pneumatic fabrication" II what
DIR. Carlo Del Iungo, OF Genoa, calls
his new plan for increasing the speed
or ships. II consists In reducing the
density OF the surrounding water by
pumping air into Il, creating foamy
stratum In which the vessel slips for
ward against greatly lessened resist
ance.
A Norwegian engineer has recently
invented a new apparatus for sea
sounding by which II is not necessary
to touch bottom. This Ia accomplished
by an acoustic method, The depths
are also registered graphically upon
revolving drum. The operation OF the
device depends upon the time which
sound takea 10 travel TO the bottom
and return. and the measurement OF
the time thus gives the depth 10 which
the exploring apparatus Is lowered.
A safety device for the protection OF
persons from the electric current upon
the rupture Of a trolley wire has been
invented recently. BY the employment
OF this arrangement the current IL cut
of and the wire rendered harmless.
| The device Ia fitted 20 each section OF
the wire and consists OF an ordinary
connecting cor held In its proper po-
sltlon by the strain on the trolley wire.
| As soon As this tension In released.
~ by the breaking OF the trolley
wire. the current Is Immediately cut
off at the broken section without any
"shortlng" sparks whatever.
Gales and high tides have remind
ed the Englishman that his little
island Is being gradually swallowed
up by the sea. II has been found
that Great Britain lost l4s,a06 acres
between 1867 and 1850, and 2o,ib5
acres between 1890 and 1890 A sur
vey in the reign OF Edward !. gave
the Duchy OF Cornwall 100000 acres,
but the Ordnance Survey some years
ago showed that this had been re-
duced to a3p,5O0 acres. Villages have
disappeared in the ocean. as In the
case OF DanwIch. OF which nothing
remains but a ruined church on tho
edge of a cliff.
DIR. Walther Thorner has invented
an apparatus by which photographs
may be made of the retina OF the
human eye. Heretofore, says the
Scientific American. II has been possl-
bile TO study the retlna and It's dis
eases only by direct observation with
the eye speculum. The fixed image
furnished by the Photographic appar-
atus enables the physician TO study
the condition OF a diseased retlna at
his leisure. Previous attempts to
J photograph the interior OF the eye are
! said to have failed because or tho
: difficulty OF securing proper illu'
mination without pain and injury to
the patient.
