 some electro-chemical phenomena, by Mr. Brande, was read. The 

 identity of Voltaic and common electricity was first shown in 1801, 

 by Dr. Wollaston. The object of the present lecture was to point 

 out various other instances in which common electricity exhibits the

 are exposed to the action of the Voltaic battery, oxygen and acids 

 are attracted by the positive end ; and alkalies, metals, and coai- 

 bustibles, by the negative end of the battery. Mr. Cuthbertson 

 found that when the flame of a candle was placed between two 

 excited balls, the negative ball was much more heated than the
