of Bamboo Shoots.

Since O. Kellner 1 2 discovered the fact that all green plants 
normally contain nitrogenous non-albuminous substances in 
considerable proportions, and since J. Borodin 1 published his 
well-known memoir “ Über die physiologische Rolle und die 
Verbreitung des Asparagins im Pflanzenreiche,” the study of 
nitrogenous non-albuminous constituents of plants has received 
special attention among distinguished German authors, among 
whom E. Schulze is prominent. Indeed, the fact that albumi¬ 
noids undergo a far reaching change in the organism of plants 
has been brought to light, since Pfeffer confirmed and extended 
the observation of Th. Hartig on the presence of asparagine 
in the vegetable kingdom. It was, however, soon discovered 
by the researches of E. Schulze and J. Barbiéri 3 on pumpkin 
sprouts, that asparagine is not the sole product of the decom¬ 
position of albuminoids in vegetable bodies, but that there 
occur many other substances of an analogous nature known 
to have been produced from albuminoids, since they found 
in the sprouts, besides asparagine and glutamine, also tyrosine 
and leucine. The same fact may also be induced from the
