If you have a mind to make liquor for bleaching linen clothj 
let your liquor in the reservoir be 5 or 6 degrees strong of the 
hydrometer glass by pearl or potash, and the rest of the process 
as before ; be sure to wash the reservoir very clean from lime, and 
be careful of your luting for fear of smell ; the head of the still 
and lid of the reservoir is luted with water as you see in the plan. 
If you make it for linen, have the opinion of some man conversant 
in bleaching ; if the glasses can be got, I will write the use of 
-them. (See the plate.) 
A The cap of the still, 
B The body of ditto, which, as you see, stands 7 or 8 inches 
above the surface. The cap is in the form of a hive, entirely hol- 
low, with the tundishes solddered, as you see, one for the use of 
charging the still with the vitriol, and the other takes off the inffam» 
mable air, which is C, then it enters the intermediate box, through 
which it passes through the pipe D, and enters the vessel by the 
reservoir, which is E. Tne pipe stands about 11 or 12 inches 
above the surface, 1 inch bore, but does not dip in the reservoir; 
it drops its strength in its reservoir, which the motion of the wheel 
circulates the body ; the wheel or windlass, is the letter F, which 
is only the handle and a boy continually turning it during the whole 
process ; xt, the wheel is in tills form, with the arms the full 
diameter of the vessel ; the intermediate box, as you see ; the 
pipes or tubes stand 1 2 inches at the top, I mean from the hori- 
zontal of the top of the vessel. The centrepipe, which is H, dips in 
the water which is in the intermediate box and has two nostrils 
which give air, although being under water ; the intermediate box 
has always 4 inches of water, which is put in every time the. still 
is charged, and has a cock at the bottom to empty it occasionally; 
there is also the consolidate vessel, which is G, it stands about 7 
inches high, but made fast to the top of the reservoir. The con- 
solidate vessel is as thus : it has a lid, and on the lid is made fast 
a pipe which dips in the water 1 inch ; the lid is taken off to put 
the lime-water in : also there is another pipe which stands about 
3 inches on the top,, and in that pipe fits a tube which dips in the 
pitcher as you see in the draught ; the lid of the consolidating ves- 
sel fits in a cavity the same as the cap of the still, and the cavity is 
filled with water to keep it staunch ; also there is a cock at the bot- 
tom of the reservoir to rack -off the liquor, and another at the bot- 
tom to cleanse it out. The letter K. is the vessel which the old lees 
are thrown into as before mentioned. As to the proportions of
