N. YAMASAKI ; THE STATE OF CANE SUGAR 



be judged by the following results obtained with manured cane 

 (a) and unmanured cane (b) taken from the experimental field of 

 the Government.

and ground-nut cake. 



The relative amount of sugar in the top, middle, and lower 

 part of the cane is seen from the following table : — 



Sp. grav. Sucrose. Glucose. Cocffts. of purity. 



Top. 1.05s 12.32 .38 92.3 



Middle. 1.070 14.54 -27 89.7 



Lower part 1.068 IS-I9 '-^S 94.9

Near the top, therefore, there is much more glucose or 

 uncrystallzable sugar than near the base. 



Also both healthy and diseased canes were examined, with 

 the following results : 



Sp. grav. Sucrose. Glucose. Coeffts. of purity. 



Healthy. 1.055 12.19 46 90-2 



Diseased. r.050 10.43 -66 80.0 



The diseased cane had been attacked by insects, was in- 

 jured by the wind, and was covered with fungi and worms. The 

 yield of sugar was thus considerably decreased. Samples of 

 juice from a manufactory of a Chinese were separatedly examined, 

 the average result being as follows : 



Sp. gr. Sacharimeter Brix. Sucrose. Glucose. Coeff. of purity. 



1.061 15.6 13.48 .61 86. 



In the south the quality of the juice is probably superior to 



this. 



(1)1 divided the whole body into tlirce equal parts and took equal weiglits of these 

 parts.
