Induction of Electric Currents. 6. About twenty-six feet of copper wire one twentieth of an inch in diameter were wound round a cylinder of wood as a helix, the different spires of which were prevented from touching by a thin interposed twine. This helix was covered with calico, and then a second wire applied in the same manner. In this way twelve helices were superposed, each containing an average... more...

The Hebrew Prophecies In the last chapter the opinion was expressed that the first books collected by Nehemiah, when he made up his "library," a century after the Exile, were the writings of the prophets. We studied the historical books first, because they stand first in the Hebrew Bible, and are there named the "Earlier Prophets;" but the probabilities are that the prophetical writings... more...

PREFACE. In this little book I have endeavoured to maintain the simplicity which is the ideal of this series. It is more difficult, however, to be simple in a topic which, even in its illustrations, demands of the reader more or less facility in the exploration of his own mind. I am persuaded that the attempt to make the matter of psychology more elementary than is here done, would only result in... more...

But besides this, it was well known that the current grammarians, and the critical philologists, had long ceased to write alike upon the English, or indeed upon any other, language. For this reason the sphere of the work became enlarged; so that, on many occasions, general principles had to be enounced, fresh terms to be defined, and old classifications to be remodelled. This introduced extraneous... more...

PREFACE It seems eminently fitting and proper in this year, the fiftieth anniversary of the Proclamation of Emancipation that the Negro should give pause and look around him at the things which he has done, those which he might have done, and those which he intends to do. We pause, just at the beginning of another half century, taking stock of past achievements, present conditions, future... more...

Newspaper advertising is to business, what hands are to a clock. It is a direct and certain means of letting the public know what you are doing. In these days of intense and vigilant commercial contest, a dealer who does not advertise is like a clock that has no hands. He has no way of recording his movements. He can no more expect a twentieth century success with nineteenth century methods, than he... more...

CHAPTER 2.   Infantry Drill Regulations. The greatest lesson of the present war is that the keynote of success is discipline. In trenches the direct control of the men is even less than in extended order in open warfare, and only thoroughly disciplined troops with a trusted leader can hope to succeed. The successful officer will show anger or irritation only in rare cases, and then by design: he will... more...

When travelling lately through the Simplon—one of the great Alpine passes leading from Switzerland into Italy—I observed, close by the roadside, at regular distances, a number of plain, square buildings. On these (sometimes over the doorway, sometimes on the side) were inscribed the words—“Refuge No. 1,” “Refuge No. 2,” “Refuge No. 3,” &c. I think there were twenty altogether. I... more...

INTRODUCTION. The importance of every woman having a thorough knowledge of domestic economy cannot be too strongly insisted on. The false refinement which, of late years, has considered an acquaintance with domestic matters to be only suitable for servants, has been fraught with the most disastrous consequences. This may seem strong language, but it is not too strong. All sanitary reformers know well... more...

early beloved: we are gathered together here in the sight of God, and in the presence of these witnesses, to join together this man and this woman in holy Matrimony; which is an honorable estate, instituted of God in the time of man's innocency, signifying unto us the mystical union that exists between Christ and his Church; which holy estate Christ adorned and beautified with his presence, and... more...
