Fig. 1. Relationship between the mole per cent saturated acid and mole 

 per cent fully saturated triglycerides.^^ The broken line represents the pro- 

 portion between the fully saturated glyceride content and the proportion of 

 saturated to unsaturated acids if these were distributed so that a maximum 

 amount was in a 1.4:1 ratio. The lower figure represents an enlargement 

 of the lower central area.

 proportion of the acid, ^i, approaches 67%. Finally, only after the con-
