LIGHTING Gas BY ELEcrRIciry.-Sanl. Gardiner,
r., Of New York, ps,ened in 1857 sn electric spPNa-
tus by means of which person sctiug on two keys
could light or shut off at viii, aud at tie same m'ment,
all the gas burners Of q building, or any designated
number OF them. II was sppled TO the lights If the
Broadway Thea.er, and was made 10 work several
times every evening to the grea: amusement OF the au-
derce. The stopcock of every chandelier and osevery
isolated burner is provided with rachel wheel winch
is acted upon by catch contested with an ordinary
electro magnet, and ca ,h msgnet ia connected by
wire with a battery and with a clrcui,-breakng key
placed in the operator room. Over every burner IL a
coil Of fine plana wire, and al these coils connected
together by copper wires in the Great o. another
electric current which may be closed or opened by
means of another breaking key. To light the
gas the operator closes the circuit OF the coils OF pa
tina these become red-hot. lie then closes and opens
the topcocks circui, many times as necessary TO
make the ratchet wheels describe quarter Of c'cle
The stop-cocks then opened and the gas rushing
Oh the burning coils is lighted The burners are
turned eff by playing again on the key til the rachel
wheels have moved another quarter OF circle, then
the .top.cocks closed. BY having many keys as
there are burners or groups Of burners each burner or
each group may be operated separately from the 9TH
ere. BY throwing ali in circuit, they may be ope-
rated with single key. The of this nyentii does
away with the Of fire consequent upon the use

cessary expense of gasn large establishments where the
lig ting has TO be begun one hour before light wsned

been psterted, March, 1853 by the original inventor.

cheapest metal which does neither melt burn under
tie circumstances described. The apparatus tnus n
proved has been lately applied to the 500 burners OF
the Senate Chamber 10 Washington and is said TO give
complete satisfaction.
INV MUSICAL INsrRuMENT.-The successful et-
torts of art-mechanics in music have for long time
been exclusively shown in improving the old instru-
mtnts of past centuries but not in adding instru
ments Of high value and rank to the st. We have at
last tly examined instrument, made by Aessr'
Hill which /. essentially Dovtl, and, makirg every a.
lowa1ce for the inevitable DEFICIENCIES of first out
worked attempt of the principle involved, the result If
promising ard brilliant. The inventors call it, stupidity
erougb keyed harp whereas its qualities are pre-
cisey those which the harp has not, namely, sus-
tanned sound. II lie played upon Ike the piano forte,
and while the tone stroke has not the readiness or
crifpnees or vitality Of that instrument the sustained
vibration s much greater when not arrested by me-
chaLical meaDs. The note caDnot be shaded after
once ded but the continuation OF the vioraon we
are sssured by the inventors, can under tho extended
spplca,iop of eecond and improved manufacture be
secured for Whole minute. The Instrument, We heard,
wants power, which the inventors say can be more
than doubled BY doubling the size Of the constituents
