* In the first analysi.s above the sucrose was sought for by a polarlscope, but so Utile was present 

 that no rotation coiilil bo observer!. It is fair to presume fi-om a study of the analyses ■which follow 

 that 0.06 per cent, sucrose was piesent. 



t In this analysis the chips wore left over night, and in the morning no sucrose could be found. It 

 had all been inverted, and appears therefore with the glucose. 



WASTE WATERS. 



The weight of water discharged with each cell was nearly one-third 

 greater than that of the chips ; therefore the percentages found are in- 

 creased by one-third to represent the real loss.
