be considerably lower since the anion SO4 in combination with albu- 

 min is bivalent; while the curve for the osmotic pressure of albumin 

 oxalate should be between the curves for albumin chloride and albu- 

 min sulfate, but much nearer the chloride than the sulfate curve. Fig.

 to bring 1 gm. of isoelectric albumin to different pH. 



4 giving the curves of the osmotic pressures of the four albumin salts 

 shows that this expectation is fulfilled. 



Fig. 5 gives the curves for the combining ratios of acetic acid and 

 dichloracetic acid with isoelectric albumin, showing the same differ-
