gen. There should however, be a slight reduction made 
because of the fact that some of the nitrogen is present in 
a form of much less value than the proteids. The second 
column m the accompaning table gives the percentage 
of the total albuminoids corresponding to the amide nitro¬ 
gen round. . 1 he following is the amount of amide nitro¬ 
gen found in the respective samples :

The proportion of proteids in the nitrogenous sub¬ 
stances of alfalfa is represented, according to these results, 
by 89.13 P er cent., for the first cutting ; 79.93 per cent, for 
the second cutting ; and 94.97 per cent, for the third. The 
percentage here given for the third cutting being based 
upon a single sample of hay, and at variance with the other 
results, is at best doubtful ; it is, however, the result ob- 
V ^ ha Y e f° un d but one other series of analyses of 
alfalfa, in which the amide nitrogen is given, i. e., by Mr. H 
H. Harrington, in Texas Bulletin No. 20, 1892. The dates 
on which the samples were taken are given instead of the 
development of the plant ; but, as the period of collecting 
covers forty days, I infer that the samples represent success¬ 
ive stages of development corresponding approximately to 
those given in this bulletin. The third column gives the 
percentage of total proteids corresponding to amide nitro¬ 
gen found :
