§42. The treatment with boiling one per cent, hydric chlorid 
aims at the removal of easily hydrolized substances which might 
yield fufurol on distillation with the stronger, 12 per cent., acid. 
This treatment removes considerable quantities of furfurol yielding 
substances from the hay which apears to be wholly digestible for we 
find none in the feces. On the other hand, the hydric chlorid, one 
per cent, solution, removes hydrolyzable substances from the feces 
corresponding to 1.03 per cent, of galactan. The one per cent, hy¬ 
dric chlorid solution removes from the hay 1.52 per cent, of furfurol 
and contains reducing sugars equal to 3.01 per cent, of galactan 
which is probably the source of the reducing sugar, as the hay 
yields when treated with hydric nitrate, sp. gr. 1.15, according to the 
^official method, mucic acid corresponding to 2.86 per cent, galactan, 
so it seems probable that both pentose and hexose sugars are rep¬ 
resented in the composition of the hay.
