duced in common with Cucurbita, two amzdo acids” and pep- 
tone were found ; while during the last year it has yielded still 
another new body, arginin.! 
ese substances are all regarded as secondary products 
derived from the albumin of the seed in a manner analogous 
to the formation of asparagin. Confirmatory of this view is 
the fact that the albumin of lupine seeds when subjected to 
artificial chemical action is converted into amido acids which 
seem to be identical with those produced in germination.” 
It was noteworthy that the amido acids which were so dis- 
finctly present in the germs of lupine were not found in those 
of Cucurbita, and that the asparagin of the former was sub- 
stituted by glutamin in the latter. ; 
; ollowing Borodin’s study of the occurrence of asparagin 
in the young shoots of woody plants, Schulze conceived that 
other bodies might be found here as well as in the erminat- 
ing stages already examined. Twigs of Platanus occidentalis 
were removed from the tree in April and kept in a warm 
room until no further growth was made. The young shoots 
thus developed contained, besides asparagin, an appreciable 
quantity (.5 to 1 per cent.) of a substance corresponding in 
Its reactions to allantoin.” Repeated investigations showe
