ese cases, are obviously due to the absolute contact at once es- 
tablished with the iron surfaces by the magnetic quicksilver, and 
the perfect and powerful voltaic circuits thus kept up constantly 
throughout the two metals and the solution.

VIII.— Applications to the Mercurializing of Metallic Surfaces in general. 
In all cases in which it is an object to save time and labor in 
the coating of surfaces of other metals with quicksilver, * * * 
the magnetic amalgams come into play; * * * 
By virtue of the adhesion to iron and other non-amalgamable 
metals imparted by the magnetic amalgams, I am enabled to 
apply quicksilver, or fluid or pasty amalgams, to any metallic 
surface, with great rapidity and facility, with a brush, after the 
fashion of a paint; the material of such brush being fine wire of 
iron, steel, aluminum, or platinum. Of these the material most 
generally suitable is the finest steel wire, tempered to about a 
spring temper, or somewhat softer; and the most generally use- 
ful ge for such brushes, is that of a flat varnish or white-wash 
rush, 
Separation of metals from ores, and of granulated or floured 
quicksilver from ores and slimes, etc.
