The data in Fig. 4 represent the calcium/phosphorus re- 

 lationship in the four principal experimental groups. On 

 the assumption that the protein content is a basic unit of 

 structure, the values are compared in relation to protein. 

 One advantage of this formulation is that the intercept of the
