In the tables the values of the ratios have been put down, and they 

 will be seen to be fairly constant in each table: 



Table XVII contains readings for benzene at 5*4° ; the leak was 

 so slow in this case as to attract attention, and it was found that the 

 benzene was partially frozen ; hence the curve in fig. 8 is dotted to 

 show that the benzene was in a different state. 



The curve corresponding to Table XVI would come very close to 

 that corresponding to Table XIV, and is therefore omitted from 

 fig. 8. 



Carbon Disulphide. — Tables XIX — XXII give the readings and 

 ratios for carbon disulphide at different temperatures.
