English Grammar is divided into four parts-Orthography, Etymology, Syntax, and Prosody; and as these are points that a good grammarian always stands upon, he, particularly when a pedant, and consequently somewhat flat, may very properly be compared to a table. Latinised English, or Fine English, sometimes assumes the character of Comic English, especially when applied to the purposes of common discourse; as "Extinguish the luminary," "Agitate the coramunicator," "Are your corporeal functions ...

It falls into this difficulty without any fault of its own. It begins with principles, which cannot be dispensed with in the field of experience, and the truth and sufficiency of which are, at the same time, insured by experience. With these principles it rises, in obedience to the laws of its own nature, to ever higher and more remote conditions.

But it quickly discovers that, in this way, its labours must remain ever incomplete, because new questions never cease to present themselves; and t...

Philosophiæ Naturalis Principia Mathematica (Latin for Mathematical Principles of Natural Philosophy), often referred to as simply the Principia, is a work in three books by Isaac Newton, in Latin, first published 5 July 1687. After annotating and correcting his personal copy of the first edition, Newton published two further editions, in 1713 and 1726. The Principia states Newton's laws of motion, forming the foundation of classical mechanics; Newton's law of universal gravitation; and a de...

As the work is divided into chapters, the subjects of which are complete in themselves, the pupil may commence the study of the structure, use, and laws of the several parts of which the human system is composed, by selecting such chapters as fancy or utility may dictate, without reference to their present arrangement,—as well commence with the chapter on the digestive organs as on the bones.

The acquisition of a correct pronunciation of the technical words is of great importance, both in r...

THIS little book purports to serve as an introduction to the great problems of space, time and motion. The inquiries it is concerned with are very old. Men have been forming ideas concerning space and time since times immemorial, and curiously enough, have been writing and fighting about these things with the greatest interest, even fanaticism.

This has been a strange strife, indeed, having little to do with economic necessities; it has always dealt with abstract things, far removed from our ...

The year 146 B.C. was an annus mirabilis in the development of Roman dominion. Of course it had long been a foregone conclusion that Carthage and Corinth must fall before her, but the actual time of their overthrow was made all the more striking by the fact that both cities perished in the same year, and that both were visited by the same fate.

I have attempted in this story to group some picturesque inci-dents round the person of a young Greek who struggles in vain to resist the destiny of t...

LUIS AGUIRRE had been living in Gibraltar for about a month. He had arrived with the intention of sailing at once upon a vessel bound for Oceanica, where he was to assume his post as a consul to Australia. It was the first important voyage of his diplomatic career. Up to that time he had served in Madrid, in the offices of the Ministry, or in various consulates of southern France, elegant summery places where for half the year life was a continuous holiday.

THE SON of a family that had been...

IN ancient times, when the city of Rome was at the height of its power and splendor, it was the custom, as it is in fact now with the inhabitants of wealthy capitals, for the principal families to possess, in addition to their city residences, rural villas for summer retreats, which they built in picturesque situations, at a little distance from the city, sometimes in the interior of the country, and sometimes upon the seashore. There were many attractive places of resort of this nature in th...

IT was Christmas Eve. I remember it just as if it was yesterday. The Colonel had been pretending not to notice it, but when Drinkwater Torm knocked over both the great candlesticks, and in his attempt to pick them up lurched over himself and fell sprawling on the floor, he yelled at him. Torm pulled himself together, and began an explanation, in which the point was that he had not "teched a drap in Gord knows how long," but the Colonel cut him short.

"Get out of the room, you drunken vagabond...

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity.

He continued to deal with prob...
