of copper tinned, or of iron, which fapplies them 
with hot water for their tea. This water evaporates 
in the night, moiftens the air of the room, and ab- 
forbs the noxious particles of the fea coal. We 
cannot forbear dwelling upon thefe little ceconomi- 
cai obfervations, as our aim is public utility. The 
Chinefe are wont to fay. The Emperor can build a 
palace, and cannot make a flirub ; one word from 
his mouth makes a nobleman of a mere citizen, but 
ail his wifhes and prayers cannot prolong the lives 
of his favourites one iingle moment. 
It is not our part to point out what ufe might be 
made of the Chinefe Kang beyond the feas j but we 
apprehend that the Ti-Kang might be a profitable 
improvement for hofpitals, manufactories, &c. and 
a pleafing one for the rich. The To?ig~Kang pro- 
perly managed would do very well in upper rooms, 
and would afford warmth for the bed-chamber, and 
fire for the drefling-room. The Kao-Kang feems 
lefs adapted to the cuftoms and manners of Europe, 
but induflry might find fome ufe for it in the coun- 
try. Should the Kang be rejected on account of 
its novelty, fome hints might ftill be taken from 
its conftruCtion for the ufe ot feveral kinds of handi- 
craft. 
The Chinefe fea coal may give fome infight into 
the formation, qualities, ufes, and nature of this fingu- 
ra! folhl; but this would require a feparate paper. 
All we fliall here obferve is, that, as far as we can, 
judge from the famples we have feen, it feems for 
the moft part to be a ftone diffolved by the waters, 
and impregnated with fulphur. Its hurtful qualities 
proceed from a mixture of antimony, copper, iron,
