• The fine structures of the epithelial cells of the guinea pig Eustachian tube were studied with a newly developed scanning electron microscopy technique. The intracellular organelles of the ciliated cells and the goblet cells could be observed threedimensionally, and the topographic relationships were analyzed. In both cells, the mitochondria were spherical or cask shaped and their cristae were tubular.The rough endoplasmic reticulum was reticular, spreading out in the cytoplasm. The goblet cells contained a well-developed Golgi apparatus with stacks consisting of five to seven cisternae. The outermost part of the cisterna at the cis-face was fenestrated. This fenestrated cisterna was continuous with the neighboring Golgi stack. The Golgi apparatus of the ciliated cells was not so well developed, but a GERL-system was probably present.
