Of the fecond parcel of Mtimcny , whei^^ith the firft 
Regulus of Gold and Antimony (si^ttighm^ 5 feny weight 
^\graim) was melted, there remained in CM i pe^y vesight 
^ grams ^ (^nj grams.} 
All the other parcels were fine Gold to fenfe , upon the 
Touch. Only that out of the firfi: Antimony ^vfdiS apparent- 
ly [unfine and pa!e, from the Silver in the original Alloy 
mixed with itj and not from any remainder of Antimony % 
as appeared by the ineonfiderable wafie upon meltitig in a 
great heat with a blaft upon it : And alfo by the Toughnefs 
and Malleability: and by comparing ir, on the Touch- 
ftone, with Sovereign-Gf)W allayed with Silver^ to v^hich it 
did agree, but wasfomewhat paler; holding, to the judg- 
ment of fenfe, 'about a fourth part of Si/z/er^ as theSove- 
Ttlgn-Gold doth a fixch. Neither was it altogether free 
from Copper ; becauftjUpon NeaIiDg,it always turned black 
on the furface. 
But for more exaft difcovery, it was taken and firft Re- 
fined with Lead upon a Copel, for reparation of any Cop= 
per that might be in it. Upon which operation, it came 
forth I feny weight 9^ grains CSSi g^^ins ) which was 
2X grains lefs than it was before. Afterwards this laft was 
melted with betwixt two and three parts of Silver^ and fo 
wrought in Aquafortis for feparation of the Silver: and 
there remained in Gold i feny weight^ /^^ grains (28^^^;?/) 
which was dve grains fhort of the former* And yet it ap- 
pearedjUpon the Touchy not fine, but paler than Vlue-Gold , 
and deeper than Crown -Gfj/^i allayed with Silver. So that 
what remained in it was neceflTarily of Silver h and it might 
be eftimated about 23 keratts fine ; or to hold in fine Gold 
zbout IT grains^ 
Whatlofs of Gold was upon this Refining with Anti" 
;w^wy,may eafily be computed. Firft, one twelfth is to be 
deduSed from the firft quantity of Crosvn-Gold^ being 
7 peny weight and 10 grains ^ ( lyS grdins ) for Alloy ; 
which is I ^grains and So the remainder is,6 peny weight, 
ingrains and | ^ or 163 ^^grains.
