R12 Value of Native Gold, éc. 
12. Five specimens which were experimented on separately, and the 
details of which will be given hereafter, were fused into a button. In 
their original state they weighed 365-1 grains; when the button came 
out of the crucible with the slag adhering to it the weight was 
365°185, this increase of 085 being due probably to the borax used as 
flux. The slag was removed, and the specimen then

Tf then this be reduced in the proportion of 17486: 17489, its specific

14, A quantity of Gold-dast, apparently very clean and weighing 
962 grains, was carefully examined, and iron-sand and quartz to the 
amount of 1 57 grains removed; the whole was then carefully experi- 
mented on, and the specific gravity determined: the Gold was then 
fused into a button, and the specific gravity again determined.
