Excerpt from The Sun: Ruler, Fire, Light, and Life of the Planetary System When I had completed my treatise on Saturn and its System, I formed the design of preparing a separate treatise on each of the planets Mars and Jupiter, and then another and larger treatise on the Sun. Circum stances, which it is needless to particularise, prevented me from carrying out this design at that time, and indeed threatened to withdraw my attention altogether from scientific pursuits. That my plans, though delayed, have not been lost sight of during the last four years, is evidenced by the appearance of many papers of mine on Mars, Jupiter, and the Sun, in several quarterly, monthly, and weekly journals. These, if collected, would of themselves suffice to form volumes of no inconsiderable dimensions on these several orbs; while my Other Worlds than Ours presents a sort of summary of my researches on these and other astronomical subjects. But it is only quite recently that I have been able to resume my original design. The delay has not been without its advantages, however. A work on the Sun has at the present time a far greater interest than it would have had four years since while I have been able to obtain a much wider and more complete view of the subject than I should probably have thought necessary had I completed the work at that time.
