The Vailan or annular theory: A synopsis of Prof. I. N. Vail's argument in support of the claim that this Earth once possessed a Saturn-like system of rings, a classical book, has been considered important throughout the human history, and so that this work is never forgotten we at Alpha Editions have made efforts in its preservation by republishing this book in a modern format for present and future generations. This whole book has been reformatted, retyped and designed. These books are not made of scanned copies of their original work and hence the text is clear and readable.
