Determinations of snlpliur were made in all tlie experi- 

 ments, and showed that in every case but one (Sheep IL 

 in Period III.) a gain of this element also took place. 



These results show, beyond all reasonable doubt, that as- 

 paragin, at least, is really a nutrient, and that when added 

 to a fodder poor in albuminoids it may cause a gain of 

 protein by the body, just as we have already seen that the 

 albuminoids may. 



It probably acts in the way already suggested, viz., by 

 taking the place of a part of the circulatory protein and 



* To render the results better comparable, the nitrogen of the as- 

 paragin and gelatin has in all cases been multiplied by 6 25 and 

 counted as protein.
