extract. The two reagents that remove the greater portions of 
the fnrfurol are the hyclric chlorid and sodic hydrate, but the cel¬ 
lulose often contains as much as either of these. The distribution 
of the furfurol in the various extracts of alfalfa, the saltbush and 
corn fodder, may be restated to make clear these differences.

§163. These results point to very great differences in the* 
properties of the compounds yielding the furfurol. A further 
study of the different tables will be seen to indicate that the leaves 
and stems are very different in this respect. 
§164. The coefficients of digestibility as indicated by the 
results obtained point to further differences. We have for the 
coefficients for the furfurol in the above extracts the following:

§165. The coefficient given for the digestibility of the furfurol 
in the cellulose of the saltbush includes the portion removable by 
treatment with chlorin, etc. It will be recalled that, in the case of 
the saltbush, the group which we designate crude fibre has an 
exceedingly low coefficient of digestion, 15.35 being the highest 
obtained with either of the sheep. 
§166. We will see later that the significance of these differ¬ 
ences are quite important. The testimony of the scales in regard 
to the live weight of these animals is that the alfalfa is an excellent 
fodder, that the corn fodder is good and that the saltbush is a very 
poor one. I am fully aware of the importance attached to the ni¬ 
trogenous substances present in a fodder in the theories of animal 
nutrition, but the results so far obtained in this experiment, as I 
interpret them, point clearly to the equal importance of the character 
of the carbohydrates in the fodder. 
§167. The amount and distribution of the proteids in the fod¬ 
ders and their respective extracts ha^'e already been given, but we
