Summary The parenchyma of the Harderian gland of the domestic duck consists of numerous tubular terminal portions, lined by a simple columnar epithelium. Its secretory surface is increased by intratubular folds. Within the cytoplasm of the epithelial cells secretory granules are observed. Polysaccharides of different nature are demonstrated. Strikingly, all centrally located cells contain a periodate reactive mucin. The successive administration of the PAS reaction and of Alcian Blue reveals the coexistence of acid and neutral mucins in the same cells. A metachromatic reaction of the mucosubstances at pH 1.0 was observed and the presence of acid sulfated groups in the Harderian gland, as demonstrated byAlcian Blue at pH 0.5, thereby confirmed. There was no glycogen reaction.
