For a comparison we give the following results obtained with a 
Cailletet tube : 
critical end-point 81°,02 instead of 31°,03, 
1) By way of comparison with the preceding binary systems we have also carried 
out a few observations with this mixture. ; 
2) With this first filling the critical concentration was not quite reached; there 
was a little too much aniline, and it was clearly to be seen how the cyclohexane 
was dissolved in it. =
