales fell to the bottom, the CORFU
gated tlues having stripped themselves
from scales. The appearance OF the in
terror was such as to make a photograph
desirable. The pictures made by aid
of the electric light were entirely sue
cessful, and showed that the interiors
of machinery can be taken In this way.
The patentees claimed that the fues
were self-stripping, and this experiment
helps to confirm their assertion.
A WARNING LAMP.
There is story related of an old maid,
who for twenty years looked under her
!
bed for burglar, and finally found one
to the great arrangement of her nerves.
For such timid people an Englishman
has invented a new warning lamp"
"Upon door or window being moved,
after the apparatus has been set and the
lamp lighted, a red glass disc is released,
aud red or danger signal is given" AS
the nervous householder would have to
sit up all night to see the red light, it is
doubtful whether this invention will
come into general use. But if it were
adopted, imagine the feelings of man
who should awaken suddenly in the mid
die of the night and gaze at the baleful
red glare which announced the presence
OF burglar IN the house.-BoSton

FACTS ABOUT TOOLS.
When we study the construction Of
our most important implements, we dis
cover, to our astonlshment, that the lat
ter are true copies of some part of our
bodies, and simply further completion
of them. In the first stone hammer,
man has unknowingly initiated his fore
arm and closed fist; in the shovel and
the spoon we see the forearm and hol-
lowed hand; in the saw we find the re-
production of row of teeth; tongs rep
resent the closing together of the thumb
and finger; in the hook is reproduced
the bent finger; the pencil is simply a
proIOngatlon of the fore-fnger. So we
see, in all instruments, from the SIM
plest to the most complex, only an i'm
provement and completion of the human
organs; and thus we find that all inven.
tional thoughts of men are directed to-
wards the same aim as that toward
which organic development tends.-Sc5-

zOOPRAXISCoPICAL.
| Bostonians are listening to lectures il
Illustrated with 'zoopraxiscope. The
zoopraxiscope is the instrument with
which instantaneous photographs are
taken of animals III motion. It is COM
mon photograph camera in front of an
electric exposer. This exposer is pro-
vided with panels, with hooks attached,
and which are alternately opened end
closed with great rapidity by the electric
currents. The whole apparatus consists
OF twenty-four cameras and exposers,
placed twelve inches apart from center
to center, the whole continuance being
set up parallel to given track, across
which strings run twelve inches apart.
Each string is connected with one
camera, and, as the animal proceeds
along the track, he breaks the strings,
each break closing one circuit and ca1s-
ing one negative to be made. In pass
ing over the twenty-four feet there are
twenty four different pictures taken,
each exposure being not more than
1-5,000th part of second. The exact
position of the animal is thus shown
once in every twelve inches of his pro-
gress.
