340 Messrs. Wright and Eennie on the Determination of 



tween voltameter-plates (commencing with 237*5 and slowly- 

 sinking to 231-0) =232-40. 



Average potential-difference in volts, 



232-40 



80-60 



x 1-457 = 4-201. 



Hence, taking a = 8-98, ^=0*000105, and J=42xl0 6 , the 

 value of e in the expression 



n 



becomes l'540xl0 8 ? since E = 4-201xl0 8 , A=3338, and 

 n = 0-4967.
