CHAPTER III 



THE EFFECT OF TEMPERATURE ON THE AFFINITY 

 OF HAEMOGLOBIN FOR OXYGEN 



IN perusing the last chapter one point will not have escaped 

 the reader. I may state it as follows. Let it be granted that the 

 dissociation curve of dialysed haemoglobin takes the form of a rect- 

 angular hyperbola, passing through the point A and approximating

to the line by OF. It is possible to draw any number of such curves. 

 Why should the curve of haemoglobin be this particular one, which is 

 represented by the thick line in Fig. 13, rather than any other, such 

 as those represented by the thin lines ? 



Let us go back upon the argument which we have already used.
