Gold chloride examined with platinum electrodes shows a good number of 

 lines, and with silver electrodes some lines coincident with platinum lines are 

 revealed. The solution lines are not very persistent, no lines appearing with 

 '01% of metal in solution. The lines showing in a •!% solution are XA 4792*8, 

 43107, 3927-8, 3133-2, 3122-9, 2918-5, 2676-1, 2641-6, and 2201-4.
