. The elements of Embryology. Embryology. 192 THE THIKD DAY. Fig. 66. [ I Section through the External Glomerulus of one of THE Anterior Segmental Tubes of an Embryo Chick OF ABOUT 100 hours. gl. glomerulus ; ge. peritoneal epithelium ; ^Vd. Wolffian duct ; ao. aorta ; me. mesenteiy. The Wolffian tubule, and the connection between the external and internal parts of the glomerulus are not shewn in this figure. In the case of the remaining tubules developed from the S-shaped cords, the attachment to the peritoneal epithelium is very soon lost. The cords acquire a lumen, and open into the Wolffian duct. Their blind extremities constitute the commencements of Malpi- ghian bodies. â In the posterior part of the Wolffian body of the chick the intermediate cell-mass becomes very early detached from the peritoneal epithelium, and at a con- siderably later period breaks \r^ into oval vesicles, which elongate into Wolffian tubules. In addition to the primary tubules, whose development has just been described, secondary and tertiary tubules are formed on the dorsal side of the primary tubules. They are.
