Fig. 2. Section from the brain of a human embryo 12 cm long

Of about the same age (end of 4th month) and taken from the same place as shown in Fig. 1. Here the pyramidal zone consists of a compact layer with parallel borders, which, with the exception of three transitory fissures presents a perfectly smooth outer surface, and shows no trace of the Retzius papillae.
