Excerpt from The Luminiferous Ether: I Its Relation to the Electron and to an Universal Interstellar Medium; II Its Relation to the Atom Presented in abstract at the twenty-second m. Merican Astronomical Society at Harvard College' Observatory, August 20, 1918, and is here reprinted in full from the new-church Review for October, 1918 (vol. XXV, pages 528 to It is an elaboration of a view put forth in my critique and appreciation of Swedenborg's Prin cipia which appeared in the same publication in April and July, 1913 (vol. XX, pages 161 to 197, and 392 to where a return to Swedenborg's scientific doctrine of a limited ether, and of light as consisting of discrete vibrating ether-particles, was advocated. The present paper includes much additional material, especially in respect to the connection of the ether with a fundamental electronic unit and the universal medium out of which both the electron and the ether-particle are sup posed to be formed. Incidentally, further details are included from my papers on the cause and limitation of gravitation which have not, as yet, been published elsewhere.
