These results are quite confirmatory of those previously given y 

 showing the presence of appreciable amounts of these bodies in all 

 of these common food materials. The grasses make the largest 

 showing, but in the majority of samples the pentosans amounted 

 to from twenty to thirty per cent of the non-nitrogenous extractive 

 matter. 



Accompany the above samples were corresponding samples of 

 the fteces of the animals employed in the digestion experiments, 

 duplicated in each case. We have determined the amount of 

 pentosans in each of these and from the gross weights of the food 

 consumed and fasces excreted have calculated in the usual way the 

 digestibility of the pentosans in question. These digestion experi- 

 ments were conducted under the usual precautions and control, all 

 of which, together with the analytical data, have been published
