CuCl 2 in less than 460.28 liters gave A=5.22X10 -6 . A 
resistance of 6000 ohms was introduced in the measuring. 
ACETOPHENONE. 
A sample of acetophenone from Schuchardt was treated with 
barium oxide, over which it stood for several days and then dis¬ 
tilled. The distillate was redistilled and the portion coming 
over between 194° and 195° C. at 745 mm. pressure was taken. 
The specific conductivity of this portion was 1.8 X 10~ 7 .
