Langley writes: 'The cells of mucous salivary glands I have previously described as consisting of a framework or network, containing in its spaces hyaline substance and granules. I have also mentioned that during secretion the granules disappear from the outer portions of the cells. A similar disappearance of granules has been found by Biedermann to occur in the cells of the mucous glands of the tongue of the frog. The granules of the mucous salivary glands are rendered very distinct by irrigating a mounted specimen of a fresh gland with moderately dilute solutions of neutral or alkaline salts.'
