In the connective-tissue framework lie networks of lymphatics ; between the framework and the surface of the vesicles are lymph sinuses lined with endothelium (Baber). The large and small lymphatics are often filled with the same colloid material as the vesicles, and it is probable that this colloid material is and %..

Its formation in the vesicles is probabh^ due to an active secretion by the epithelial cells of the vesicles, and to a mixture with it, or maceration by it, of the effused blood mentioned above. In some instances Bal)er found the amount of blood effused into the cavity of the vesicles very considerable, and hence it is justifiable to assume that the destruction of red blood corpuscles forms one of the functions of the thyroid gland.
