CANE SUGAR.

Tables 35 and 36 summarize the progress made in suppressing dilu- 

 tion. The first gives the upward displacements of the manometers 

 which attended distortions of the rubber stoppers under pressure. 

 They are to be regarded merely as a symptom of such distortion, and 

 not as a measure of the increase in the capacity of the cells. The more 

 important of the two tables is 36, which gives the losses in rotation, 

 that is, the amounts of dilution from all sources which the solutions 

 suffered while in the cells. 



Table 36. — Cane sugar, Series I to VIII. Loss in rotation (degrees). 



*Loss in rotation not determined. 



The main object in view during the second period of the investigation 

 was the development of the method — specifically, the suppression of 

 thermometer effects and dilution — and hitherto the data of Series I to 

 VIII have been arranged or discussed principally with reference to the 

 progress made in that direction. The present chapter might properly
