diamiiio-compounds on arcount of the small qnantilies in which they are found. 

 As regards the nionaniino-acids the ether has in all cases retarded the decrease 

 during the ripening-process, and with regard to the diamino-acids the two smallest 

 doses seem to have accelerated the decrease. 



I have always found in the experiments on potato-tubers that etherization 

 produced a retardation of the processes affected by the wounding. As it would be 

 a matter of interest to learn whether etherization would produce metabolic processes 

 parallel with those produced by wounding, a few experiments were made on 

 etherization on wounded ripening seeds of Pisum and Lupinus: 



Experiments with Ripening Lupines. 



5 "common-legume" portions of the same material as used for the former 

 experiment. The seeds of the last three portions were wounded by being cut 

 across. Temp. 16 — 19°. Jars of 14 liters capacity were used for the etherization: 



The experiment demonstrates that the decrease of amides which normally 

 takes place simultaneously with a formation of proteids during the ripening-process 

 has been accelerated by injury. The smallest dose slightly retarded the accelera- 

 tion of the condensation, while the largest dose produced an increase of the amides 

 during the exposure of two days' duration. When regarding separately the mon- 

 amino-acids and the diamino-acids, it is seen that the smallest dose has accelerated 

 the decrease of the monamino-acids, which had already been accelerated by the 

 injury. As regards the diamino-acids both ether doses have on the contrary caused 

 an increase. 



Experiments on Ripening Peas. 



A. Young seeds were used (dry-weight = 19-44 7" of which 5-06 "/o N). Of 6 

 "common-legume" portions the three portions were each divided into two, each 

 seed being split through the embryo .and the hilum. In this manner 9 portions 

 were arranged from the 6 original ones. For the etherization jars of 14 liters 

 capacity were used both in this experiment and in the following one:
