 We found : 



(ft^)^ = 938,2 ; «'=1: 15,562:= 0,06426. (a^z= 368,6) 



When a' . RT= y is put, we can easily calculate ƒ '(T) = (6^.y — l):y 

 at higher temperatures from f'{T) = J + Va y + Vo .v' + • ■ • 



In table II the values of a, b,,, and B are put together, which 

 can be calculated from the thus found values oï f{T), f'{T) and 



^/'^B — 1 from (13) and (14). The last column but one gives the 

 values of B which would follow from K. Onnp:s' and Amagat's 

 experiments. 



With regard to the value of 10^ B at 0° C. we may state that 

 it is clear that it will in any case lie in the neighbourhood of 590
