The impcrtsn. secret induced in ths most eAditsnt

of his discovery had beer subjected. His family
sought in ysn for Others TO do os;ice TO his memory
by prosecuting the subject. Bat could be found
courageous or credulous enough 20 undertake the
hazard Of testing the verify Of so dangerous an en-
tsrprse.
But the memory Of a fac. go remarkable as that
which he hsd demonstrated, hsppiy destined not
10 perish Another citizen OF Phlsdephis NJ. George
T. Parry, hearing of poor Loyds experiments, deter
ined to investigate the subject and repest tosm tor
himself. For some three years Mr.. Parry has been
patiently soirg over the whole field OF inquiry and
trial much of the time at great e1pense, and often
With great apparent dagger TO his life. He fret 6.san

became coated or lined with q substance which
chemical Analysis showed TO be q non-oonduotor OF
electricity ard identical with that which is found IN
ali boilers that have been kDg in ute. be argued
that IL boiler became lined with this nonconducung
msterisl. it was in reality huge Leyden jar, filed
with electricity and ripe for explosion, seeing tia cleo
trcty 10 freely generated by boiling water. He so-
cordlps applied the insulated conductor used by
Lloyd in.ertipg through the top of tue boiler, so a.
10 discharge the electricity into the atmosphere as rap
idly as il might be generated The boiler thus treated
was an old ore bsi been in use several yesrs, aud
was not deemed sss with sgreatsr pressure than 90
pounds il wss IL feet lorg by ~ in diameter. The
safety vslvs was weighted at 6S pounds, and the fire
surface was covered With water. He evsporatsd al
the water at the full pressure of % pounds and then,
imtatrg the example OF Lloyd, he continued the hre
until the bottom of the boiler became red hot through
out it's whole length. To verify this important f.ct,
he csled I'D i've men 10 witness it. BY al previous
rule. the boiler was now certain to explode. Ye. Mr..
Psny courageOusy pumped thirty gallons of cold water
into his red hot boiler. Yet nosxplosion followed and
the only harm done to the old boiler few leaks
a. come of tho rvets caused by the sudden expansion
| and contraction to which the metal had been sub
cted No regular engineer could be found with nerve
enough to ssss, at this trial. Mr.. Parry was CON-
PEELED TO go through the experiment alone.
The belief is universal thai ali steamboat or factory
boilers if tried by the simple test of pumping water
Ito them while red hot mo.t evitaby plode But
here two boilers TO which the dangerous test Of red
heat and cold wafer had been applied with TIE simple
addition Of electrical oonduc.or, and yet they es
capped tie fate which happens 10 all other bJiIers
without conductors. Ii the facts correctly repre-
.ensd to us they 20 far TO prove that Messrs Lloyd
snd Parry have discovered and perfected preventive
of misery ard death as gres. and prOvdent,l 50 the
discovery of vaccination. But Mr. Parry has not been
ratified with testing the fact that il is the esct-
city within boiler which causes ~ explosion. He
bss sought and is still seeing, TO discover from WA.
mysterious outside source proceeds tho fatal spark
which gnites the imprOcsd monster OF destruction.
Yet lie supposes that the inside noneoDdocting cost
ing or lining may contain hole issure and that
through this the positive electricity Of the boiler, seek
irg en- equilibrium by contact with the negative ont

Gus cloud 10 tie bolsr TO toe thundercloud of Sum-
day, waiting for the proper moment to let fly its
bolt with violence proportonse to the negative con-
oi.iop of whatever may receive the charge. His
