DISCUSSION OF CHEMICAL DATA. 



61 



proportion ol the samples collected complied with the two moisture 

 requirements specified : 



Percentage of samples complying with two maximums of moisture content. 



The average shows that only 29 per cent of the samples collected 

 would comply with the 32 per cent requirement, while if 35 per cent 

 were considered the maximum then 72 per cent of the samples 

 would be satisfactory in this particular. 



A sirup that is made too thin will not keep because of fermentation, 

 while if too thick the sucrose will crystallize. Of the 395 samples 

 collected within the United States 71 were crystallized to such an 

 extent that they could not be analyzed, the liquid above the crystals 

 showing a moisture content of less than 32 per cent in most of the 

 cases. Of the remaining 324 samples 45 had crystallized somewhat 

 and their moisture content was as follows: 



Moisture content of 45 samples showing slight crystallization. 



It is seen that sirups with as high as 34 per cent of water in one 

 case, 33 per cent in two cases, and 32 per cent in seven cases had 

 crystallized, while none with 35 per cent had crystallized. Crystal-
