Dr. Scukrrer has been able to continue his observations. 
If the highest point of the three-phase p7-line is taken as the

remarkable point, one finds the value 0,024 for a, from PK ae sz

a, above, viz. : 
dy =a, {fl + 1,1158 + 0,816 2} 
or 
2,022 = 1 + 1,1158 # + 0,816 2? 
would yield 0,627 for the value of v, and hence for « reekoned 
from the 2ud component, the value 0,373. 
But small differences in the data change « considerably.

Dr. Scurrrer carried up his observations. And that the value of z 
for the remarkable point lies higher, appears also from the value of

If the ratio of the critical temperatures of the components is below
