After this brief pointer as to how these gigantic formative and levitative forces can be made use of in the national economy, it should also be mentioned that these 'original' tractive and transportive forces can be applied to the silent, odourless, smokeless, toxic-emission-free propulsion of all types of machine, all forms of conveyance on land, on water and in the air at any desired speed and at negligible cost, for in such machines, instead of resistance, the power increases by the square of the velocity. Now devoid of foundations, the crowning law of fire-spitting technology will therefore collapse upon itself.

The primitive laws of any science should be capable of succinct statement, but in combination with others they become more complex and delicate, and error is proved if in the developments they do not echo each other. If, therefore, musical harmonies are correctly gained, the same laws will develope harmonies of colour, and will agree with the colours of the rainbow, the circle of which is divided by the horizon. All who are interested in the laws which regulate these two sciences will doubtless know the interesting lectures delivered by W. F. Barrett (Professor of Experimental Physics in the Royal College of Science, Dublin), and the article written by him and published in the Quarterly Journal of Science, January, 1870, entitled "Light and Sound; an examination of their reputed analogy, showing the oneness of colour and music as a physical basis." I will quote shortly from the latter for the benefit of those who may not have met with it. "The question arises, Has all this æsthetic oneness of colour and music any physical foundation, over and above the general analogy we have so far traced between light and sound? We believe the following considerations will show, not only that it has some foundation, but that the analogy is far more wonderful than has hitherto been [Harmonies of Tones and Colours, On Colours as Developed by the same Laws as Musical Harmonies1, page 18]
"Science has a foundation, and so has Religion: let them unite their foundations, and the basis will be broader, and they will be two compartments of one great fabric reared to the glory of God."—M'Cosh. [Harmonies of Tones and Colours, Reflections on the Scheme3, page 45]
