Through the favour of my colleague, Dr. Hodgkinson, I 

 obtained some pure iodide and bromide of ethyl. These were 

 again washed, dried, and redistilled. The following Table 

 shows the vapour-tensions of their mixtures. They were 

 shielded from the light when in contact with the mercury.

The curve F, fig. 7, shows that the vapour-tensions of the 

 mixtures of these two substances lie nearly in a straight line, 

 and that the two substances therefore very closely fulfil the 

 condition of absolute non-interference.
