Book excerpt: Excerpt from Electricity, Magnetism, and Electric Telegraphy: A Practical Guide and Hand-Book of General Information for Electrical Students, Operators, and Inspectors Electricity is pre-eminently a science of the nineteenth century. We cannot even at this late day say that we know what electricity is; and within a comparatively recent period even its manifestations and phenomena were familiar to a relatively small class, composed chiefly of college professors and scientific lecturers. Few of the class which was entrusted with the management of its practical applications - viz., telegraphers and electro metallurgists - had any scientific knowledge of its laws, or, in fact, anything but a mechanical and empirical knowledge of the manipulation of the telegraph instrument and the electrolyzing battery. This state of things has, however, passed away, and electricity has become the favorite, most promising, and most important scientific study of that section of the human race which, under the title of inventor, aspires to achieve fame or fortune, or both, by the work of its own brains. During the last decade we have seen such wonderful developments in electricity and electro-magnetism that while on the one hand we can scarcely conceive of anything which cannot be done by these agencies, on the other hand we are almost compelled to believe that there is little more left for electricity to achieve.
