This book contains an attempt to penetrate the mystery of space and time with the help of the most modern resources of scientific research. The treatment extends to the Infinite on one side and the Infinitesimal on the other, and seeks to annex a "first order" of each to the vast realm already surveyed and partly controlled by the human intellect. The main thesis of this work is that a universe constructed on a pattern not widely different from ours is encountered on a definite and measurable scale of smallness, and another on a correspondingly larger scale. To these universes the author gives the names Infra-World and Supra-World respectively. -"The Athenaeum." ; Vol. 1 & 2; 8vo 8" - 9" tall; 170 pages .
