CLASSIFICATION OF THK PKOTKII 

 The following classification is both convenient and c.m. 



CLASS I. Naticc "Hnunins. 



Soluble in distilled water. Solutions coagulated on heating, 

 especially in presence of a dilute (acetic) acid. Not precipitated 

 .rbonates of the alkalis or by sodium chloride, m- generally 

 by solutions of neutral salts.

 tions ; soluble in a<-id< and alkali^. Solutions not coagulated l, v

 or Native alkali-alliumin. :
