Fig. 3. 



Curves plotted for benzene from Tables II and TV. 



The straight lines through the ratio curves are drawn to show the mean value of 

 the ratios. 



In the ratio curves 1 division of the ruled paper corresponds with O'Ol in the ratio- 

 values. 



In the deflection curves 1 division = 20 in the deflection.
