SPECIFIC GRAVITY OF DIFFUSION JUICES FROM SUCCESSIVE BARRELS. 



It will be observed that the increase of specific gravity was very 

 regular, and approximately the same in the several experiments. 



The following table gives the analyses of a large number of the juices,, 

 which also show close agreement, and give evidence that the operation 

 was performed without any appreciable inversion of the sugar, the 

 ratio of sucrose to glucose in the diffusion juices being quite as good 

 as in the juices expressed by the mill. 



These diffusion juices, upon defecation and eva^Doration, give syrups, 

 in which the relative proportions of sucrose and glucose remained the 

 same as in the juices, and in general they were like the juices ob- 

 tained by the mill, except in being entirely free from mechanical im- 

 purities.
