and eee inches wide, with a ledge round its perforation 
in the middle, rifing, as is already faid, from the i inner fide 
of the neck, of about half. an inch high, by’ which a gutter 
.was formed to colle¢t «the Boadentod’ Cane as it fell down; 
and from this there was a hole in the pan to let it run of 
by; to which hole they occafionally luted on a fmall hollow 
bamboo, of about two feet and a half in length, to convey it 
to the receiver below. The upper pan had Ala another hole 
In it, of about an inch fquare, at near a quarter of its cir- 
cumference from the one below juft {poken of, that ferved to 
Jet off the water employed in cooling; as fhall be mentioned 
prefently. 
_ Their adkur being thus fitted to the jar, they completed 
the alembic by taking a copper pot, fuch as we ufe in our 
kitchens, of about five inches deep, eight wide at the mouth, 
and ten at the bottom, which was rather flattith; and turn- 
ing its mouth downward, over the opening in the adkur, 
luted it down on the infide of the jar with clay. 
For their cooler they raifed a feat, clofe upon, and at the 
back part of the futnace, about a foot higher than the bottom 
of the copper pot. On this they placed a two or three gallon 
pot, with a round hcle, of about half an inch, in the fide of its 
and to this hole, before they lighted their fire, they luted on 
a fhort tube of a hke bore; pace the pot, and direéting its 
fpout, fo as that, when filled with water, it threw a conftant 
and uniform fiream of it from about a foot high, or near the 
centre of the bottom of the copper pot, where it was diffufed, 
pretty porep ctely. over its whole furface; and the water 
falling down into the upper part of the pan of the adkur, it 
thence was conveyed, through the fquare hole already men- 
tioned, by a trough luted on to it for that purpofe, to a cool- 
ing teceiver a few feet from the furnace; from which they 
took it up again, to fupply the upper pot as occafion required. 
As their ftock of water, however, in this fort of circula- 
tion, was much {maller than it feemingly ought to have been, 
being fearcely more than fix or eight gallons, it too foon be- 
came hot; yet, in f{pite of this difadvantage, that fo eafily
