Henry Raymond Rogers New and Original Theories of the Great Physical Forces

The sun's position in the great field of energy is daily becoming more exalted in the estimation of philosophic minds. His labors are being revealed to us with a distinctness never before conceived. He it is that stored the coal in the bosom of the earth, and piled up the polar ice. He it is that aids the chemist, drives the engine, ripens the harvest, dispenses life and health.
The study of the sun and solar physics, therefore, must be essential to the right understanding of whatever we observe to take place at the earth. Sun and earth are united in indissoluble bonds.

Henry Raymond Rogers New and Original Theories of the Great Physical Forces

Ignorance of the sun, of its character, and of the methods by which its functions are performed, must be confessed; notwithstanding all the more recent unfoldings and imaginings of scientists, regarding the great orb. But yet we are very hopeful of vast increase in our solar knowledge; not alone, or chiefly, by new observations, or discoveries, but quite as much by new interpretations of old, long observed phenomena. The ground of hopefulness lies in the belief that a grand unity underlies, and binds together in one, all Physical Forces, as well in earth and sun.

And, indeed, the sun possesses within himself alone no element of supply of his own needed light and heat; and in his immensity and power is even dependent upon the circling orbs, for the quantity of each which is indispensable to a condition of habitation.
The bodies of the planets are in like manner invisible; we behold but the illumined atmosphere of each sphere. Thus the moon and planets, to be visible, must possess atmospheres.
