BITS OF SCIENCE.

The newest use which has been made of
luminous paint is its application to
harness. By this means the position Of
the horse is pla1Giy, seen at night, and
the animal is not alarmed by his bright
equipment.
Professor BlOuBt has made some elab-
crate experiments in Colorado which
proves that the tendency Of foreign seed
IS to produce better grain than domestic
seed. 1t has also Deenl fOnRd that wheat
loses its gluten by age, and some yarie-
ties In much greater degree than others.
NJ. Girard, Director of the Paris NUM-
clpal Laboratory, says that the chemical
knowledge applied to the connection of
spurious foods and drinks is of a very
high order, and would suffice to make the
fortunes of the aduteratOrs a dozen
times over if applied in an honest ca
pacity.
For a disinfectant laundry blue mix
sixteen parts of Prussian blue, two
parts of carbOlie acid, one part of bOrax,
and one part OF gum arabic, into a stiff
cough. Roll it out into balls as large as
hazel nuts, ard. coat them with gelatine
or gum to prevent the earbOlic acid from
escaping.
The sand O. the Desert Of Sahara is of
yellow color, and consists of about 90
=
and per cent. of feldspar. Other MINER
ais found in it, but in very small quaint.
ty, are chalk, clay, balitz, sylvite, mag
netite, chromite, garnet, Divine, ampbi-
bole and pyEONene.
Leather wheels are made in France for
railroad and other ears. The inventoa-of
the process.is NJ. de la Roche. Unframed
buffalo hides are cut ihto strips, and
these are built up into solid discs, which.
are strongly held together by two iron
rings after, they have been subjected to
hydraulic. pressure.
Rabbits. have been born with ore ear
and stays with one horn; the rattlesnake
has but one lung; both eyes of the founder
and halibUt are on the same side; the
claws Of the lobster differ and the valves
OF the oyster are unequal, yet all the ami
mails and their organs are perfeo5ly SYM
metrlcal in the embryo state.
Oil of wintergreen mixed with an equal
quantity of olive oil, when applied eXter-
nally to inflamed joints affected by rheu-
matism, is maintained to be, on high
therapeutic authority, means of instant
relief from pain. AT any rate, its intro
dactiOn to the sick chamber is unObjec-
tf0nable, if only for the agreeable cdOr it
imparts to the atmosphere.
A correspondent of the London EEeetri-
elan gives the following as an instant
remedy for tOOthache: With a small
piece of zinc and bit Of silver (any sill
yer coin will do), the ziRc placed on one
side of the afflicted gum and the silver ON
the other, by bringing the edges together,
the small current of electricity generated
Immediately and painlessly stops the

Mr.. James Collins, writing upon Vegeta-
BILE, wool or silk cotton, says: For the
/ INN If - ofp
silk cotton seems to answer admirably;
but its want OF cohesion, or nOn-felting
qualities, renders it Of no use for spinning,
| except as a mixture to impart silky
! gloss to the fabric so mixed. Among its
advantages are its lowness of price, its
/ lightness, its very great elasticity and
sOftness, and the resistance it offers to the
! attacks Of insects"
I The analyses of snake pOisons made last
summer by Drs. Weir Mitchell and
Reichert have been fully confirmed by
other investigators. All OF the yenOms
/ examined are essentially alike; in every
case they are made up Of three prOteid
bodies. The first reduces the blood pres
sure, induces swelling (Wdema) and
finally brings about putrefactive effects.
The second is Virulent substance, one
twentieth OF grain of which will kill
pigeon in two hours, 1t gives rise in
lev IHluultS dlbeI lUJ6cblOH 10 enormous
infiltratiOn of blood into the neighboring
tissue. The poisonous properties of the
third substance'are doubtful. The object
of the analyses is to eliminate the veno-.
nous principle, so that experiments may
be made as to what drug can be used to
the best advantage in neutralizing it.
Camphor is made in Japan in this way:
/ After tree is felled to the earth it is cut
up into chips, which are laid in tub on
large iron pot partially filled with
water and placed over slow fire.
| Through holes in the bottom Of the tub
] steam slowly rises. and. heating the
! chips, generates oil and camphor. OF
| course, the tub with the chips has close
| ly fitting cover. From this cover a bam-
! boo pipe leads to a succession of other
! tubs with bamboo connections, and the
last of these tubs is divided into two com
| partments, one above the other, the di-
viding floor being perforated with small
| holes to allow the water and oil to pass to
the lower compartment. The upper COM
partment is supplied with a straw layer
which catches and holds the camphor in
! crystal in deposit as it passes to the cool
| ing process. The c2mphOr is then sep
arated from the straw, packed j" -
