DIAMETER (from the Gr. διά, through, μέτρον, measure), in geometry, a line passing through the centre of a circle or conic section and terminated by the curve; the “principal diameters” of the ellipse and hyperbola coincide with the “axes” and are at right angles; “conjugate diameters” are such that each bisects chords parallel to the other. The diameter of a quadric... more...

CHAPTER I MY EAGLE The soft summer wind stirs the redwoods, and Wild-Water ripples sweet cadences over its mossy stones. There are butterflies in the sunshine, and from everywhere arises the drowsy hum of bees. It is so quiet and peaceful, and I sit here, and ponder, and am restless. It is the quiet that makes me restless. It seems unreal. All the world is quiet, but it is the quiet before the storm. I... more...

INTRODUCTION. Gilbert White’s home in the quiet Hampshire village of Selborne is an old family house that has grown by additions, and has roofs of nature’s colouring, and creeping plants on walls that have not been driven by scarcity of ground to mount into the air.  The house is larger, by a wing, now than when White lived in it.  A little wooded park, that belongs to it, extends to a steep... more...

CHAPTER I A TALK ABOUT BIOGRAPHY No doubt most of you think biography dull reading. You would much rather sit down with a good story. But have you ever thought what a story is? It is nothing but a bit of make-believe biography. Let us see, in the first place, just what biography means. It is formed from two Greek words, "bios," meaning life, and "graphein," meaning to write:... more...

CHAPTER I INTRODUCTION The indebtedness of German culture to other peoples has been the theme of much painstaking investigation. The history of German literature is, in large measure, the story of its successive periods of connection with the literatures of other lands, and hence scholars have sought with industry and insight to bound and explain such literary inter-relations. The latter half of the... more...

CHAPTER I THE FEAST It was at Megara, a suburb of Carthage, in the gardens of Hamilcar. The soldiers whom he had commanded in Sicily were having a great feast to celebrate the anniversary of the battle of Eryx, and as the master was away, and they were numerous, they ate and drank with perfect freedom. The captains, who wore bronze cothurni, had placed themselves in the central path, beneath a... more...

The so-called Countess Piccolomini was a fine example of the adventurers. She was young, tall, well-made, had eyes full of fire, and skin of a dazzling whiteness; not, however, that natural whiteness which delights those who know the value of a satin skin and rose petals, but rather that artificial fairness which is commonly to be seen at Rome on the faces of courtezans, and which disgusts those who... more...

CANON ALBERIC'S SCRAP-BOOK St Bertrand de Comminges is a decayed town on the spurs of the Pyrenees, not very far from Toulouse, and still nearer to Bagnères-de-Luchon. It was the site of a bishopric until the Revolution, and has a cathedral which is visited by a certain number of tourists. In the spring of 1883 an Englishman arrived at this old-world place—I can hardly dignify it with the name... more...

Frederick Braun, M.D., Ph.D., various other Ds, pushed his slightly crooked horn-rims back on his nose and looked up at the two-story wooden house. There was a small lawn before it, moderately cared for, and one tree. There was the usual porch furniture, and the house was going to need painting in another six months or so, but not quite yet. There was a three-year-old hover car parked at the curb of a... more...
