SCRAPS OF SCIENCE.


THE deepest known worked mine Is IN
Australia--R shaft having been sunk
B,200 feet.
A MEMBER Of the French Academy Of
Sciences has discovered well marked
sexual differences In cells
SPECIMENS Of fossil woods and Ignite
are reported TO have been brought 10 tho
surface from the depth Of 19l feet while
boring an artesian well at Galveston.
Texas.
ExPERTAutNrs 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 a
row of gun cotton reaching from London
10 Edinburg could be fred In two
minutes.
REPnYINc 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 recent lecture that one
Of the most accurate descriptions of
somnambulism in existence was tha
sleep walking sceno Of Macbeth.
FoUR Jourdan glycerine barometcro
are now in use IN or near London. One
Is at Kew, in the museum of practical
geology, one at South Kensington, and
one In the office OF the London Times.
The enormous scale Of the barometer
enables changes scarcely visible in tho
mercuriRl instrument to be detected with
ease.
RossRrrI has found that the tempera-
ture Of the positive carbon Of the elect

| 5000 degrees centrigrade, and that Of
the negative carbon between 1880 de-
| grees and 9, 800 degrees, making. there
fore, the temperatures Of the extreme
points Of the electrodes not below 1900
degrees and 5000 degrees.
EXPERIMENTS have been made on ami
mails with pure hydrocianic ncid by NJ
Brame The bodies Of those killed with
il remained unaffected by decomposition
for about a month. During that time
the acid remained in the tissues. and
especially In the stomach. 1t 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 81. Peters
burg Technical Society, Prof. Beilstein
recommends the use Of Bulphate On
Rlumnia az the best practical disinfec-
tant. He states that tho best method
Of making the salt for disinfeeting pur-
poses is 70 mix red clay with four per
cent. Of sulphuric acid and TO add TO tho
mixture some carbolic acid for destroy
ing the smell Of the matter TO bo disin-
fected.
A SCIENTIST in the Magazine Of PhGr-
naov asserts that tho 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-gl glasses
used by psychologists In their inocula-
ton experiments, before any really sound
and valuable knowledge can be gained
by the examination Of waters" as TO their
purity or impurity.
ALARM with indignation has arisen u
Halle regarding tarletans rendered pois-
onous by the introduction Of copper
Arsenite in their production. DIR. Rel.
man has attempted 10 allay the general
outcry by stating that copper aFsenite Ia
not splendid green color, and as fol
such goods as tarletans, Guignets green
which contains no arsenic, has quite dis
placed the poisonous Scbweinfurt green
THE authority for the statement tina
after the extraction Of the inter from
gunpowder the residue cannot be driec
at 200 degrees, without slight loss o
the sulphur, is Fresenins. Herr A
Wagner, on the contrary, rises from hi
experiments with the conviction that NJ
such loss has ever been observed at o
below the temperature given. Abov'
: that temperature the residue suffers
! notable diminution in weight.
