M. FRAscHor addressed to the Academy upon the
subject His idea to proong indefinitely, by
Of clockwor the vibrations Of the pendulum used in the
experiment Of NJ Foucau The published minutes Of the
proceedings Of the Academy do not describe the mechanism
which would be difficult TO- understand without the aid Of
diagrams Suffice it to say, that clockw is contained
in the interior Of the sphere Of the pendulum and thus the
apparatus having in certain respects the appearance Of PEN
duIum Breque differs from in the essential part cuar that
il receives impulse absolutely independent Of the direction
of the frat oscillation. When this read M FAYE
remarked HAT NJ Fanchos noion Of ectng, by means Of
internal clock-wor periodical dpscsmsns Of the centre Of
gravity, and thus prolongng the oscillations Of the pendulum

At the sitting Of the Academy Of Sciences on last Monday
M MoRIs Director Of the Conservatory Of Arts and Trades
Paris read paper intended to prove that the invention Of
he steam locomotive also belongs to this country, being due
to an engineer named Cugnot His locomotive destined for
ordinary roads, was constructed in l770 and deposited ut the
Conservatory in 1901 The machine intended to
vey four PERSONS and moved the Of x miles per hour.
Trials had 10 presence Of the Duke Of Choseu and the
then Minister Of War; which 30 much satisfacion tina

tobe built Sasboug. The machine in fact construct
