[Figure 5.] A surface view, in profile, of an embryo at the time of the origin of the limbs. × (about) 5.
[Figures 5A]-[5I]. A series of transverse sections through an embryo of the age shown in figure 5. × 7.
[Figure 5J.] A composite drawing of reconstructions of the enterons of two embryos of the age of the one shown in figure 5. One reconstruction was in wax, from sagittal sections, the other was a plotted reconstruction from transverse sections. × 14.
