TABLE No. 50. Single and double polarization of mill juices, Magnolia. 



In Table No. 51 is given the single and double polarization of sirups 

 derived from the juices in Table No. 50. 



The same precautions were taken in the selection of samples and in 

 the analytical manipulation as in the preceding table. 



The increase in the percentage of sugar on double polarization in the 

 case of the sirups is equivalent to about one-half of the percentage of 

 glucose present. It will be noticed in Table No. 50 that there are nu- 

 merous examples of a like proportionate increase. In sample No. 3, in 

 Table No. 50, there is an actual loss of sucrose, the second reading being 

 .07 less than the first. This- result was doubtless due to some error 

 which all the precautions taken could not avoid. 



TABLE No. 51. Single and double polarization of sirups from mill juices. 



In Table No. 52 are found the data of polarizations of various samples 

 of molasses taken at different times during the season. Unfortunately, 

 in only three cases was the percentage of glucose determined. In these 

 cases the increase on double polarization is equal to almost half the per- 

 centage of glucose present. The mean increase, however, viz, 8.30 per 

 cent., would probably not have been much greater than one-third of the 

 mean percentage of glucose present in the molasses.
