After careful washing and drying the entire, plants were 
analyzed.

As the dry matter had increased very much in those plants 
which were treated with sugar, the percentage of the nitrogen 
compounds is very much lowered. I calculated therefore the fol¬ 
lowing table to show the relation more clearly :—

(1) Asparagine nitrogen was here determined without previous removal of the bases 
by phospho-tungstic acid; therefore the result is somewhat too high. 
(2) For the calculation the absorbed nitrogen was subtracted from the total nitrogen; 
otherwise a true comparison is impossible.
