12th. In all cases in which mf@tallic surfaces, such as copper 
plates, the zincs of voltaic batteries, etc., are to be amalgamated ; 
the use of quicksilver combined with sodium, or other highly 
electro-positive metal; as above set forth. 
th. The more rapid and convenient application of quicksil- 
ver to surfaces with metallic brushes; by virtue of its previous 
combination with sodium, or other highly electro-positive metal ; 
as above set forth. 
4th. The use of metallic brushes, enfilmed with an amalgam 
of sodium or its equivalent; for incorporating together particles 
of quicksilver, gold, silver, or any other metal, scattered through- 
out ores, slimes, or any other materials; as above set forth. 
_15th. The more convenient transportation, handling and sub- 
division of quicksilver; by conversion into solid forms; in the 
manner herein substantially described. 
pre 
in a 
aid of sodium amalgam 83°3 per cent were recovered. The re- 
Sults in the large way in actual practice would probably be 
More satisfactory than those last named. Prof. S. stated that 
experiments had also been set on foot in California to test this 
rocess on a large scale in the actual working of quartz mills. 
The results of these experiments will be noticed hereafter. =
