The distribution of nitrogen and also that of the furfurol, in 
these various extracts has been determined, but no attempt has been 
made to distinguish between arabinose and xylose, all being cal¬ 
culated as xylan. Determinations of mucic acid were made on 
these fodders, and the sugar obtained by treating the alfalfa hay 
with I per cent, hydric chlorid has been considered as being derived 
from galactan, which is also probably present, according to our 
results, in some of the other fodders. 
The reducing power of the sodic hydrate extract has been in¬ 
dicated as xylan with an interrogation point, because it is very 
probably not derived from xylan. The quantity of this sugar is al¬ 
together insignificant, except in the case of the saltbush, in which it 
is relatively large.
