same force, and appear as comets coming to the centres of light and heat, there to be exposed for a short period to a process of expansion, moulding, and preparation for renewed concentration on their return to the cold distant regions of their nativity? Or, is it beyond possibility that these wayward things, after having passed through many phases and assumed many conditions, should at length become formally attached to individual systems, take up distinct places within their bounds, and settle down into steady-going decorous planets, furnished and endowed with all the capabilities for supporting new existences called into being by the breath of life from the dust of the ground? In conclusion, as the satellites proceeding in double revolution round the sun and planets become typical of the great sun with its attendant train of orbs, being borne along with other systems by the power of some greater luminary in the far distance-planet, sun, and system occupying positions of arrangement relatively to each other by virtue of the nature and circumstances of their construction, and moving in their several spheres with the truest accuracy and precision. So these again typify orbs of greater and greater power, and system upon system revolving and singing the hymn of praise in grander and yet grander revolution, till Heaven itself broadens out into the boundless universe, and man loves to fancy that as science advances in knowledge along the great chain of causation, its responses will approach nearer and nearer to the teachings of revealed religion, and finally attain its full fruition in the perfect light of that Infinite One, from whom proceeds all the energy, beauty, and order by which the worlds are created and governed. As this analysis of nitrogen contains the elements of carbonic oxide and olefiant gas, for C, H ̧ 0 = €0 + €, H1, let us take these substances and suppose them to be united in nitrogen in accordance with chemical laws by a double process of combination, thus: On the same principles cyanogen shows itself to be a progressive combination, richer in carbon than nitrogen. It is known to be a compound of € + N 44 N, and to have a gas specific gravity of 26. Adding 4 to the components of 4 N, cyanogen equals Є, H, O, probably united in the following 4 Hypothetical decomposition of nitrogen in respiration, and its recomposition with the free oxygen of |
