236 REPORT OF THE CHEMIST OF THE 
but are made up of a large number of nitrogenous products, which 
have usually been classed alike for feeding purposes. The white 
of an egg, the tenacious mass — gluten — which remains on wash- 
ing the dough from wheat flour, and animal muscles are common 
examples. : 
Not all of the nitrogenous matter of feeding stuffs isin the form 
of albuminoids, but often a considerable portion isin what may be 
termed a transitory state known by the general name amides. 
Amides have a less nutritive value than the true albuminoids. 
However, they probably have a greater nutritive value than many 
experimenters have assigned to them. 
Orude fiber is the woody portion — frame-work — of vegetable 
matter which is unacted upon by dilute acids or alkalies. Crude 
fiber has little direct nutritive value to the animal. 
Nitrogen-free extract.— This is a mixture of various substances 
which are sometimes called carbo-hydrates. The starches, sugars, 
dextrine, pectic and mucilaginous bodies, gums, etc., are the 
principal substances of this class. : 
Fat.— The other extract of feeding stuffs is a mixture of oils, 
wax, coloring matter, etc. Cotton-seed oil, linseed oil, corn oil, 
etc., are common examples. : 
ANALYSES OF FODDERS. 
During the past year, a large number of fodder analyses have 
been made. A large part of these analyses are given under their 
appropriate heads, but there remain some of a miscellaneous nature 
erouped under the above head which do not appear in full else- 
where. Besides the regular analyses, there have been made deter- 
minations of the albuminoid and non-albuminoid nitrogen, the 
digestibility of the albuminoids and in some cases ash analyses 
for the fertilizing ingredients. 
Unless otherwise stated, the grasses were all cut in full bloom.
