contained in the interior of the beet cells and those of the ex- 

 terior liquid. These transformations take place through the 

 membranes of the tissue, and there is a real phenomenon of 

 diffusion, which in reality explains the use of the word. The 

 substances dissolved in the" liquid of the cells pass through the 

 porous membrane with different velocities, which depend upon 

 their condition of fluidity and the complexity of their molecules. 

 The saline substances are most rapidly diffused through the 

 tissues. Then there follow the sugar, amides, and, last of all, 

 the albuminoids, and the cellulose and pectic substances. For- 

 tunately these transformations are in direct ratio to the degree 

 at which exhaustion takes place in the diffusion battery. 



The main object the sugar manufacturer has in view is to ex- 

 tract from these cossettes as much sugar as possible and to leave 

 behind a maximum, so to speak, of albuminoids and other sub- 

 stances which are likely to offer difficulties in the subsequent 

 operations of the various phases of sugar extraction. These 

 transformations will end at a certain point and the exhausted 

 cossettes will ultimately consist of a residuum product that will 

 be very valuable for cattle feeding. 



As all the substances dissolved in the liquid of the cells and 

 the order in which they diffuse are known, we are able to ap- 

 proximate, with a considerable degree of accuracy, the composi- 

 tion of the final exhausted cossettes. They are poor in sugar 

 and relatively rich in albuminoids and pectic substances. The 

 salts have also been eliminated to a considerable extent. This 

 product as it leaves the diffusion batteries has about the follow- 

 ing composition:
