‘ Srr,—I have the honour to hand you herewith the result of my analysis of 
the piece of Australian Gold obtained from you a few days since, and would 
remark that it has been conducted with every care to ensure an accurate result. 
The processes adopted have been those resorted to at the Royal Mint; and from 
»revious assays made by myself on large quantities of Californian Gold sent 
from this, the results in England have so nearly tallied that I flatter myself the 
following will be found a very near approximation to the truth, if not exact.

But it must be remembered that the average is hardly likely to be so high, as 
many larger pieces, doubtless, contain more silver.

‘‘ N. B.—The piece of gold assayed was of poorer quality than the ordinary 
specimens | have seen from the Ophir diggings. ‘This analysis cannot there- 
fore be relied upon as a fair criterion of the commercial value of the gold 
obtained in that district.
