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.

INTRODUCTION THE DECLINE AND FALL OF THE OLD ISLAMIC WORLD The rise of Islam is perhaps the most amazing event in human history. Springing from a land and a people alike previously negligible, Islam spread within a century over half the earth, shattering great empires, overthrowing long-established religions, remoulding the souls of races, and building up a whole new world—the world of Islam. The... more...

LETTER I. From the Architect. EVERY MAN SHOULD HAVE A HOME.   My Dear John: Now that your "ship" is at last approaching the harbor, I am confident your first demonstration in honor of its arrival will be building yourself a house; exchanging your charmingly good-for-nothing air-castle for an actual flesh-and-blood, matter-of-fact dwelling-house, two-storied and French-roofed it may be, with... more...

Certain apparently... more...

INTRODUCTION The Use of Punctuation.—Punctuation is a device for marking out the arrangement of a writer's ideas. Reading is thereby made easier than it otherwise would be.

An example will show this grouping... more...

Instinctively we perceive that there are within us powers and forces that we are... more...

PREFACE. We shall not imitate the invidious example of some authors, who think it necessary to destroy the edifices of others, in order to clear the way for their own. We have no peculiar system to support, and, consequently, we have no temptation to attack the theories of others; and we have chosen the title of Practical Education, to point out that we rely entirely upon practice and experience. To... more...

CHAPTER I Venetian painting in its prime differs altogether in character from that of every other part of Italy. The Venetian is the most marked and recognisable of all the schools; its singularity is such that a novice in art can easily, in a miscellaneous collection, sort out the works belonging to it, and added to this unique character is the position it occupies in the domain of art. Venice alone... more...

LECTURE I INTRODUCTORY WEDNESDAY, OCTOBER 25, 1916 I In the third book of the "Ethics", and in the second chapter, Aristotle, dealing with certain actions which, though bad in themselves, admit of pity and forgiveness because they were committed involuntarily, through ignorance, instances 'the man who did not know a subject was forbidden, like Aeschylus with the Mysteries,' and... more...

I. COMMERCIAL TERMS AND USAGES HERE is a distinction between the usage of the names commerce and business. The interchange of products and manufactured articles between countries, or even between different sections of the same country, is usually referred to as commerce. The term business refers more particularly to our dealings at home—that is, in our own town or city. Sometimes this name is used in... more...
