juice. After the first carbonatation about 33 per cent, of these sub- 

 stances have been removed. 



A study of the tables will indicate the advantage which may be ex- 

 pected from the application of the lime and carbonic acid method of 

 defecation to sorghum juices, with such modifications as the peculiar 

 nature of these juices require. 



If the experiment could be made on a large scale, I think the practi- 

 cal advantage of the process over any other now in use would be at 

 once apparent.
