i50 Mr. G. Gore on the Electrical Relations of 



Molybdic Acid. — Copper, silver, platinum, carbon. Silver and 

 copper acted upon. 



Bichromate of Potash. — Silver, copper, silicium, carbon, iron, 

 platinum, gold. Reversal with copper and silver. 



Chromate of Soda. — Iron, copper, carbon, silver, platinum, 

 gold. Currents strong. 



Chloride of Manganese. — Copper, silver, iron, carbon, gold, 

 platinum. Currents strong. 



Bisulphide of Arsenic. — Silver, iron, carbon. Silver dissolved 

 rapidly. 



Ter sulphide of Arsenic. — Copper, iron, platinum. 



Teriodide of Arsenic. — Silver positive to platinum. Bad con- 

 ductor. 



Arsenite of Soda. — Iron, silicium, carbon — silver, copper, pla- 

 tinum. Reversals with silver and carbon. Iron, silicium, and 

 carbon evolved much gas. Platinum, copper, and silver rapidly 

 melted in it. 



Teroxide of Antimony. — Silicium, iron, carbon, copper — silver, 

 platinum. Reversal with silver and copper. 



Tersulphide of Antimony. — Silver, copper, zinc, iron, silicium, 

 platinum, carbon. Reversals with platinum and iron, copper 

 and silver. Copper and silver dissolved quickly. 



Teriodide of Antimony. — Silver, zinc, copper, iron, carbon, 

 platinum. Currents feeble. 



Terbromide of Antimony. — Copper, silver, zinc, iron, platinum, 

 carbon. Reversal with zinc and iron. Currents very feeble. 



Oxyhromide of Antimony. — Silicium, iron, copper, silver, car- 

 bon, platinum, gold. Silver and copper dissolved quickly. 



Fluoride of Antimony. — Zinc, iron, copper, silver, carbon, pla- 

 tinum. Iron coated itself black. 



Bromide of Zinc. — Copper, iron, silver, platinum. 



Chloride of Cadmium. — Aluminium, zinc, iron, copper, silver, 

 platinum. Reversal with silver and copper. Zinc melted quickly ; 

 aluminium similar, with violent action. 



Mineral Phosphate of Lead. — Iron positive to carbon. Iron 

 dissolved with strong action ; gas also evolved from carbon. 

 Much lead reduced to a metallic button. 



Iodide of Lead. — Zinc, silver, copper, iron, platinum. Rever- 

 sals with platinum and iron, silver and zinc. Copper and silver 

 dissolved rapidly. 



Chloride of Lead. — Zinc, lead, copper, iron, silver, platinum. 

 Reversals with copper and silver, copper and iron. 



Chromate of Lead. — Carbon positive to iron. Strong action 

 and intense heat at surface of iron. Iron much dissolved; car- 

 bon also corroded.
