Curiosities and Discoveries In the World Of
Progress


At q meeting of the Royal Geoloei-
cal Society at Cornwall, England, Pro-
fessor Warrington Smyth drew atten-
tion to the temperature OF deep mines,
especially those of Nevada, the great
heat of which he ascribed to chemical
changes going on in the lode itself.
1t is reported that Professor y. Sars,
of Christiania, received two years ago
some mud taken from the bottom of an
Australian lake by Norwegian geolo-
gist. Recently he placed the mud in
small aquaria and succeeded in pro-
ducing from it quite fauna of Aus
tralian fresh water invertebrates.
Tobacco plantations in Southern
| Hungary have sustained great damage
from the wire worm. This destructive
pest enters the stem of the tobacco
plant just above the root and works
its way upward TO the flowers. Plants
thus attacked yield no tobacco, us tho
leaves turn yellow and very soon fall
of.
Vaseline is said to be good preserv-
ative for eggs. The vaseline is melted
with three per cent of salicylic acid
and rubbed on the eggs after they are
thoroughly washed. The coating so
given may be renewed after while.
AS the air is thus thoroughly excluded,
the eggs. if they are fresh to begin
with, ought to keep good for long
time.
A claim has been advanced in favor
of Athanasins Kircher in connection
with the origin of the germ theory of
disease. In his work on 1.-The Plague"
published in Rome in 1868, he attrib-
utes the origin of epidemic disease to
animalculea (germ p and maintains
that each kind of putrefaction possess
cs a peculiar virus which produces a
definite knid of illness.
Mr.. w. ii. Prcece says that his ex-
periments have proved that the lumin-
Gus power of an electric glow lamp
increases as the sixth power of the in
tensity of the current. AS the energy
expended increases only as the square
of the intensity, the luminous power
varies as the cube of the energy ex-
pands; but the duration or life of the
lamps diminishes rapidly with the in
crease of light.
Rolled gold is thus manufactured
An ingot of brass is cast, and while it
is yet hot thin layer of gold alloy IS
poured upon it. When the ingot thus
covered becomes cold it IS forced be-
tween steel rollers until a long thin
ribbon is produced, of which the pro-
portion of gold and brass is, OF course,
the same rs that of the ingot. The
percentage of gold is often reduced
very low sometimes to two and three
per cent. This rolled gold in cheap
bracelets and watch chains lasts for ten
years.
Waste sands of glass factories often
accumulate in vast quantities. M.
Hignette shows how new ceramic
product capable of resisting acids and
atmospheric influences, is made from
such material. The sands are sub
jectod to heavy hydraulic pressure to
form blocks of various shapes and
sizes, which are then baked in furnaces
at high temperature. These blocks
have uniform white color. withstand
crushing load of nearly $40 kilo-
grams per cubic centimeter, and have
specific gravity of only 1.5.
Soil covered with living herbage or
} with such dead vegetable matter as
leaves, straw, wood, dung, &c, says
Prof. +. Wollny, is warmer in winter
and cooler in summer than bare soil
: under similar conditions. The differ
J ence of temperature is greatest in
summer and least in spring and
autumn. Bare soil heats more quickly
} in spring and cools more quickly in
autumn than that covered with living
| or dead vegetable matter. The fluctu-
= ations of temperature are much smaller
/ in covered than in hare soil
