On studying the changes which occur in a living serous gland, Langleyfound that, during rest, the substance of the cells of the parotid is per-vaded by fine granules, which are so numerous as to obscure the nucleus,while the outlines of the cells are indistinct. No lumen is visible inthe acini during activity, the granules disappear from the outer zone ofthe cells, the cells themselves becoming more distinct and smaller. After.
