Excerpt from ElectricityCare has been taken, as far as possible in an elementary work, to include the more recent inventions and methods. The British Association unit of resistance is adopted in the section on Galvanism, and a chapter is afterwards devoted to the method of determining it, and to the system of measurement of the current elements in electro magnetic units. The French and German equivalent words are given where the same terms are not used. These equivalents frequently describe a piece of apparatus, or an electric action, from another point of view than that from which the English words are taken. Moreover, many of them, either in themselves or in their transla tions, have found their way into the English language, and they thus save the necessity of giving synonyms. A historical sketch is given at the end of each section or chapter, in which the author and the date of every important discovery or invention are carefully noted.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
