238 ANALYSES OF METALLIC IMPLEMENTS. 
sulphocyanide was filtered off upon asbestos in a perforated crucible provided with 
a subsidiary perforated disk (Gooch, Am. Jour. Sci., xx, 11 [1905]) to facilitate the 
removal of material from the filter. 
No attempt was made totransfer all the precipitate to the filter, but the contain- 
ing beaker and adherent material with the precipitate upon the filter were washed 
twice. The filtrate was reserved for treatment. The crucible was placed inside 
the beaker, the disk with the adherent precipitate removed and placed outside 
the crucible within the beaker, the beaker was covered with a watch-glass, and the 
cuprous sulphocyanide adhering to beaker, crucible, and disk was treated with 
a mixture of sulphuric acid and nitric acid. Water was added after complete 
solution of the precipitate had taken place. ‘The solution was filtered from the 
asbestos and evaporated to the fuming-point of the sulphuric acid, neutralized 
with ammonium hydroxide, acidified with a few drops of sulphuric acid, and elec- 
trolyzed with the use of the rotary cathode. (Gooch and Medway, Am. Jour. Sci., 
Xv, 320[1903].) The deposit of copper was weighed.
