The stingless bee, of which several
colonies have been discovered in the
island Of Montserrat in the West In
dies will be an object Of much inter-
est, as it Is believed that it's honey
producing capabilities will be greatly
improved in modern hives.
Natural granite pulverized and
shaped by pressure and heat was used
at first for ornamental blocks. It has
been since found serviceable for cleo
trio insulation, and its resistance to
acids and chlorine have now given it
a place for lining sulphite digesters for
treating wood pulp.
A '1eather-sole fluid, proposed by E.
Soxhlet for preventing slipping con-
sists of 80 grammes of thick turpen-
tine, 200 grammes of colophony, 80
grammes of benzine and 200 grammes
Of alcohol, the mixture being allowed
to stand in a bottle in warm place
until the turpentine and colophony
have dissolved. The solution is applied
several times to the shoe soles Not
only is the slipperiness overcome, but
the leather is preserved.
Readings of the winds force are
transmitted electrically to a distance
by a new French instrument. The
spindle carrying the revolving cups OF
an ordinary thermometer also carries a
small gramme ring, which revolves in
the field of a strong permanent mag
net, and connection is made between
the coils of the ring and special form
OF voltmeter, whose graduationS are
adjusted to correspond to speeds of the
wind as measured by the thermometer
In an examination of the fluids of
S042 stomachs DR.. J. H. Kellogg has
found 1873 per cent to contain bacteria.
None exist when the food has been
sterile. Hydrochloric acid seems to be
less important in giving antiseptic
power to the stomach than has been
supposed, but it was proven that a
fruit dietary will sterilize the stom-
ach through the action of the vegetable
acids. In some cases of bacterial de-
rangement an exclusive fruit diet for
two days to a week may be necessary.
Any acid fruit may be employed, and
is more active raw than cooked. Ripe
bananas and even ripe olives, though
without marked germicidal power, may
be included in the fruit dietary with
advantage.
The production of cocoanut butter at
the factory in Mannheim, which dates
from 1886, has now reached about ten
tons per day. This material, which is
used as substitute for butter and
lard, Is claimed to contain SO per cent
of vegetable fat with only a trace of
water, while ordinary butter consists
OF 80 per cent of fat and nearly Is per
cent water. The price in Germany is
about half that Of butter. Cocoanut
butter keeps three or four months in
cool place, and it's wholesomeness
and digestibility are giving 1t a steady
gain in favor for baking and cooking,
especially for hospitals and army
camps. The processes by which the
Tat OF the cocoanut kernel is freed
from free acids and other substances
are mostly secret.
A new apparatus of Mr.. Sherard
Cowper Coles, a London physicist. is
designed to localize sounds rapidly
and to project sounds to q great dis
lance. 1t consists essentially of an up-
rtSght concave mirrow, suitably mount
ed, in the focus of which is fixed one
right concave mirror, suitably mount
piece at this end of the tube being
turned toward the mirror while one at
the other end Is free. The mounting
enables the operator to raise or lower
the mirror, or to turn 1t toward any
point. To find the direction from
which any sound comes, 1t Is simply
necessary to listen at the free mouth
piece while the mirror is moved until
sound reaches it's greatest intensity;
and for sending forth speech or other
sounds the free mouthpiece serves as
long distance may be carried on be-
the apparatus.
