For so far as the assumed suppositions hold, the barotropie plait- 

 points given in the table have only physical significance if Tb p i does 

 not become so low that solid phases make their influence felt (cf. 

 Coram. N°. 966, § 5 b), and if moreover the portion of the tp-surface 

 in the neighbourhood of the plait-point is not covered by a portion 

 of the derived surface indicating more stable equilibria (as e. g. will 

 be the case for negative pressures). In how far the indicated baro- 

 tropie plaitpoints will belong to the gas-liquid-plait will be more 

 fully treated in a following communication (cf. footnote 2, p. 660). 



In the first place it follows from table I that with the assumed
