6. ([Page 36.]) M. Maiche, in Les Mondes, propounds the theory, reached after numerous experiments, that water is simply hydrogen plus electricity, or oxygen minus electricity, or, in other words, that normal electrified hydrogen constitutes water, and that normal diselectrified oxygen produces the same; or that hydrogen, oxygen, and water are precisely the same, differing only in degree of electrification.

7. ([Page 41.]) "The sun, as the main source of heat and light, must be able to call forth and animate magnetic forces on our planet."—Humboldt.
"It is an incontestable fact that the sun exercises an action upon the magnetic phenomena which are manifested upon our globe."—Secchi.
"What is certain is, that there ought to be, between the sun and planets, a means of communication of force, and the transmission of movement."—Ibid.
"The central body may, as a powerful source of heat, excite magnetic activity on our planet."—Humboldt.
