FIG. 22. Curves representing relative viscosity of 0.8 per cent solution of 

 originally isoelectric gelatin brought to different pH. The curves for relative 

 viscosity of gelatin chloride, phosphate, and oxalate are practically identical. 

 Relative viscosity is given as time of outflow of gelatin solution divided by time 

 of outflow of water through viscometer at 24C.

 These latter measurements agreed in all experiments within 1
