RATORs.
Scientific circles have lately been amused and
interested by IAN exposure" OF an nyentioniby Mr H.
Paine OF "waergas notoriety," of an electric engine
which attracted some attention year ago. An enthu-
siastio editorial in The Journal Of Tee0raphy on the
'new electromotor," created much excitement during
last Spring. and the article was extensively copied IL
predicted the dawn of new era in the mechanical
world Mr. Paine asserted that his engine, whicD was
put in operation Newark, N. j. developed two-horse
power by the Of his peculiar electromagnetic bat
terry and further, that any desired degree OF power
could be obtained simply by multiplying the number OF
the magnets.
Mr.. PaiDes claims and propositions admitted ana
he obtained financial aid from gentlemen familiar with
practical inventions OF this class patents were as
signed to joint stock company, with capital OF three
millions OF dollars, called the "Paine Electro Magnetic
Engine Company" lie is now busy at Newark building
horsepower machine. As yet The Journal Of Tete
grdphys the only scientific periodcathat gives their en-
terprise any Endorsement The Scientific American treats
the whole matter joke.
general impression among scientific men is that this
machine is really by belt from steam engine in

Mr. Paine, who began'showng the small model machines
apparently with no power, as they could be stopped
without effort The visitor becoming critical, Mr.. Paine
undertook to convert him by showing me machine itself
The wheel TO which the magnets were attached was
unlike the models, ncosed in castiron case, which en-
veloped it closely above, but spread out into recangu-
lar base below. The laher rested directly on the Goor
belt connected the machine with small circular saw

greatest To show the excess of power they were
sometimes placed on edge and passed over the saw

end without the velocity being at all diminished. On
throwing off the belt from the saw, the machine still
proceeded the same velocity with entire indifference
to external resistance On mentioning this to MI Paine
he informed me that when the saw was attached and
the resistance greater the increased pull on the magnets
brought them together, by bending the heavy
iron frame and, magnetic attraction varies inversey
as the square Of the distance, 1t only required small
change of distance account for the increased power
The visitor canddly told the inventor that he be-
leved that the steam engine which he heard moving in

whereupon Mr. Paine threatened TO throw him out of the
window. He up as follows;
