 (Alcohol when rectified is not a conductor). 

 From his comparative experiments upon these liquida^ 

 lie draws the following conclusion : 



The oxidating liquid first in the order has the greatest 

 chemical power, and determines ihe oxygen pole with the 

 most of the solid conductors. The liquid of an inferior 

 rank is therefore a simple conductor only, which in the ap- 

 paratus for the dt.Gomposition of water indicates the hydro- 

 gen pole. The oxidating or irritating liquid, and the liquid 

 conductor, must therefore be distinguished from each other. 

 He observes, nevertheless, that the order he has assigned to 

 these liquids is not constant, unless we employ ihem at an 

 equal degree of concentration. 



The author afterwards examines the action which these 

 liquids exercise upon the various solid conductors which he 



regards
