the Second Experiment cf repeating tht Opemmi^, : '^ 
fame Antimony. 
There was taken of Crown«G(?W to the weight of ^ penf 
weight 21^ grains. Which was meited with ope ^MW3it:a^;d 
(about a fixfold proportion 3 of Antimmy. Tht Kegulus 
weighed s pen/ weight ^ud ^gr. 
From this, a piece weighing i peny wight and 6 grains^ 
broken ofr and referved for re&ning by it felf 5 the re- 
mainder, being 3 peny weight and 21 grains ^ was melted 
down again With the fsimG Antimony ^ being powdered and 
put on the top: and thereupon the Regulud came forth, 
weighing 3 /'^/y' w^^gA/ and ingrains: fo that here was no 
confiderablelofs. And there is ground to fufpefi, that it 
might be upon feme accidental difference in <he managing, 
that the Regnlus did not fo perfeftly feparate and fettle; 
For in all other Experiments of melting the fame ReguJus 
again with the fame Antimony ^ the Regulu^ gained weight ; 
as in the next follpwing. 
From this Cecond Regulus^ a piece broken off and re- 
ferved for refining aparc^ weighing i peny weight dind 12 gr^ 
the remainder being 2 peny weight 7 grains ^ was melted 
down, as the former, and in the fame Antimony. Whereupon 
lYitRegulm came forth in weight 3 peny weighty \i grains 
being here gained to grains^ making the whole "j 2 grains^ 
i.e. between \ and i. 
The firft piece of i peny weight dsxd 6 grains ^ being re- 
fined upon the Copel, produced of FinG-Coid i p, weight 
juft : which holds in proportion as 24 to 30. So that it 
contained four fifths of Gold^ and but one fifth of Antimonial 
fubftance in it. 
The fecond pieca vveigbing L/?. «?. and !?2^r. being re- 
fined upon the Copel, produced of fine Gold i p.w. and 4^r. 
iu proportion of 28 1036, which is rather lefs than four 
fifths, as in the former ^ but the difference is inconfiderable 
for quantity.
