after having stated that no other sugars were present in the liquid. 



I pulverised the dried residue left behind after the alcoholic 

 extraction of the pulp and extracted part of it with cold water. 

 This extract was evaporated to a small volume and precipitated with 

 alcohol. The precipitate was collected on a weighed, ashless Alter 

 washed with alcohol, dried, weighed, incinerated and the loss of 

 weight occasioned by the combustion of organic matter was recorded 

 as dextrin after I had convinced myself by the red coloration which 

 iodine solution produced in the solution of such a precipitate that 

 it really was dextrin. 



A second portion of the residue was hvdrolysed with hydrochloric 

 acid under pressure and the amount of glucose thus obtained calcu- 

 lated as starch. Finally, I determined the percentage of nitrogen and 

 calculated from this figure the amount of albuminoids by multiplica- 

 tion with the factor 6,25. The figures for the different analyses 

 follow here :
