SCRAPS OF SCIENCE.

THE deepest known worked mine is I'm
Australia shaft having been sunk
3, 200 feet.
A MEMBER of the French Academy OF
Sciences has discovered we'll marked
aexual differences in cells.
| SPECIdENs of fossil woods and Ignite
are reported to have been brought to tho
surface from the depth of 191 feet while
boring an artesian we'll at Galveston.
Texas.
EXPERIMENTS at Woolwich have DEM
onstrated that the transmission of deto.
nation from one mass of gun cotton to
another not in contact is SO rapid that O
row of gun cotton reaching from London
I to Edinburg could be fred In two
minutes.
REPLYING to the question whether or
not our ancestors were acquainted with
the peculiar physical condition known to
us as somnambulism, DIR. Reynard, Of
Paris, said in u recent lecture that one
OF the most accurate descriptions Of
Somnambulism in existence was the
sleep-walhing scene of Macbeth.
FouR Jourdan glycerine barometers
are now in use in or near London. One
is ut Kew, in the museum of practical
y II,
one in the Office of the London Times.
The enormous scale Of the barometer
enables changes scarcely visible in the
mercurial instrument to be detected with
ease.
RossErrI has found that the tempera-
ture Of the positive carbon Of the elect
rio arc is between 2,40O degrees and
5000 degrees centrigrade, and that Of
the negative carbon between $500 de-
J grees and 8, 900 degrees, making, there
fore, the temperatures of the extreme
points of the electrodes not below $500
degrees and $500 degrees.
EXPERIMENTS have been made on ami
mails with pure hydrocianic acid by M.
Brame. The bodies of those killed with
1t remained unaffected by decomposition
for about month. During that time
the acid remained in the tissues, and
especially in the stomach. It could be
easily settled to distillation, but much
more readily from the tissues of herbiv-
orous than Of carniverous animals.
In A communication to the st. Peters
burg Technical Society, Prof. Beilstein
recommends the use Of sulphate o.
alumnia as the best practical disinfec-
tant. He states that the best method
Of making the salt for disinfeoting pur-
poses is to mix red clay with four per
cent. of sulphuric ncid and to add to the
, mixture some carbolic acid for Destroy
ing the smell of the matter to be disin-
! fected.
:, A SCIENTIST in the Magazine of Phar-
!, MACY asserts that the usual physico-
chemical methods for determining the
potable nature of water have proved
themselves to be quite insufficient, and
he says that "recourse must be had to
the microscope and to the culture-glasses
used by psychologists in their inocuIa-
tion experiments, before any really sound
and valuable knowledge can be gained
J by the examination of waters" as to their
purity or impurity.
ALARM with Indignation has arisen il
Halle regarding tarletans rendered pois-
onous by the introduction of copper
arsenite III their production. DR.. Rel
man has attempted to allay the general
outcry by stating that copper arsenite is
not splendid green color, and as for
such goods as tarletns, Guignet's green,
which contains no arsenic, has quite dis
placed the poisonous Schweinfurt green.
The authority for the statement that
after the extraction of the inter from
gunpowder the residue cannot be dried
at 200 degrees, without slight loss
the sulphur, is Fresenius. Herr A,
Wagner, Oh the contrary, rises from his
experiments with the conviction that NO
such loss has ever been observed at or
below the temperature given. Above
that temperature the residue suffers o
notable diminution in weight.
