§32. The average coefficient of digestion of the dry matter 
in this hay obtained by the usual method was found to be 62.05, 
It is given as 63.95 on page 23 of Bulletin 93, but this is a mistake 
It should be 62.05.

§33. In the preceding table, it will be noticed that the amount 
of reducing sugar found in the one per cent, sodic hydrate extract 
for the dung exceeds the amount found for the extract of the hay 
by a very considerable amount, 71.91 per cent.
