About this Item
[1895 / 1900] Volume LX, May - October, 1900, three-quarter leather and marbled boards, raised bands at spine, light general wear-only, overall a clean, bright copy, but ex-library with small catalog number at spine tail, pocket and small catalog bar code at rear pastedown, and remnants of a borrower's slip at rear fly, contents very clean and bright, and Volume XLIX, November, 1894 - April, 1895, in three-quarter black leather and black pebbled cloth, gilt titles and decorations and raised bands at spine, very clean and bright, inside and out, but also an ex-library copy, with small bookplate at front pastedown, a blind perforation stamp at title-page, and white ink catalog number at spine tail, and ink note at top edge which identifies the volume number, else very clean and bright. First piece is 37pp, printed in double columns, and illustrated after the author's electrical experiments with 12 photographs now published for the first time according to the editor. Includes an editorial note on Tesla at page 312. Illustrations include burning the nitrogen of the atmosphere, a diagram of the three ways of increasing human energy, the first practical Telautomaton, an experiment to illustrate the supplying of electrical energy through a single wire without return, the experiment to illustrate the transmission of electrical energy through the earth without wire, a photographic view of the coils responding to electrical oscillations, a view of the essential parts of the electrical oscillator used in the experiment, an experiment to illustrate an inductive effect of an electrical oscillator of great power, the experiment to illustrate the capacity of the oscillator for producing electrical explosions, an experiment to illustrate the capacity of the oscillator for creating a great electrical movement, a photographic view of an experiment to illustrate the effect of an electrical oscillator delivering energy at a rate of seventy-five thousand horse-power, and small diagrams of wireless telegraphy mechanically illustrated, and obtaining energy from the ambient medium. The second piece - by Martin - is 18-pages, printed in double columns, illustrated with 14 photographs and a diagram of the working parts of an early form of Tesla oscillator. This is the author's follow-up piece after the release of his full-length title -- now scarce, and very expensive -- INVENTIONS, RESEARCHES AND WRITINGS OF NIKOLA TESLA WITH SPECIAL REFERENCE TO HIS WORK IN POLYPHASE CURRENTS AND HIGH POTENTIAL LIGHTING, published by The Electrical Engineer, NY, 1894. Per the current Editor, the photographs reproduced in the present article were taken under special direction of the inventor by Tonnele & Company. Photos include the latest form of Tesla oscillator combining in one mechanism dynamo and steam-engine, the first photograph ever taken by phosphorescent light, January, 1894, a phosphograph of Mark Twain taken in Tesla's laboratory, three phosphorescent bulbs under test for Actinic value photographed by their own light, Tesla tubes of different forms in which light is obtained without filament or combustion and photographed by their own light, an experiment showing the play of electric sparks between condenser plates, an experiment showing the lighting up of an ordinary incandescent lamp at a distance through the influence of electrified ether waves, an experiment illustrating the lighting of an incandescent lamp in free space by induction from coil below, a similar experiment illustrating the phenomenon of impedance, an experiment illustrating a high-tension current being passed through the body before it lights the lamps, the effect of electrical discharge from the earth by Tesla coil, and a Tesla coil for ascertaining and discharging the electricity of the earth. At the end of the article is a poem, In Tesla's Laboratory, by Robert Underwood Johnson. Both titles very scarce, only exceeded in scarcity by the single issues.
