Summary 



The temperature-composition diagram for the system methane- 

 nitrogen at atmospheric pressure has been worked out and the con- 

 stants in the formula — 



log / = a+b log r 

 determined. 



It may be added in conclusion that though exceptional accuracy 

 is not claimed for these results yet it is believed that they are fairly 

 correct.
