FINISHED SIRUPS. 



Table VI, showing the composition of the finished sirups, is of great 

 interest. The density of the finished sirups, is quite uniform, the 

 smallest percentage of total solids being found in No. 3998, namely, 

 73.4 per cent, and the highest amount being found in Nos. 3977, 

 3980, 3986, 3987, and 3988, namely, 76.8 per cent. The average 

 total solids in the finished sirups is 75.73 per cent, showing an aver- 

 age water content of 24.27 per cent. 



The smallest quantity of sucrose in the finished sirups is found in 

 X<>. 3978, namely, 38.77 per cent, and the highest quantity in No. 

 3 ( .)!)7, namely, 53.76 per cent. The average amount of sucrose in the 

 finished sirups is 46.05 per cent. The smallest quantity of reducing 

 sugar is found in No. 3997, namely, 16.72 per cent, and the highest in 

 No. 3978, namely, 34.34 per cent. The average percentage of reduc- 

 ing sugar is 24.49 per cent. The percentage of inversion, calculated 

 accordingly to the formula given in Bulletin 93, is smallest in No* 

 3995, namely, 13.15 per cent, and the highest in No. 3982, namely, 

 31.98 per cent. In two instances the percentage of inversion was not 

 calculated. 



The ratio of the total sugar to the total solids shows a comparative 

 freedom of the finished sirups from soluble products other than sugar. 

 The smallest ratio of total sugar to total solids is found in the case of 

 6662 No. 10306 3
