lacking. Both may be true, and he points out the analogy 
of fungi which are able to make growth, forming cellulose 
and oils, with a nourishment of only nitrogenous substances, 
but if carbohydrates be also furnished them, a much smaller 
quantity of the nitrogenous matter will be made use of. 
The principal amides observed under normal conditions, 
are, as already stated, asparagin and glutamin. Schulze as- 
sumes”! that this does not indicate a larger production of these 
particular bodies, but that they are less easily regenerated 
than some other forms. In this way he explains the fact that 
the amount of asparagin in lupine germs continued to increase 
for some time after their exposure to light, at the same time 
assuming that the first carbohydrates formed by renewed 
assimilation are employed for the formation of new tissues, 
and not for the formation of albumin from amides. 
he observations of Borodin and Schulze also indicate 
that not all carbohydrates or nitrogen-free substances have 
the properties for influencing the formation of amides or theif 
regeneration. For instance, sugar beets contain considerable 
quantities of amides and cane sugar, existing side by side,

for regeneration, the other does not. It js possible that direct 
combinaton between the two roups occurs with the co-op 
ration of carbohydrates. Atleast Schulze’s conclusion, that
