Occurrence in Plants.—Aleurone.—It is only in the old and virtually dead parts of a living plant that albu- minoids are ever wanting. In the young and growing organs they are abundant, and exist dissolved in the sap or juices. They are especially abundant in seeds, and here they are often deposited in an organized form, chiefly. ooooa.
