Soft cover. Condition: Good. S. Tolver Preston, "On some Dynamical Conditions applicable to Le Sage's Theory of Gravitation" in: "London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science", Volume IV, Fifth Series, September 1877, pp 161-240 with the Preston on pp 206-213. AND WITH: S. Tolver Preston, "On Le Sage's Theory of Gravitation" (part II) pp364-375 in the issue of pp 321-400 in the November 1877 issue of the Philosophical Magazine.[++] Both are full issues and are extracted neatly from a larger bound volume. [++] "Preston is known for his works (1875 1894) on the kinetic theory of gases and his attempts to combine this theory with Le Sage's theory of gravitation. In his book Physics of the Ether (1875), he postulated that, if matter is subdivided into "ether particles", they would travel at the speed of light and represent an enormous amount of energy. In this way, one grain of matter would contain energy equal to 1000 million foot-tons. Preston also seemed to be the first (1885) to recognize the redundancy of Michael Faraday's explanation of electromagnetic induction. Einstein recognized a similar problem in his paper On the electrodynamics of moving bodies (1905)." [++] Also in the November issue: Eugen Goldstein. "On Electric Discharges through Rarified Gases" Volume IV, Fifth Series, November 1877, 321-400, with the Goldstein on pp353-363. The Goldestein paper is the translation into English of his paper from May 1876 "Vorläufige Mittheilungen über elektrische Entladungen in verdünnten Gasen"); and with Reitlinger and von Urbanitzki, "On Some remarkable Phenomena in Geissler Tubes", which is a short note on page 240, which Golstein uses in his research and references in this article. It seems to me that what he is discussing is the Cathode Ray ("kathodenstrahlen"), which he names in 1876 (and which had been known since 1869 [Parkinson, Breakthroughs] though it seems as though he does not use the term here. ("Eugen Goldstein was an early investigator of discharge tubes, the discoverer of anode rays, and is sometimes credited with the discovery of the proton.In the 1870s Goldstein undertook his own investigations of discharge tubes, and named the light emissions studied by others Kathodenstrahlen, or cathode rays. He discovered several important properties of cathode rays, which contributed to their later identification as the first subatomic particle, the electron."--Wiki.
