A second series of tests were then carried out to ascertain 
the effect of still more dilute solutions of caustic lime on the mineral. 
The amount of Oa(OH) a in this approximately centinofmal solution 
was far below that required for a saturated solution and slightly 
more than was necessary to satisfy the foregoing equation. 
It will be seen that the quantity of mineral used in this series 
of experiments was 0.45 gms. as against 0.5 gms. in the first series. 
This was only a matter of convenience in keeping the bulk of caustic 
lime solution at 400 c<\, at the same time giving an appreciable 
amount of Ca(OH) a over that required by theory. The amount of 
caustic lime used was equal to 0.3152 gms. for 0.5 gms. of alunite, 
which is 0.0493 gms. excess of the amount required to satisfy the 
equation rhcwn above.
