Dynamo-Electric Machinery

Abstract

PROF. SILVANUS P. THOMPSON has undertaken the task of filling up a most important want in our scientific and technical literature; and he is to be congratulated and warmly thanked for the manner in which the task has been performed. Of the want of a scientific and practical work on dynamo-electric machinery there can be no question. The subject is at present exciting more general attention than was, perhaps, ever before given to any invention, not even excluding the steamengine or the electric telegraph. The electric light effects are fascinating to a degree; and in these days of exhibitions and displays the natural interest in one of the most beautiful inventions has been fostered even beyond that which is natural: while speculation and even the promises of “electric light in our homes” have led to excitement which has been equally disastrous to the hopes of the many and to the progress of electric lighting itself. We are now entering it is to be hoped, or indeed have already entered, upon a more satisfactory state of things, in which hard and steady work and careful scientific investigation of every point on which efficiency and advantage in electric lighting depends will quietly bring forth an appropriate reward; and will gradually sweep away the painful impressions left by the failures of would-be electricians and of bubble companies.
