ASSAYS OF LEADVIlLE OEES. 



621 



Assays of various ores The assays of the first division of the following table were 

 made by the writer in June, 1880, for one of the smelters. The silver assays present 

 a certain interest, since they were made in crucibles, whereas the ordinary method of 

 silver assay at Leadrille is that by scorification ; the lead assays, however, are the 

 ordinary fire assays usually made in the region. 



The assays given in the rest of the table were made by the different assayers 

 attached to the respective smelting works.
