6636. PERPETUAL MOTION, Friction and.—
The diminution of friction is certainly
one of the most desirable reformations in mechanics.
Could we get rid of it altogether we
should have perpetual motion. I was afraid
that using a fluid for a fulcrum, the pivot (for
so we may call them) must be of such a diameter
as to lose what had been gained. I
shall be glad to hear the event of any other
experiments you may make on this subject.—
