In table 24 we have the differences in the amount of solvent present and in the 

 values of M, as previously described for the corresponding tables. In figs. 8 and 9 

 these values are plotted as curves.

Nitrate and Strontium Nitrate.

I. Difference between Water Present as Solvent in Single 

 Solution of Magnesium Nitrate and in Mixture of Mag- 

 nesium Nitrate and Strontium Nitrate. 



II. Difference between Values of Af for Magnesium Nitrate in 

 Single Solution and in Mixture of Magnesium Nitrate and 

 Strontium Nitrate.

We have here, again, a uniform decrease in the amount of water present as solvent, 

 showing a uniform increase in the hydration with increase in concentration. The
