ALBUMINOID AND NON-ALBUMINOID NITROGEN. 
AS there isa difference in value for feeding, between the 
albuminoid and non-albuminoid nitrogenous substances I 
have in most cases determined the total nitrogen and the 
true albuminoid nitrogen, taking the non-albuminoid nitro- 
gen—amides, etc., by difference. These are given beyond 
and the per cent. of total nitrogen in the amide form, also 
with the grasses the date at which they were cut, all of 
which, except No. 10, were cut in bloom. The timothy was 
from a newly seeded field and taken from the mixed grasses 
as an average of the timothy for the field. With the ex- 
ception of the daisies and buttercups the other grasses were 
all from the Station grass plats. For the determination of 
the albuminoid nitrogen, Stutzer’s } cupric-hydrate method 
was used which in brief is as follows: 7 
One gram of substance is placed in a beaker with 100 c.c. 
of alcohol and 1 ¢.c. of acetic acid, heated to a boil, cooled, 
then carefully decanted through a filter, leaving all the in- 
soluble matter in the beaker, and well washed with warm 
alcohol to remove all acid. The residue is then covered 
with 100 c.c. of distilled water and heated to a boil, when 
partly cooled add from 0.3 to 0.4 grams hydrated copper
