[14] NOTE.--It should be understood that a dynamo does not generate electricity, for if it were only the quantity of electricity that is desired, it would be of no use, as the earth may be regarded as a vast reservoir of electricity. However, electricity without pressure is incapable of doing work, hence a dynamo, or so-called “generator,” is necessary to create an electromotive force by electromagnetic induction in order to cause the current to flow against the resistance of the circuit and do useful work. * * * * * TRANSCRIBER’S AMENDMENTS Transcriber’s Note: Blank pages have been deleted. Some illustrations may have been moved. Notes at the bottom of pages in the text were converted to footnotes and footnote tags were added to the text itself. The footnotes are now located prior to this section. When the author’s preference can be determined, we have rendered consistent on a per-word-pair basis the hyphenation or spacing of such pairs when repeated in the same grammatical context. The publisher’s inadvertent omissions of important punctuation have been corrected. Duplicative front matter has been removed. The following list indicates any additional changes. The page number represents that of the original publication and applies in this etext except for footnotes and illustrations since they may have been moved.
