The Earth’s Beginning are lectures which were delivered in the Royal Institution of Great Britain. It considers the majestic subject of the evolution of the solar system of which our earth forms a part. The nebular theory discloses the beginning of this earth itself. It shows how the foundations of this solid earth have been laid, and how it is that we have land to tread on and air to breathe. But the subject has a scope far wider than merely in its relation to our earth.
