The principles of light and color: including among other things the harmonic laws of the universe, the etherio-atomic philosophy of force, chromo chemistry, chromo therapeutics, and the general philosophy of the fine forces, together with numerous discoveries and practical applications .. . carbonic oxide (CO), on receiving a largershare of oxygen, assumes the more intense form ofcarbonic acid (C02), and becoming ignited andvolatile with heat, spreads out into the luminousportion c. The very thin, almost invisible, bluishenvelope e, c, is caused by the inward rush ofthe oxygen as it seeks its affinitive uprising hydro-gen. This may be seen best by viewing a flame inits narrow direction. If the upper and more luminous part ofthe flame should be hidden by the hand or some other object,the exquisite blue, merging into indigo and violet, may be seenvery distinctly. The same will appear in the flames made byburning wood, coal, paper, matches, and other objects, where theflame joins the lower part of these objects, as no eliminationof luminelles can take place without the electrical flow. 3. In the case of magnesium light, particles of magnesia (MgO)constitute the luminelles, in the calcium light, particles of lime(CaO), in burning strontium, particles of strontia (SrO), whose.

As I have said before, how-ever, carbon is by far the most common basis of luminelles for prac-tical illuminating purposes. 4. WJiy do the luminelles of a flame when brought into contactwith a person cause so much more pain than the usual atmos-pheric luminelles as ignited by the sunlight ? Because they arecoarser, far more condensed, and emit a ruder grade of will also explain why the luminelles of an ordinary flame ortorch remain dark in the center for a moment, while those of
