Thus the whole pulmonary tract communicates widely with the pharynx at the 35 s stage. Its complete delimination falls within the period covered by Chapter X. The continuity of the expansions that form the lung primordia, with the series of visceral pouches as shown in Fig. 100, is especially noteworthy as suggesting a theory of the phylogenetic derivation of the lungs.
