Beam of the Balance, and at the fame Diftance from 
the Centre of its Motion C. 
On the Balance are two flopeing Gutters F, F, into 
which the Water alternately runs from the Gutter G, 
and fo gives Motion to the whole Work 5 fo that thefe 
lad- mentioned Gutters F, F, do the fame Service as an 
Over-fhot, or any other Water-wheel, and coft a 
great deal lefs, but give as even and regular a Mo- 
tion, as any Bendulum^ for meafuring of Time; 
for as foon as fo much Water runs into either of the 
afore-mentioned inclined Plains of the Gutters, fo 
that the Momentum of the Water exceeds the Fridion 
near the Centre of Motion C, the Gutter immediately 
moves down with a Velocity increaflng, till the Ba- 
lance meets with the Refiftance of the Wooden 
Springs H and H, and at the fame time raifes the 
oppofite JVater-BellowSyOX. that Bellows which is fixed 
under the oppofite Gutter. In the fame Moment 
again as the faid Gutter begins its Motion, being come 
down on the Spring, delivers all the Water it has 
received; at the very fame time the Water begins 
to run into th£ oppofite Gutter, which receives its 
Load of Water almoft as foon as the former is 
emptied ; fo that one of the Gutters does its EfFed, as 
foon as the other has done his, and this alternately 
one after another. 
Thefe flopeing Gutters on the Balance do therefore 
all the Service and EfFed which a Water-Wheel does 
in working the ordinary Bellows , and that by means 
of the Power which the Water applies to the Wheel 
of giving the ordinary Bellows their Motion, after the 
fame manner does the Water here impower the flope- 
ing Gutters to do the fame Work.
