Handle of the Regulator to you, by which means you stop 

 N° ( I . ) and force your Steam through N° 2. into the P N° 2. 

 until that Vessel has discharg'd its Air through the Clack R 

 N° 2. up the force Pipe. In the mean time, by the Steams 

 condensing in the Vessel P N° (1.) a Vacuum or Em|)tiness is 

 created. So that the Water must and will necessarily Rise 

 up through 7" the sucking Pipe, lifting up the Clack R N° (3.) 

 and tilling the Vessel P NM. 



In the mean time the Vessel P N° (2.) being Emptied of its 

 Air ; turn the Handle of the Regulator from you again, and 

 the Force is upon the Surface of the Water in P N" (1.) 

 ■which Surface being only heated by the Steam, it does 

 not condense it, but the Steam Gravitates or Presses with 

 an Elastic Quality like Air; still increasing its Elasticity 

 or Spring, till it Counterpoises, or rather Exceeds the 

 Weight of the Water ascending in S, the Forcing Pipe 

 Out of which the Water in P N° (1.) will be immediately 

 discharged when once gotten to the top, which takes up some 

 time to Recover that power ; which having once got, and 

 being in work, it is easie for afiy one that never saw the 

 Engine, after half an hours Experience, to keep a constant 

 Stream, running out the full Bore of the Pipe S. For on the 

 out-side of the Vessel P N° (1\ you may see how the Water 

 goes out, as well as if the Vessel were Transparent. For as 

 far as the Steam continues within the Vessel, so far is the 

 Vessel dry without, and so very hot, as scarce to endure the 

 least touch of the Rand. But as far as the Water is, the 

 said Vessel will be cold and wet, where any Water has fain 

 on it ; which cold and moisture vatiishes as fast as the Steam, 

 in its Descent, takes place of the Water. But if yo\x force all 

 the Water out, the Steam, or a small part thereof, going 

 through P N" (1 .) will rattle the Clack, so as to give sufficient 

 notice to ptdl the Handle of the Regulator to you ; which at 

 the same time begins to force out the Water from P N° (2.) 

 without the least alteration of the Stream ; only some times 

 the Stream of Water will be somewhat stronger than before. 

 If you pull the Handle of the Regulator, before any con- 

 siderable quantity of Steam be gone up the Clack R N° (1.) 

 But it is much better to let none of the Steam go off, (for
