The method of Wroblewski was quite different from 

 that of Amagat, yet their results agree sufficiently well with 

 one another. 



I then proceeded to the calculation of pressures by equa- 

 tion (1). The results are contained in the following Tables ; 

 the corrected values in I., II., III. agree very well with those 

 given by Margules and Galitzene, but those in IV. show 

 some, though small differences.
