FIG. 12. Ordinates are the c.c. of 0.1 N NaOH, KOH, Ca(OH) 2 , and Ba(OH) 2 

 in 100 c.c. of 1 per cent solution of casein. Abscissae are the pH of the solution. 

 The curves for the four alkalies are identical, proving that Ba and Ca combine 

 with casein in equivalent proportion. 



trical way in which they combine with crystalloidal acids. 

 This is equally true for the combination of these bases with 

 isoelectric albumin (Fig. 11), with casein (Fig. 12), and with
