THE THREE HYPOTHESES RESPECTING THE HISTORY OF NATURE. We live in and form part of a system of things of immense diversity and perplexity, which we call Nature; and it is a matter of the deepest interest to all of us that we should form just conceptions of the constitution of that system and of its past history. With relation to this universe, man is, in extent, little more than a mathematical point;... more...

Page 3 RECREATIONS IN ASTRONOMY. I. CREATIVE PROCESSES. During all the ages there has been one bright and glittering page of loftiest wisdom unrolled before the eye of man. That this page may be read in every part, man's whole world turns him before it. This motion apparently changes the eternally stable stars into a moving panorama, but it is only so in appearance. The sky is a vast, immovable... more...

CHAPTER I. INTRODUCTORY. The Sun. The sun's position in the great field of energy is daily becoming more exalted in the estimation of philosophic minds. His labors are being revealed to us with a distinctness never before conceived. He it is that stored the coal in the bosom of the earth, and piled up the polar ice. He it is that aids the chemist, drives the engine, ripens the harvest, dispenses... more...

Some thousands of years ago there was a city in Mesopotamia called Surippak. One night a strange dream came to a dweller therein, whose name, if rightly reported, was Hasisadra. The dream foretold the speedy coming of a great flood; and it warned Hasisadra to lose no time in building a ship, in which, when notice was given, he, his family and friends, with their domestic animals and a collection of... more...

COAL AND COAL-MINES. There are few subjects of more importance, and few less known or thought about, than our coal-mines. Coal is one of our greatest blessings, and certainly one originating cause of England's greatness and wealth. It has given us a power over other nations, and vast sums of money are yearly brought to our country from abroad in exchange for the coal we send. Nearly £17,000,000... more...

CHAPTER I THE AIMS OF NATURE STUDY Nature Study means primarily the study of natural things and preferably of living things. Like all other subjects, it must justify its position on the school curriculum by proving its power to equip the pupil for the responsibilities of citizenship. That citizen is best prepared for life who lives in most sympathetic and intelligent relation to his environment, and it... more...

IN the last Lecture I endeavoured to prove to you that, while, as a general rule, organic beings tend to reproduce their kind, there is in them, also, a constantly recurring tendency to vary—to vary to a greater or to a less extent. Such a variety, I pointed out to you, might arise from causes which we do not understand; we therefore called it spontaneous; and it might come into existence as a... more...

CHAPTER I. APPARENT ATTRIBUTES OF THE STARS. 1. Our knowledge of the stars is based on their apparent attributes, obtained from the astronomical observations. The object of astronomy is to deduce herefrom the real or absolute attributes of the stars, which are their position in space, their movement, and their physical nature. The apparent attributes of the stars are studied by the aid of their... more...

PREFACE. My warmest thanks are due to Mr. Francis Darwin, to Mr. E. B. Poulton (whose interest in the subject here discussed is shown by his share in the translation of Weismann's Essays on Heredity), and to Professor Romanes, for the help afforded by their kindly suggestions and criticisms, and for the advice and recommendation under which this essay is now published. Encouragement from Mr.... more...

CHAPTER I A DAY IN THE OBERLAND I am writing in early September from Interlaken, one of the loveliest spots in Europe when blessed with a full blaze of sunlight and only a few high-floating clouds, but absolutely detestable in dull, rainy weather, losing its beauty as the fairy scenes of a theatre do when viewed by dreary daylight. It is the case of the little girl of whom it is recorded that "When... more...
