The scientist declare that ninety per
cent. Of man is water.
Tho best of rules, sextants, quadrants.
compasses, lances and knives aro made
OF worn out saws.
A man at Hartford, Conn.,, received a
shock from an electric wire, and was
supposed to be dead for somo miuutos.
but was revived by another shock.
a workman in tho Carson (Nev. mint
has discovered that drill points,
heated to cherry red and tempered by
being driven into bar of lead, will bore
through the hardest steel or plate glass
without pcrccptible bunting.
Analysis of natural gas shows the pro
portion of each constituent in 100 parts
of tho gas to bo as follows: Carbonic
acid and carbonic oxide, q each; oxygen,
8; olonant gas, Il; ethylic hydride, 8
marsh gas, 81; hydrogen, 90; nitrogen, 3.
1t has been estimated by Professor
Kirchoff, of Halle, that the language
most spoken on the globe-for tho last
thousand years, at loast-is Chinese, for
1t is without doubt the only ono which is
talked by over 400, 900, 900 of the human
race.
The use of electric motors as q substi-
tuto for the steam engine is rapidly in
creasing. In cities which arc provided
with IN electric lighting plant, the dy-
namos can be used during tho day to
furnish n current for operating motors in
workshops and small factories ut n less
expense than that of steam engine.
In calico printing works it is custom.
ary to supply each printing machine with
separate engine to drive it. Ono roa-
SON for this arrangement is that every
time fresh pattern is put into the ma
chine it requires to be driven with ox-
ceeding slowncss, and is frequently
stopped until the attendant has adjustcd
all the rollers, 80 that the various parts
OF the pattern fall exactly In the right
place.
An instrument called tho ostootome
has been invented rs an improvement
over the tedious and clumsy surgical
methods of cutting through bones by
by means of saws and ch.sels. 1t is
practically ci cular saw revolving nt
very high speed by an electric motor.
AN ingenious devised sh cid, which
passes around the bone to be operated
upon, protects the surrounding flesh
from injury.
a French gardener does not caro- what
kind of soil he starts with. lIIe would be
satisfied with an asphalt pavement, be.
cause he makes his soil, nnd so much of
it that ho has to sell it to keep his place
from being gradually raised above the
level of tho surrounding country. When
q farmer once understands tho laws OF
chemistry he has no difficulty in making
soil that contains all the materials needed
for plant life.
Heavy machinery is now run by nr.
tcsan-wcll power in many pnrts OF
France, and the experience of tho French
shows that tho deeper the we'll the great.
or the pressure and tho higher tho tenn.
pcraturo. The famous Grcncllo well,
sunk to the depth of 1900 fcot and flow
ing daily 800, 0O0 gallons, has pressure
of sixty pounds to tho square inch, tho
water being also so hot that it is used
for heating the hospitals.
An ingenious employc of Now Jcr-
soy concrete firm has invented pnving
composition which has some very ro.
markable features. IIc claims Tint his
preparation, the composition of which
he Keeps secret, is just rs durable rs
stone, but is soft and elastic to the tread,
so that it is not only pleasant to walk
upon, but actually gives the foot an i'm
pulse like that-in lesser degree of
conrse-gaincd from spring board.
Whether his invention be possibility or
not, something of the kind would Ger
tainly be acceptable to tired townfolk
whose feet ache and blister rs they stamp
along on the hard and noisy pavement
