AB -  In spectroscopic and other researches it is often necessary to employ a light of definite color for considerable periods of time. A flame of pure and intense color can be maintained for hours by means of the simple apparatus here described and illustrated, which can be made of materials to be found in every laboratory. APPARATUS FOR THE PRODUCTION OF COLORED FLAMES. To the gas pipe is connected a bent glass tube (B) which passes over the rim of a beaker of Bohemian glass, follows the inner surface of the beaker to the center of the bottom, and thence rises vertically, nearly to the top of the vessel. The end of this tube is surrounded by a larger glass tube, the upper end of which is tapered and enters, above the rim of the beaker, the bottom of a wide porcelain tube, which serves as a Bunsen burner. A wire, wound in a helix around the small glass tube, and then around the larger tube which surrounds it, forms the cathode of a galvanic battery, of which a rod of carbon (F) forms the anode. The beaker is filled very nearly to the top of the small glass
