AND SILVERING. 63 which is dissolved by the sohition in proportion assilver is deposited on the daguerreotype plate. Avery pure coating of silver is thus given to a platefrom which the best pictures are obtained.^^ This fig. shows the porous cell belonging tothe battery when used as a Groves.… … This may be used where a very large surface is to bedeposited upon. The figure is intended to illustratechiefly the deposition of alloys by the galvanic cur-rent. If two metals are contained in a solution, thegeneral law is, that the one most easily reduced bythe electrical process will be…
