Diffusion 



The mean purity of the mill juices during the interval named was 64.8 

 and of the diffusion juices 48.7, a loss of 16.1 points. 



During the rest of the season the mean purity of the mill juices was 

 40.7 and of the diffusion juices 40.0, a loss of only 9.7 points. 



The glucose per hundred of sucrose, during interval noted, in the 

 mill juices was 26.07. In the diffusion juices it was 52.13, an increase 

 of 26.06 points. During the rest of the season the glucose per hundred 

 of sucrose in the mill juices was 54.68 ; in the diffusion juices 77.77 ; an 

 increase of 23.09 points. 



The most striking point about these comparisons during the interval 

 named is the enormous difference between the mill juices and those of 

 diffusion. In no other part of the season does the deterioration of the 

 juice in the battery show itself to such an alarming extent. 



There is only one explanation of this which appears satisfactory, and 

 that is the fact that during this time the temperature of all the cells 

 under pressure except the two central ones was kept within the limits 

 of fermentation. The cane during this period, as a glance at the analyses 

 will show, was by far the best worked during the entire season. The 

 analyses of the chips made during this time shows the following ineaii
