Tt will be noticed from the above analyses that in most of the 

 samples the percentage of lime is over 9fW, though in some it is 

 under SO'*. Another noticeable feature is the low percentage of 

 both magnesia and alkalis, specially the latter. One shows the 

 presence of much 1LS and another of appreciable amounts of 

 BO, 



I* is the custom for boot sugar manufacturers to burn their 



lime themselves, for the reason that the carbon dioxid gas is also 



1 in the process. For the production of the best results, it 



b therefore important that the limestone shall be of proper qual- 



and the burning conducted in the right manner. 



Silica is a deleterious impurity, as it not only causes the Btone 



fuse but also lowers the amount of lime and carbon dioxid 



duced to each ton of Btone used. This latter point is of course 



gard to any other impurities which may be present 



Too lit! Bhould also be avoided, as it decreases the amount
