The intracellular position of the Golgi apparatuses in the basal cell layer of the corneal epithelium in embryonic and hatched chicks has been studied in the light microscope by impregnating the Golgi apparatus with silver. During two distinct periods in development the Golgi apparatuses in the basal cells shift from an apical to basal position. Each of these periods correlates in time with the appearance of an acellular collagenous matrix beneath the epithelium. Examination of the basal epithelial cells in the electron microscope confirms the intracellular shifts in position of the Golgi apparatus. The results suggest that the Golgi apparatus shifts to the basal cell pole of the corneal epithelium in order to excrete connective tissue materials into the developing corneal stroma.
