Of the KdgW^ a piece was broken off, which weighed 
1 fep^y weight 14 graitts and an half (38^^^^//^/, ) and was 
kept to be refined upon the Copel apart. The weight of 
the Remainder was therefore Sf ^^y weight \ grains ^w6i^n 
halfCi24U^^^*»^0 2 A ^ 
This Remainder being powder'd and put upon equal 
quantity of frelli Jntimotiy^ as at firft, (/>• two ounces and 
a quarter) and melted down , the Regulm weighed 3 feny ^ 
weight znA 7 gTAins, (.7 ^grains). 
The other Piece ©f i peny weight 14 grains and half, be- 
ing refined oa a Copel from the Antimonial fubftance mix- 
ed with it (by exhalation, promoted fometimc wicha blaft 
uponir, cfpecially toward the latter end, as in all the fol- 
lowing Experiments of Refining upon the Copel j weighed 
1 feny weight (> grains and half (30^ grains:) and upon 
melting with B^rax in a Crucible, loft not above half a 
grain. So that the weight of the whole to the Gold it held, 
was as jSi to 3©^, or the Gold almoft ^ of the whole. 
The latter R^^W^ weighing 3 fenj weight ^nd 2 grains^ 
(t»e. -j/^ grains) being Refined in the fame manner, weighed 
2 feny weight and grains^ {i.e^ 63 grains:) the GM 
holding proportion to-the whole, as 63 to 74, that is near 
uponf of the whole* So that the fame Regulus of G$ld 
diiid Antimony, in paffing through new Antimony^ though it 
lofe much in weight, yet there is not a proportionable lofs 
of Gold: but is richer in Gold, as is proved by this and 
many other Trials,- and fo appears to fenfe, being of a 
redder complexion, more tough and hardier to pow-

mixed with equal weight both of Tartar and Wf>r^*, and 
then fired, and fo reduced to a Rigulus. Then the Eegulm

parcel of Antimony, wherewith the Gold was firft melted, 
the Regulus being exhaled, there remained in Gold i feny
