For the two lots of cane, covering the entire run of twenty-five] 

 days, the average percentage of total solids is 15.07 per cent; ofi 

 sucrose, 11.16; of reducing sugar, 2.15; and the average purity coeffi-f 

 cient 73.63.

SEMISIRUPS. 



The average composition of the semisirups as shown in Table Vj 

 gives a general indication of the degree of concentration. The low-j 

 est percentage of total solids is found in No. 4003, namely, 38.4 per! 

 cent, and the highest in No. 4009, namely, 55.5 per cent. The total 

 solids in all of the semisirups analyzed average 48.2 per cent. 



The lowest sucrose in the semisirups occurs in No. 4003, 30.19 per) 

 cent, and the highest in No. 4008, 46.56 per cent, the average amount 

 of sucrose being 38.37 per cent. 



The smallest amount of reducing sugar in any of these samples is 

 found in No. 4008, namely, 5.06 per cent, and the largest amount j 

 in No. 4007, namely, 10.17 per cent. The average amount of reduc- 

 ing sugar present is 7.74 per cent. The percentage of inversion a isl 

 greatest in sample No. 4007, 9.30 per cent, and least in No. 4011, 

 namely, 1.09 per cent. 



The semisirups were not all subjected to analysis, but the figures | 

 given in the table show the general character of these products. 

 It is evident, by comparison with the figures given for the juices 

 and the completed sirups, that nearly all of the changes effected 

 take place during the conversion of the semisirups into sirups, there 

 being comparatively little difference between the composition of 

 the juice and of the sernisirup.
