lessens friction. ” As the ivintea devaleed tes the friction at 
the Siva is increased. The shaft is enabled, therefore, to attain 
on which it i 
working on an inclined plane of greater angle, and the ring is 
consequently urged round more rapidly. 
** The shaft neh ave rted by pivots in its hollow ends, in- 
stead of in the r just described, does not alter the case at 
all, except to plese ‘the direction of the ring. The friction of 
the shaft on the pivot transfers its ; weight from the top of the pivot 
to the side of it, and thus — clined ees is found, and i is 
urged forward as in the other c 
ss motion of the ring ; vik the outer end of the 
shaft rises above the plane of the horizon; ‘if it be retarded, the 
end of the shaft sinks below it. 
“ By observation, it will be seen that, in accelerating the m 
tion of the ring, the pivot at the outer end of the shaft is Greed 
against that side of the shaft which is Meta upward, and it 
immediately brings the pivot above the horiz If the ring be 
retarded, the pivot is pressed against the cipptii side’ of the shaft 
which is whirling downwards, and the result is that it immedi- 
ately sinks. 
‘When a counterpoise is placed on the opposite Pi the 
vertical rod from the ring, and the latter is lowered considerably 
_ below the horizon, the revolutions of the ring are date t in an op- 
posite direction. This result will not take place if the wheel be 
running at a very high speed. When it loses its rapidity, the 
friction at the lower pivot is much increased. The socket is 
4 1 upon it by the weight of the wheel, and the same direc- 
motion is imparted to the ring which the _ intel bas,
