There was also 0'061 part of silver present in 1000 parts of the 

 mass, the remainder being base alloy. 



Another set of assays from the same ingot, but from the opposite 

 end, at the point marked B, gave the following results : 



1 429-9 



2 459-5 



3 439-0 



4 . 429-0 Silver . 0'071 



Average 439'35 



The difference in the amount of gold between the two opposite 

 ends of the ingot was, therefore, no less than 223*10 parts in 1000. 

 The base metal present was proved by analysis to be chiefly zinc, 

 Jead, and copper, as the following results will show on metal taken 

 by a " dip," i.e., from the molten metal : 



Zinc 15-0 



Lead 7'0 



Copper 6'5 



Iron 2-2 



Mckel 2-0 



Silver 7'0 



Gold (by difference) 60%3 



100-0 



B. Another ingot of alloyed gold weighing 12 223 kilograms gave 

 at different parts of the ingot the following results by assay : 



Four assays on a piece of metal cut at a top of ingot 



Gold. Silver. 



1 664-0 0-090 



2 662-5 0091 



3 465-0 0-076 



4 . 661-5 0-091
