[Transcriber's Notes]

Obvious spelling errors have been corrected. I have not reconciled the variety of spellings of names and other words. Obvious factual errors, typographical errors, discoveries made after 1892, and contemporary (2008) theories and use of words are noted in the text within square brackets. I have not researched and checked every assertion by the author.

This book was published 5 years before discovery of the electron. See the labored and completely inaccurate explanations of aurora and "energy, atomic". The author and his contemporaries were like fifteenth century sailors. They had a good idea of their latitude and direction (Ampere, Kirkoff, Maxwell, Gauss, Faraday, Edison, …), but only the vaguest notion of their longitude (nuclear structure, electrons, ions). Altitude (special relativity, quantum theory) was not even imagined.

Some relevant dates: Franklin's Kite 1752 Faraday's Law of Induction 1831 Maxwell's Equations 1861 Edison's Phonograph 1877 Edison's light bulb 1879 Edison's first DC power station 1882 Michelson Morley experiment disproving ether 1887 Hertz demonstrates radio waves 1888 Westinghouse first AC power station 1891 This book 1892 Discovery of the electron 1897 Marconi radio signals cross the English Channel 1897 First Vacuum Tube 1904 Special Relativity, photo electric effect explained with photons 1905 General Relativity: space time dilation and curvature 1915 Confirmation of general relativity's prediction of the deflection of starlight by the Sun 1919 Discovery of the proton 1920 Quantum theory 1926 Discovery of neutron 1932 First transistor 1947 Soviet satellite Luna measures solar wind 1959 Edward M. Purcell explains magnetism with special relativity 1963

Purcell's explanation of magnetism as a result of Lorentz contraction of space along the direction of a current is a welcome relief from the convoluted descriptions in this book.

Mathematical notation is rendered using "programming" notation. ^ Power Exponential; A^3 means "A cubed" Multiply / Divide Add Subtract ( ) Precedence Perform before enclosing expression 2E6 Scientific Notation (2,000,000)

A 4.452 X 10^12 X t

is rendered as

A / ( 4.452E12 t )

Where the rendering of a mathematical expression is in doubt, an image of the original text is included.

Here are some definitions absent from the text.

Foucault currents. Eddy currents.

inspissate To thicken, as by evaporation.

riband Ribbon.

sapotaceous Order Sapotace[ae] of trees and shrubs, including the star apple, the Lucuma, or natural marmalade tree, the gutta percha tree (Isonandra), and the India mahwa, as well as the sapodilla, or sapota, after which the order is named.
