In the immature gi'een seed of difi'erent legumes, the chromogen can 

 readily he detected, so that it is possible to predict whether the seeds may 

 be coloured or n(jt in adnlt condition. S;) far the writer has found, the 

 colourless or wliite seeds show practically no chromogen reaction when they 

 arc stiU young, tlie relation of the pigment to the chromogen being quite well 

 marked.
