| [[:File:Gilbert1957 fig14.jpg|Fig. 14]]. The eye-muscle primordia of embryo no. 6258 are superimposed on the brain of another embryo, no. 6520, of approximately the same age and size. The relation of the principal branches of cranial nerve V to the four peripheral condensations into which the four rectus muscles grow is illustrated. Lateral aspect. X 15.

| Attention is called to the four peripheral condensations, about the outer margin of the optic vesicle, into which the primordia of the four rectus muscles have grown. Cranial nerves III, IV, and VI have reached their respective eye-muscle primordia: the primordium of the inferior oblique has appeared as a conspicuous condensation at the distal end of the inferior rectus; a prominent bend (at the point where the trochlea will subsequently develop) has appeared near the distal end of the superior oblique primordium, and the proximal end of the superior oblique has begun to shift medially.
