and examine the goodnefle of the Ore in fmall quantities? 
7 f • Whether^ when the work in great , they ufe to melt the 
Ore withany Fhix or additaments, or onely by the force of 
the Fire 5 or in anyway between both? (as throwing in of 
Charcoals when they melt Iron-ftone does not only lerve to 
feed the FirCj'*' but perhaps by the Alchaly oi its Aflies to pro- 
mote the fufior: Lime.ftonej e?^. 
72, What kifid of Furnaces they ufe , to melt the Ore in ; 
whether they be all of one fort and bignefs^ or of differing ? 
73v What are, the Situation, Materials^ Dimenfions^ Shape, 
Bignefsj and in fliortj what is the whole Structure and Contri- 
vance of the Furnace If there beany thing peculiar and re- 
markable ? What Tools are ufed in fmelting, their Figures,ufe, 
and the whole manner of working ? 
74. What kindsof Fewel,and what quantities of it, are wont 
to be employed in the Furnace, within the compafs of a day , 
^ or week ? ^ow much is put in at a time ? Hfow often it is re- 
newed ? and how much Ore in a determinate time, as a weekj 
or a day^ is wont to be reduced to metal ? 
7 5". In cafe an Additame'nt be empioyedj what that is,and in 
: what proportion it is added ? Whether it be mingled with the 
Ore, before that be put into the Fire^or caft in afterwards^ and 
if fo, at what time, ^e. 
78* Whether the Ore be meked by a Wind, excited by the 
Fireitfelf; as in Wind-ovens ? Or by the courfe of waters? 
Or acuated by the blaft of Bellov.'s ; and if fo , whether thefe 
Bellows be mov'd by a Wheel, turned by water running under 
it, or falling on it > And what are , the Dimenfions, Situation, 
^c. of the Bellows? 
79. What contrivance they have to kt or take out the Me- 
tal^ that is infufion, andcafl it into Bars, Sews, Pigs^C^r. 
So* What Clay^ Sand, or Mould they let it run or pour it 
through ? And after what manner they refrigerate it / ^ 
81. Whether or no they do^ either to facilitate the fufion 
or to obtain the more ©r better metal, mingle differing forts 
or degrees of Ore of the fame Metal ? As in fome places 'tis 
ufualjto mingle poor and rich Ore;and at Mendip they mix two 
or more of thofe differing kinds of Lead-ore that they call 
Frim-Qre^ Steel.or^, Potern-ore^ ^c. 8 2.V Vhe>
