Bafe is Four Feet, with Holes round the Edge, for 
Nails or Screws to fallen a globular Head of Copper 
of about Five Feet and half Diameter, as by the Figure 
annext will appear [Tab. VI. Fig. 2]. There is then 
placed in thelnfide a fmall VelTel or Machine, which 
I call a Difperfer: This Bafon or VelTel hath Spouts 
round the Sides fixed to it, and the Bottom thereof 
refleth on a Centre-pin 5 and in the Middle of this 
Bafon or VelTel is a Socket, with Holes near the Bot- 
tom, to let the Water or Fluids pafs from above, 
through an iron Pipe of about Seven Feet long, the 
lower End of which is placed in the Socket, fo as the 
End of the Pipe will be always immerged in Water 
in the Bafon, to prevent the expanded Fluids from 
returning up the Pipe ; and the other End of this Pipe 
goes up through the Copper-head, which is inelofed 
very tight, but fo as it may eaftly be moved with a 
circular Motion, in order that the Water or other 
Fluid, which is conveyed through this iron Pipe 
down into the Difperfer, may be difperfed or fhowered 
round, on the Sides of the red-hot Pan, or ignitted 
VelTel, in a very exa & manner. 
This evaporating VelTel being thus completed, we 
then take One, Two, or more, of thefe Veflels, with 
thefe Contingencies, and place it or them in a rever- 
beratory Arch or Canal, for conveying the intenfe 
Heat of a ftrong Fire, the Flame of which encom- 
paffes the metal Pot or Pots, and brings them to a 
red Heat 3 and in that Condition they are continually 
kept, while in UTe, with the Water running from a 
Cittern or VelTel (where the Water is heated) through 
a Gauge-cock down the iron Pipe into the Difperfer, 
which conveys it to the Sides of the ignified VelTel or 
Pot,
