SCIENTIFIC MISCELLANY.
Notes Of ADVANCE In the Wonder Arc Of
the World.

INTELLECTUAL INFLUENCE OF THE Nose
-Aprosexie Is the name DR.. Guye, Of Am
sterdam, chooses for inattentiveness, and b.
quite singularly finds that the nose Is on,
cause Of 1t. A dull boy became quick K
learn after certain tumors had been take1
from the nose; and q man who had beer
troubled with vertigo and buzzlng in thu
ears for twelve years found mental labol
easy after . like operation. In 1 third case
. medical student was similarly relieved
DR.. Guye supposes that these nasal trouble.
affect the brain by preventing the cerebral
lymph from circulating freely.
BOILERS EXPLODED BY GAS. After pro.
longed official investigation, the most extsn.
sive and complete destruction of steam
boilers on record has been attributed to the
sudden ignition of coal gas, mixed with cir,
that lad accumulated in the aues. The
explosion occurred July rs, 1887, in Upper
Silesia, Germany. twenty-five boilers,
each with more than 1000 square feet of
heating surface, were instantly blown to
pieces, buildings covering half an acre were
destroyed, and three men were killed.
WASTE OF ENEReY.-In the ordinary
sixteen candle power incandescent lamp,
according to Prot. E. Merritt, only from four
to six per cent. of the energy actually ex-
pended is available as light, the remainder
being wasted as heat. To lessen this loss is
one of theg greatest electrical problems .i,ow
awaiting solution.
FUTURE SCIENCE.-"What would one not
give" asks Lubbock, "for q science primer
OF the next century? for, to paraphrase a
we'll known saying, even the boy at the plow
will then know more of science than the
wisest of philosophers do now"

thermo electric circuit suspended by tor
sion fibre in a magnetic feld-shows & tenn
perature change of one tea.millionth of a
centigrade degree.
A MECHANICAL NovELTY.-The remark
able Mannesmann process of making seam.
less tubes is described by Mr.. F. Siemens as
consisting in passing the 1edbot bar Of solid
metal or glass between revolving conoidal
rolls. These rolls are so arranged that the
varying velocities of revolution with which
the different parts of the bar are brought
into contact cause the formation Of q hollow
through the bars centre. Tubes q foot IN
diameter, with a she'll only 3 quarter of an
inch thick, may be produced in this way,
and great strength is claimed for them.
Tubes with sealed ends may be made, the
hollow centre being q acuum.
The ELECTRIC AGE.-Prof. Elisha Gray |
that electrical science has made a
advance in the last twenty years
thar in all the 5000 historic years preceding.
More is discovered in one day now than in q
years of the middle ages. We
Ind all sorts of work for electricity to do.
We make it carry our messages, drive our
ring our door bell, and scare the
we take it as q medicine, light our
gas with it, see by it, hear from it, talk with
i, and now we are beginning to teach it to
write.
ONE YEAR CLocKs.-An important inn
,rovement in clocks, has been shown the
British Association for the Adv ancement of
by Mr.. W. Il. Douglass. The new
eature is the torsion% pendulum, which, with
and escapement, may be applied to
works, and by its slow rate of
'ibration makes practicable the conversion
f an eight.day clock into one requiring
only once a year.
PHOTOGRAPHIC PROGRESS, Among re-
ent camera achievements is a portrait COPY
by the light of a Cuban FREELY in
hirty seconds, and a photograph Of the
aurora Borealis. To obtain the latter had
cen declared an utter impossibility.
