In B the smallest dose has had no influence on the condensation, already 

 accelerated by the injury, while the largest of the doses used has produced an 

 increase of the amides during the two days of exposure. 



A demonstrates that both the monamino-acids and the diamino-acids decrease 

 during the ripening-process, a phenomenon which was also proved with regard to 

 ripening lupines. Injury of the organs accelerates this process in both the above 

 mentioned groups of nitrogenous compounds. By adding a dose of Ole. c. ether 

 per liter air space the monamino-acids further decrease, while the diamino-acids 

 increase. Larger doses than this affect an increase both with regard to the mon- 

 amino-acids as to the diamino-acids. Is is difficult to explain the fact that the 

 smallest dose, used in A, has retarded the metabolic processes both of the mon- 

 amino- and the diamino-acids in uninjured seeds, whereas it has accelerated this 

 process as regards the monamino-compounds in wounded seeds. 



Thus the experiments indicate that etherization, carried out with small doses, 

 accelerates some of the processes affected by injury; these results, so small in 

 number, demand, however, corroboration by further investigations.
