208 ELECTRICAL RESISTANCE OF ACETIC ACID. 



3. The resistance in the solid phase above the eutectic 

 point is found to vary in a peculiar manner, as the temperature 

 changes. This variation has been explained. 



4. The effect of small quantities of water on the 

 resistance of the acid has been investigated and explained 

 and it has been shown that the conductivity of the acid in 

 the solid state above the eutectic point, is due almost 

 entirely, to the presence of this water. 



5. The temperature coefficient in the liquid phase was 

 found to be nearly constant and equal to 0.04. In the solid 

 phase it varies from 0.30 @ -43C to 0.25 @ -70C. 



In conclusion I wish to thank Dr. Bronson for the in- 

 spiration and help which made this work possible.
