etable albumins are not identical with those derived from 

 the animal. 



As respects the Fibrins we have already seen that there 

 is no similarity in properties between that of blood and 

 those obtained from gluten. The analyses of the two 

 gluten-fibrins show either that these substances are quite 

 distinct or that they have not yet been obtained in the 

 pure state. 



The Vegetable Caseins, as analyzed by Ritthausen, are 



* The analysis of milk casein should include 0.9 phosphorus. Tin- 

 buckwheat casein contained o.'.t phosphorus, which is not included in 

 the analysis. Whether phosphorus is an ingredient of casein, or an 

 "impurity," is not perhaps positively established.
