The processes which have to be gone through in the condensation of this nebular universe of incandescent matter are still under discussion. But much is known of them. Either the centra] mass (or Sun) was formed first, or the revolving planetary bodies. There are reasons, arising from recent observations, for supposing that either may have been the case. But in any case a series of consecutive condensations in the rarer ne¬ bulous material took place, leading up to the orderly and consecutive evolutions which we now know for certain to have occurred in our globe. It is the nature of this comparatively sure knowledge and the mode of its ascertainment that we have to consider. It has been established with¬ out question that within our system, and, as we may infer, within the Universe, no loss occurs in either Matter or in Energy. Matter is in its combinations ever undergoing change. Energy takes new forms and development.
