The most beautiful experiment we ever Witness
ed WAS the bud sound and brilliant flash from the
galyanc spark, when produced near certain point
IN his great magnet Each snap was as loud az a
pistol and when he produced the same spark Al a
little distance from this point, il made no noise at
all This recent discovery he stated 10 have prac

maensaic engine. Truly. great power is here !;

He then exhibited his engine, Of between four
and i've horse power, operated by battery con-
aained within space Of three cubic feet Hiooked

The engine starred of magni6eently, making ia
strokes per minute though when ii drove circn-
lar saw zen inches IN diameter, saving up boaris
an inch and a quarter thick into aths, the engine
made but about sigh y strokes per minutes. There
was great anxiety on the part Of the spectators TO
ohlain specimens Of these lafhs, to preserve as iro-
pixies Of this great mechanical triumph The force
operating upon this magnetic cylinder ihroughouh
the whole mOtionof two feet was slated TO be 6u0
pounds when the engine was moving very slowly,
hut he had not been able to ascertain what the force
was when The engine was running al a working
V speed. though ii was considerably less. The most
important and interesting point, however, is he ex
psnae Of The power Professor Page stated th4t he
reduced The cost 50 far that it was less than steam
under many and most conditions, though not SO low
as the cheapest steam engines. WIthall the imper-
ieeions Of ihe engine, The consumption of three
pounds Of zinc per day would produce one horse
power The larger his engines CONTRARY 10 what
has been known beforei the greater the economy.
Professor Page was himself surprised at the result.
There were yet practical difficulties to be over
come; the batlery had yet 10 be improved; and it
remained yet to Try the experiment on a gralder
scale, 70 make power Of one hundred horse, or
more, a.
Truly the age is franght with wonders; and we
can now look forward with certainty to the lime

scald and destroy. s
