cool it, there ran a ftream of liquor from the. ftill, and but 
very little vapour rifing from it, beyond any thing I had ever 
feen from ftills of a much larger fize, fitted ‘with a worm and 
cooler. In about three Lone time, indeed, from their light- 
ing of the fire, they drew off full gree bottles of tpinit; 
which is more by a great deal, I believe, than could have 
been done in our way from a {till of twice the dimenfions. 
The conveniences of a worm and cooler, which are no 
{mall expence either, I have myfelf often experienced; and 
if thefe could be avoided in fo fimple a way that might eafily 
be improved, the hints that are here offered may be of fome 
ufe. The thin metal head is certainly well adapted, I think, 
to tranfmit the heat to the water, which is conftantly re- 
new ed; and which, if cold, as it ought to be, muft abforb 
the faftett poflible: whereas, in our way, the water being 
confined in a tub, that, from the nature of its porous fub- 
ftance, in a great degree, rather retains than lets the heats 
pafs away, it foon accumulates in it, and becomes very hot ; 
and, though renewed pretty often, never anfwers the purpofe 
of cooling the vapour in the worm fo expeditioufly and ef- 
feftually as is done by their more fimple and lefs expenfive 
apparatus. In this country, more efpecially, where labour 
and earthen-wares are fo cheap, for as many rupees, and 
lefs, twenty furnaces, with ftills, and every thing belonging 
to them, independent of the copper pots, might very well 
be erected, that would yicld above a hundred gallons of {pi- 
rits a-day; allowing each flill to be worked only twice. So. 
very cheap indeed is arrack here, to the great comfort of my 
miners, and of many thoughtlefs people befide, that for one 
fingle peyfw (not two farthings fterling) they can get a whole 
cutcha-[ecr of it in the ba/ar, or above a full Englifh pint, 
and enough to make them completely intoxicated ; objects 
often cantal to be feen. 
Of the fuperior excellence of metal in giving out heat from 
itfelf, and from: vapour contained in it, we have a very clear 
proof in what is daily performed on the cylinder of the fteam- 
engine : for, cold water bemg thrown on it when loaded, the 
containcd vapour is conftantly condenfed; whence, on a 
vacuum being thus formed, and the weight of the atmo-
