TABLE 5. 



We have therefore, continued tlie determination in two concen- 

 trations, for 24 hours to make sure that also after this time the 

 lime content would suiFer no further change. 



In these determinations the "residue" was also analysed to ascertain 

 whether its composition would point to calcium hydroxide as solid 

 phase or whether perhaps any deviations did occur. 



The results in table 6 show that the solid phases consisted 

 practically of calcium hydroxide only. 



TABLE 6. 



In lig. 3 the figures of table 5 (8 hours' shaking) are given in a 

 graphic representation and connected by the line mi. 



The values found by Claassen (for 60 minutes' stirring) are represented 

 therein by the encircled points. 



The line a n (tig. 3) is a part of the line AN in fig. 1. 



In figure 3 is also drawn a line J- g (corresponding with the line 

 F G in fig. 1), of which only a few points have been determined 

 (Table 2) but which probably will have a similar course as that 

 indicated in the figure.
