with iron pyrites I got all the copper out and much of the silver. By a second fusion I got a large bead of gold of almost exactly the composition of the sequins but I did not get a good clear red colour on heating it after beating it out flat.

The results of the analysis of these two samples are:-

1st fusion
very small sample

Gold 88.6
Silver 9.5
Iron 0.1
-----------
98.2

2nd fusion

97.77
1.41
0.82
-------
100.00

Sequin

96.37
2.77
.85
------
99.99

no copper in any of them after the first fusion with the pyrites.

Are you in London at present and if so, how long are you going to be here?

Kindest regards from us both,

Yours very truly,

Alexander Scott
