Section V.— TABLES. 



26. A. General Tables, giving the Facts of Observation ; namely, W, the weight, in grams, of 

 the solution which contains m gram-molecules of the salt dissolved in 1000 grams of water ; 

 S, the specific gravity of this solution at the temperature, T, referred to that of distilled 

 water at the same temperature as unity. From these data. A, the displacement of the 

 solution, is obtained by the equation A = W/S, and it is expressed in grams of water having 

 the temperature T. The symbol adopted for this unit is Gx- The numbers printed in 

 italics refer to specific gravities observed at the temperature printed in italics.

* The entry in brackets in the column d log A gives log A for the solution of highest concentration in the series. With 

 it and the following values of d log A in the same column the values of log A for each solution in the series can be calculated.
