ON THE RECEPTION OF THE 'ORIGIN OF SPECIES.' To the present generation, that is to say, the people a few years on the hither and thither side of thirty, the name of Charles Darwin stands alongside of those of Isaac Newton and Michael Faraday; and, like them, calls up the grand ideal of a searcher after truth and interpreter of Nature. They think of him who bore it as a rare combination of genius, industry, and unswerving veracity, who earned his... more...

CHAPTER I. . . . The justification of all persons who have freed themselves from toil is now founded on experimental, positive science.  The scientific theory is as follows:— “For the study of the laws of life of human societies, there exists but one indubitable method,—the positive, experimental, critical method “Only sociology, founded on biology, founded on all the positive sciences, can give us the laws of... 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 is the primary aim of Nature Study to... more...

MR. DARWIN'S long-standing and well-earned scientific eminence probably renders him indifferent to that social notoriety which passes by the name of success; but if the calm spirit of the philosopher have not yet wholly superseded the ambition and the vanity of the carnal man within him, he must be well satisfied with the results of his venture in publishing the 'Origin of Species'. Overflowing the narrow bounds of purely scientific circles, the... more...

CHAPTER I. STRUCTURE OF THE BACTERIA AND CONDITIONS GOVERNING THEIR DEVELOPMENT AND DISTRIBUTION. Before one can gain any intelligent conception of the manner in which bacteria affect dairying, it is first necessary to know something of the life history of these organisms in general, how they live, move and react toward their environment. Nature of Bacteria. Toadstools, smuts, rusts and mildews are known to even the casual observer, because... 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 dial-plate of "that clock whose pendulum... more...

CHAPTER I. ON THE RECIPROCAL INFLUENCE OF SCIENCE AND EDUCATION. That the state of knowledge in any country will exert a directive influence on the general system of instruction adopted in it, is a principle too obvious to require investigation. And it is equally certain that the tastes and pursuits of our manhood will bear on them the traces of the earlier impressions of our education. It is therefore not unreasonable to suppose that some... more...

About the middle of the Miocene period, as well as I can now remember (for I made no note of the precise date at the moment), my islands first appeared above the stormy sheet of the North-West Atlantic as a little rising group of mountain tops, capping a broad boss of submarine volcanoes. My attention was originally called to the new archipelago by a brother investigator of my own aerial race, who pointed out to me on the wing that at a spot some... more...

How does it come about that alongside of the idea of ponderable matter, which is derived by abstraction from everyday life, the physicists set the idea of the existence of another kind of matter, the ether? The explanation is probably to be sought in those phenomena which have given rise to the theory of action at a distance, and in the properties of light which have led to the undulatory theory. Let us devote a little while to the consideration... more...
