CONCLUSIONS. 



1. The percentage of the juice remains almost equal in the first two 

 experiments of each gathering (the difference being due to the difficulty 

 of having in each gathering canes of exactly the same size). It dimin- 

 ishes considerably in the third experiment, doubtless because the canes 

 remain for some time detached from their roots, deprived of their leaves 

 and exposed to the air. 



2. The quantity of juice, of sucrose, and glucose is not sensibly dif- 

 ferent in canes grown from the original seed and from the reproduced 

 seed. 



3. The quantity of sucrose always increases in the experiments of the 

 first and the last gathering all of the divisions; in those of the second 

 and the third the quantity varies without rule according to the various 

 experiments. 



4. The quantity of glucose diminishes in all the experiments from the 

 first to the last gathering, with the exception of the third. 



5. The quantity of sucrose is always the most abundant in the last 

 experiment of the last gathering. 



6. The quantity of glucose is the most abundant in the third experi- 

 ment of the third gathering of each division. 



7. Both the sucrose and the glucose increase in quantity from the 

 first to the third experiment in each gathering and in each division. 



8. The smallest quantity of sucrose is found in the experiments of 

 the first gathering, but it always increases in the third experiment of 

 the first gathering. 



9. The difference in the sucrose is largest between the experiments 

 of the third and the fourth, and smallest between those of the second 

 and the third gathering. 



As to the ratio between the quantity of sucrose and of glucose con-
