Theoretic Determination of Vapour-pressure. 

 and in consequence of tins we can write 



In applying equation (1) to saturated vapour, the pressure 

 of the saturated vapour was denoted by P, and the fraction 

 P/E.T by II. The volumes of the saturated vapour and the 

 liquid standing under the same pressure were denoted, in the 

 usual manner, by s and a : but for the differences s—a and 

 a—a. the simplified symbols TV" and w were introduced. In 

 order to determine the quantities II, TV, and m in their de- 

 pendence on 0, first all four quantities were expressed as func- 

 tions of \= log (TV 'ic); and then, to facilitate the further 

 calculations, a table was added, from which for every value of 

 6 the corresponding value of X. can be taken. At the same 

 time I remarked that, after the calculation of the table for A., 

 there would be little further difficulty in calculating a similar 

 table for II, TV", and w also; this I take leave to communicate 

 infra: —
