CONCENTRATED AQUEOUS SOLUTIONS, AND HYDRATION OF THE SOLUTE. 861 



The curves on p. 860, fig. 3, also show that some salts have a very much larger 

 capacity than others to produce elevation of the boiling point in their solutions. For 

 lithium sulphate an elevation of the boiling point of only from 2 to 3 degrees is 

 obtainable, whilst for lithium chloride more than 40 degrees elevation of boiling 

 temperature may be obtained. 



In the following tables conductivity data from my own observations are given for 

 temperatures 99*4° Centigrade and 0° Centigrade over a wide range of concentration. 



The results are given graphically by the curves figs. 4, 5, 6. A few values of p-^ x 

 at other temperatures are given, also from my own observations.
