(1) The standard silver and osmium techniques show a typical Golgi apparatus in the epithelial cells of the stomach and intestine of the leech, Glossiphonia complanata.
(2) Histochemical studies reveal the presence of lipoids in the Golgi region of these cells. In the stomach, part, at least, is lipine. (In the intestinal cells, the rest of the cytoplasm contains much lipine, but the Golgi apparatus little or none that can be shown by the method used.)
(3) The Golgi apparatus in these cells appears to consist of rows of nonlipoidal spheres, each with a lipoid coat. In the stomach, this coat contains lipine.
