In lieu of article on "weight of Diffusion juice compared 

 with weight of cane worked" pp. 53 and 54, Bui. No. 14, read as 

 follows : 



Number of cells filled 83. 



Weight chips in each cell z 83.25 -7 83 - 1. 003 tons z 2006 

 pounds. 



Normal weight of juice in 2006 pounds of cane 1805 pounds. 



Additional weight of water added by diffusion 71 1.8 pounds. 



Percentage of increase over normal juice 711.8 X 100 - 

 1805 ~ 30.4 



press and dried contained of moisture 45.37 per cent. The total weight 

 of dry matter obtained in the press cakes was, therefore, 2,582.9 pounds. 

 Analyses of the dried cake gave the following results: 



Per cent. 



Albuminoids 9,585 



Sucrose Trace. 



Glucose Trace. 



Other organic matter 17. 45 



QUANTITY OF LIME USED. 



As is seen under sorghum experiments it required 1.5 per cent, lime 

 to produce a good nitration. 



I felt sure that the juice from the sugar-cane would not require as 

 great a quantity. At the preliminary trial 1 per cent, of lime was used 

 and the cakes formed were perfect, firm, and hard. 



In the second run only .75 per cent, of lime was used, and the cakes 

 were equally as good. There is little occasion for using less lime than 

 this, for with this quantity the carbonatations were easily finished in 

 fifteen to twenty minutes. 



COEFFICIENT OF PURITY IX SECOND TRIAL. 



Per cent. 



Of the mill juices the coefficient was 73. 8 



Of the diffusion juices the coefficient was 72. 6 



Of the carbonatated juices the coefficient was 72. 3 



Of the sulphured juices the coefficient was 70. 9 



Of the first semi-sirup the coefficient was 74. 6 



Of the second semi-sirup the coefficient was 73. 5 



In both trials it was seen that the coefficient of purity was increased 

 during the process of evaporation. This was, doubtless, caused by the 

 precipitation of some of the lime salts held in solution by the juices.
