The rudiment of the enteric muscles has followed this ventrad growth, but only imperfectly so. A short distance back from the ventral edge of the rudiment of the mesen- teron are four scattered muscle nuclei, while dorsad of this the forming muscle cells form a continuous layer which is joined to the cardioblasts. The appearance of the section suggests that the cells of the rudiment of the enteric muscles had been forcibly dragged apart by the rapidly growing epithelium of the mid- intestine. A section through an embryo of Stage XIII-XIV (Fig. 82) shows the process of differentiation nearly completed. The hypo- dermis extends on each side up to the dorsal mid-line. The.
