The lower curve represents ovum diameter plotted against folhcle diameter for the nine types of follicles (see Plate III) distinguished by Pincus and Enzmann, 19366. Figures 7 to 10 relate the various diameters of ova to the diameters of the enclosing follicles. In the rabbit, Pincus and Enzmann (19366) have identified 9 types of follicles each distinguished by characteristic features of the develop- ing ovum, granulosa and theca (see Plate III). When the.
