When this is accomplished,there is no difficulty in perceiving how, at everyrise of the piston, the water of the cistern willcome in by the valve n, and the water in the up-per part of the barrel will be driven through thevalve a; and, in every descent of the piston, thewater of the cistern will come into the bairel bythe valve/), and the water below the piston willbe driven through the valve m; and thus therewill be a continual influx into the barrel throughthe valve9 n and p, and a continual dischargealong the rising-pipe I, through the valves mand o. This machine is certainly equivalent to twoforcing-pnmps, although it has but one barreland one piston ; but it has no sort of superior
