The third dimension exhibits at least an equal dif- ference, as may be seen by comparison of the outlines of cross- sections, Fig. 10, a, b, c, drawn at identical magnifications. The male and female normal controls may be regarded as typical for size of- the gonads at this stage, for I have examined several other.
