    J out leaving any residue. Like paraffine it is un- affected by the strongest acids and alcalis, and like it also burns with a clear light, without smoke or odour. It has also the advantage of being slowly consumed, ‘These properties render it very suitable for lamps. Carbonic acid and water are the sole products of its combustion. It is insoluble both in cold and hot water. Alcohol is its best solvent: 33 parts of absolute alcohol at 63° F. dissolving 100 parts of eupione. With the assistance of heat, these two liquids unite in all proportions. Acetic ether dissolves about a third of its weight of eupione and sulphuret of carbon; and ether, naphtha, spirit of turpentine, oil of almonds, and olive oil, mingle easily with it in the cold. Eupione dissolves cam- phor, stearine and cetine, cholesterine, naphthaline, and paraffine, the action being much assisted by heat. Iodine is dissolved by it in the cold, with the production of violet vapours; and it also dis- solves chlorine and bromine. * These three sub- stances are expelled by heat, and the eupione is left unchanged. It dissolves caoutchouc with great rapidity. It is an excellent substance for preserv- ing potassium. It probably contains less carbon than parathne, but differs from it in no other respect. However, its exact composition is as yet only con- jectured. Kupione is more abundant in the animal than in
