It will be noticed in the above tables that the analyse have been re- 

 duced to the basis of a molasses of a stated density. This farili: 

 the comparison of the results, the percentages being directly compil- 

 able with one another. 



The arbitrary density 50 Brix (Baurne 27.2) has been taken Im 

 molasses from firsts and 70 Brix (Bauine 40.3) for molasses from 

 seconds. 



Fifty and seventy-six degrees Brix were selected as standards of 

 comparison, since they represent approximately the average densities 

 of molasses from first and second sugars. 



LOSS OF SUGAR IN THE PROCESSES OF MANUFACTURE. 



Unless careful arrangements for measurements are provided it is 

 almost impossible to trace losses in manufacture. At Magnolia there 

 is no provision for measuring either sirups or masses cuitcs. The quan- 

 tities of cane juice, sugars, and molasses are accurately known, and 

 they, together with the analytical work, are the basis for the following 

 calculations :
