The /5-valiie in the viiponr begins to be smaller here than that 

 in the liquid ! 



<L / = -_140^20 = 132,89 abs. Hence m — 0,8821 , 3,424 y/?=3,020. 

 For j) we find through linear interpolation yi; = 22,795, f = 0,4749;

The value of /?„ is 0,41 ; 0,20 remains far below this. We moreover 

 point out that also h of § 17 at t r= — 149°,6 yielded a perfectly 

 hai-monious value for the vapour, viz. 0,19. The two series of 

 observations, tlierefore, cover each other entirely.

/?,, begins to be more and more impossible. We point out that 

 when /'- 1 is taken not =5, but e.g. =4,95. the value 

 Bi;,j, does not a])preciably change : 0,339 then becomes 0,338. But 

 i^„ would then become still smaller, viz. 0,07 instead of 0,09 'J. 



1) If p = 7,58 instead of = 7,43^, so b = 0,158 instead of = 0,irj,j, we should 

 also liave found 0,34 for llio value of /3 in tlie vapour, the same value at 

 least as that for the liquid. (AIsp llie assumption ',, = 0,0366 instead of 0,0372 

 might lead to the desired purpose).
