1. Unusual crystalloids were found in the cytoplam of mice lung cells.
2. Most of the crystalloids are rods or ellipsoids. They are surrounded by a layer of fine granules and are sheathed with an outer membrane. They have the size about two to four times longer than the mitochondria.
3. It is suggested that the crystalloid may be formed by the smoothwalled endoplasmic reticulum and their contents are phagocytic or secretion products of the cell.
