Ever since telescopes we're Invented
astronomers have been troubled in
their observations by the unsteadlness
of the air. Prof. S. Z. Langley has
lately pointed out surprising method
of getting round the difficulty. He has
shown, experimentally, that il the ale
In a long telescope tube Is vigorously
agltated. a quiet image of stars and
other objects will be produced. Photo
graphs OF telescope images taken in
this manner appear to justify Prof.
Langleys conclusion.
In Brussels. Malines and other Bel
gian towns, novel method of not
only getting rid of smoke. but turning
1t into use, has recently been employ
ed. The smoke is driven by ventil-
ating fan into a filter filed with porous
material, over which continuous
stream of petroleum. benzlne, alcohol
or some liquid hydroearbon flows. The
result Is that the smoke Is entirely sup
pressed. while the litter yields a gas
Of great calorlfc power. which can
be used for heating purposes and for
driving gas-englnes. The altering ma

The members of the Royal Society
OF Edinburgh were interested, at
recent meeting. In the announcement
by Messrs A. L. shlpley and Edwin
Wilson of the discovery of an appara-
tus, heretofore overlooked or neglect
ed. at the base of the mosquitoes
wings, whereby the characteristic
humming of that insect may be pro-
duced. The species examined was the
anopheles maculpennis. and the APP
paratus consists OF a slightly movable
bar provided with a series of we'll
marked teeth, which. as the wings are
raised and lowered. rasp across a series
of ridges. The structure of the APP
paratus Is described as very complex.
but the music produced. as everybody
knows, is extremely effective.
Mr.. Mar,onl believes that at some
future time-he will not tix a date for
it-wlreless telegraphy will become
available for domestic ard office use,

the aid of small models. or miniatures,
of his sending apparatus, as now erect
ed on a gigantic scale at Poldhu and
elsewhere. to transmit messages from

received In other rooms In the same
city, or In neghborlng towns. The

In the new Simplon tunnel under the
Alps. which will be by far the great
est tunnel in the world, having
length of fourteen miles, and which,
II Is now reported. will be completed
In July. 1905, the quantity Of watet
flowing out of the southern end. from
the many veins encountered in the
heart of the mountain. amounts to
$4,000 gallons per minute, and fur
nishes sufficient power to compress the
air by which the drills are worked.
and TO refrlgerate the tunnel The
necessity of refrigeration may be judg
ed from the fact that the heat In the
deeper parts of the tunnel rises as
high as 40 degree Fahrenheit when
not artlficlally reduced. Life would
be impossible In the tunnel, where
1000 workmen labor. II successful
system of refrigeration had not been
devised. When continuous hole
through the mountain has been made,
the temperature can more easily be
kept down. Two-thlrds OF the work
was completed last July, and the great
est obstacles have now been overcome.
