Chapter One: Education as a Necessity of Life 1. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal.

Never does the stone attempt to... more...

Induction of Electric Currents. 6.

Public opinion is the ultimate force that controls... more...

CHAPTER I INTRODUCTION This book is intended not to raise fears but to record facts. We wish to describe with pen and pencil those features of England which are gradually disappearing, and to preserve the memory of them. It may be said that we have begun our quest too late; that so much has already vanished that it is hardly worth while to record what is left. Although much has gone, there is still,... more...
