multiplication of the found values by mnt 1 20; 
The found pressure which will lie in the neighbourhood of the 
point #7 in fig. 1, amounts therefore to — 3800 x 41,20 = — 156600 
atm., from which appears how enormous the distance is of the points 
D and F at such low temperatures. (At higher temperatures both 
the term — 76,08 in the equation for 8 and the factor 36 in the 
equation for p will become considerably higher). 
In a similar way as above we can now calculate for
