HIGH TEMPERATURES.-By concen.
trating the electricity from . IS horse
power machine into the space of half an
inch by enclosing carbon points in .
block of lime, Mr.. Edison claims to have
produced the highest temperature ever
reached by artificial means. When
dropped into the fame, pieces of iridi-
um, one Of the most refractory Of met
ais, volatized Immediately. A small
screw driver passed across the fame
would be cut In two, the part touched
by the heat melting instantly. Even
parts of the lime crucible fused under
the intense heat.
WHY GLASS IS BROKEN By Hot Wa
TER.-No person could be SO foolish as
to hazard the breaking Of q glass by
pouring hot water upon it, If he under
stood the simple means of accounting
for the breakage. If hot water is pour
ed into glass with round bottom,
the expansion produced by the heat of
the water will cause the bottom of the
glass to enlarge, while the sides, which
are not heated, retain their former d.
mansions, and consequently, il the heat
be sufficiently intense, the bottom will
be forced from the sides, and q crack or
flaw will surround that part of the glass
by which the sides are united to the bot
tom. II, however, the glass be previ-
ously wetted with q little warm water,
so that the whole is gradually heated
and thereby expanded, boiling water
can then be poured in without damage.
If q silver spoon is placed in agoblet or
glass jar, boiling water can then be
poured in without danger, unless the
article has been taken from . frosty
closet, and is very cold.-Springfeld

The TROPICAL PAwPAw.-A Ger
man naturalist, Herr Wittmach, has re-
Gently been making experiments with
the tropical fruit, the papaw, the juice
of which is found to possess the proper
ty when boiled with tough meat of rem.
dering it tender. II the unripe fruit be
placed in the water in which the tough
est meat is to be cooked, it is found to
effectually soften it and render it per-
fectly digestible; and the same results
are observed if the meat be merely
washed with the Juice of the fruit. The
thick, white, milky juice, when extract
ed from the unripe papaw, in fact, con-
tains properties similar to those of
pepsine. Hard-boiled white of egg, to
which few drops of dilute juice have
been added, has been found after "a
hours to be perfectly soft and easily
broken up, having undergone, in fact,
the same process as food digested in
the natural way. If taken in too large
doses, the substance is dangerous, hay
ing the effect of permeating and actually
destroying the thin mucous membrane
of the stomach and intestines. The
papaw fruit when fully ripe is about
seven or eight inches long, of q bright
yellow color, somewhat resembling a
citron or lemon, of the flavor Of which
it partakes in a small degree; an I'M
pleasant taste of petroleum, or. as de-
sclibed by some persons, of India rub
Der or turpentiue, however, pervades
the fruit.
WHOOPING-cOUGH AND FUNGUS
Some years ago NJ. Svetzerich made the
assertion that whooping-cough was
caused by certain fungus. This asser-
ton seems lately to have been confirm
ed by the researches of M. Yschamer,
VINO says he has found certain lower Or
ganisms in the spittle of whooping-
cough patients-organisms not met with
in any other disease accompanied by
cough and expectoration. Examining
the spittle after it has been q shor, time
suspended in water, there are found cor
puscles about the size of pins head,
of white or slightly yellowish hue, and
these show, besides apathetical cells, q
network frame of polygonal neshes,
with rounded greenish sporules; At .
more advanced stage, colorless hyphs
are seen, and large sporules, yellowish
or brownish red, sometimes even rami-
fed. 1t is interesting to learn that the
champignons in question are quite iden-
teal with thUse which, by their agglom-
Grafton, form the black points on the
skins of oranges and the parings of GER
tain fruits, especially apples. Thus, M.
Yschamer, by inoculatiog rabbits with
this dark matter, or even caQsing it to
be inhaled by men, produced fits OF
coughing several days in duration, and
presenting all the characters of the con-
vulsive whooping-cough. - Scientific

THE PARASITES IN PORK.-Cysticcr-
Gus ccllulosG, Familiarity known as
"measles I" in pork, on passing into the
human economy may develop into the
common tapeworm. Analogous en-
tozoa are sometimes found in beef, veal,
mutton, and other meats, but the great
source of these formidable parasites is
pork. They can be easily detected in
the carcass of q pig that is infected by
them. "They are in the muscles"
writes DR.. Vacher, in . paper read be-
fore an association of health officers,
s'between the fibers, between the mus
cles, on the surface of the muscles, and
even in the walls of the heart. {.
Specimens from the same beast" he
continues, are nearly of the came size,
but specimens taken from different
beasts vary considerably in size. The
egg shaped investing bladder is scarce
ly ever less than an eighth of an inch in
length, and it sometimes measures half
an inch, so that it may ne easily seen
and removed. It is semi-traasparent,
and contains q clear fluid, and what
looks like little white ball. On trans
ferring the bladder to . glass slip, .
touch with the point of knife will suf-
fee to rupture it, and il you then prees
. cover down upon it You have . prep
aration in which the rostellum and cir
clet Of hooks may be distinctly seen with
an ordinary lens" When meat is lit
tie dry from exposure to air the cysts
collapse. and ara not distinctly visible.
