SCIENTIFIC GLEANINGS.

The electric lights on the Eiffel Tower
can be seen at Orleans, seventy miles dis
tant.
An electric spark has been photographed
by means of a special camera, in which
the sensitive plate rotated at, 1t Is said, a
velocity of $500 revolutions minute.
A German authority affrms that oaks
are more frequently struck by lightning
than beeches, because the leaves of the
beech are covered with fine down which
is better conductor of electricity than
the smooth leaves of the oak. Expert
ments with electrical machines confirm
the theory.
Strangers travelling through or sojourn-
ing in districts known to be Astounding In
malarial fevers and ague, says Medical
Classics, should dress In flannel clothing,
avoid raw fruits, open air bathing and
night air, and drink tea and coffeee, or
only water that has been previously boiled.
1t is stated that in one establishment in
Cincinnati the large number of 81 600
gold dollars are annually beaten out into
gold leaf statement not more remark
able than the fact, as it is also asserted
that as many as 400! thicknesses of the
gold leaf are required to equal sheet of
thin paper and $780, 900 to form an inch.
r2Aratifcial silk is not yet manufactured
ON an industrial scale, but it appears that
this will very shortly be done, and, while
it is impossible to foretell with certainty
what will be the commercial results of
this curious invention, it is highly prac-
ticable and that it even contains the ele-
ments of great future success.
In fifteen cases investigated after light
ming has struck a building and done more
or less damage, it was found that in nine
cases the discharge made its way to earth
through gas pipes and in only one was
there any probability of the regular light
ming conductor having done It's duty.
Prof Lintner estimates that if all the
species of insects inhabiting the world
were known, their number would reach a
million, and, descending to the consider
alton of individuals, he adds that he has
seen at one glance, within a small extent
of roadway, more snow fleas of single
species than there are human beings on
the entire surface of the globe.
Prof. Fresenius of Wiesbaden, after a
long series of chemical analyses, declares
that an egg contains as much nourishment
as pound and an ounce of cherries, a
pound and quarter of grapes, pound
and half of russell apples, two pounds of
gooseberries and four pounds of pears,
and that ia pounds of grapes, 1877 pounds
of russell apples, 1872 pounds of pears and
1877 pounds of plumbs are equal in nourish-
ment to 100 pounds of potatoes.
The workings of the human heart have
been computed by celebrated physiolo-
gist, and he has demonstrated that it is
equal to the lifting of 1919 tons in twenty
four hours. Presuming that the blood is
thrown off at the heart at each pulsation
in the proportion of sixty-nine strokes per
minute, and at the assumed force of nine
feet, the mileage of the blood through the
body might be taken at 207 yards per min
ute, seven miles per hour, 1913 miles per
day, 81 800 miles per gear, or 5,150, $3.50
miles in lifetime of eighty-four years.
The number of beats In the heart In the
same long life would reach the enormous
total of 1880, 776,0 900.
Professor Stewart, after telling US that
the seat of nausea is not in the stomach,
but in the brain, informs US that relief
from this distressing sensation may be
obtained by cooling the base of the brain.
He has tested this often and thoroughly In
the case of sick headache, bilious collie,
cholera morbus and other ills in which
the nausea is distressing symptom, with
out single failure and once relieved the
nausea resulting from cancer of the stom-
ach by the application of ice to the back
of the neck and occipital bone. The ice is
to be broken and the bits placed between
the folds of towel. Relief may be obtain
ed by holding the head over sink or tub
and pouring a small stream of water on
the back of the neck This is worth re-
membering, as relief for sick headache,
to which so many women are subject.
