A shows that the condensation of nitrogenous compounds which normally 

 takes place in ripening peas is retarded by the doses used in this experiment. 

 The consideral)le accumulation of amides in 5, 6 and 7 and possibly in 4 indicates 

 undoubtedly a katabolism which must be related to the death of the plants, a 

 hypothesis which is also supported by the results obtained in B and C, in which 

 series the portions were additionally allowed to remain for 2 respectively for 4 

 days in normal conditions after the exposure to ether to demonstrate the after- 

 effect of the etherization, ß., shows indeed a result which demonstrates a retaida- 

 tion of the condensation; yet a comparison of this result with that of A.^ shows
