THE DISSOCIATION CURVE OF HEMOGLOBIN 117 



Hb-acid and sodium hsemoglobinate which exist at any particular 

 degree of acidity of the fluid. Fig. 38 shows as the ordinate the 

 quantity of haemoglobin united to base (BHb) in proportion to that 

 not so united (Hb) and as the abscissa the pK. It will be seen more- 

 over that the graph is equally true whether the haemoglobin is in 

 the form of oxy- or CO-Hb — a point which will be considered in 

 Chapter xiv.
