ADVANCE OF ASTRONOMY DURING THE NINETEENTH CENTURY.
SIE BOBEBT BALL
ONE of the most remarkable chapters in the astronomy of the past century was commenced on the very first night with which that century began. It was, indeed, on the 1st of January, 1801, that the discovery of a new planet was announced. Th great orbs—Jupiter, Saturn, Mercury, Mars, and Venus—had known from the earliest times of which we have records, ar planet Uranus had been discovered nearly twenty years before previous century closed.
THERE is something about fire which fascinates every one, yet the action of explosives arouses even a livelier interest, since the accompanying fiery phenomena are more intense and are attended with a shocking report and a violent destruction of the surrounding material, while this train of events, with all its marked
WHILE I have had the privilege of making several indirect studies of anarchists by means of the data furnished by legal processes, the journals, and the handwriting of the subjects, I have only rarely been able to examine one directly and make those measurements and craniological determinations upon him without which any study can be only approximate, or, we might even say, hypothetical.
OF all the wonderful operations accomplished by the aid of electricity at the present time, none so completely mystifies the beholder as the action of the trolley car. The electric light, although incomprehensible to the average layman, does not excite his curiosity to the same extent.
IT is during the latter part of the present century that a general movement has arisen to give women their rights in business life and in political and social affairs. It is the intention of this article to treat of this movement, especially in its relation to education, in Germany, where, of all civilized lands, it has had apparently the smallest results.
ALTHOUGH amateurs have played a conspicuous part in telescopic discovery among the heavenly bodies, yet every owner of a small telescope should not expect to attach his name to a star. But he certainly can do something perhaps more useful to himself and his friends.
IN a recent advertisement, Professor Ward’s work entitled as above was characterized as “ one of the most important contributions to philosophy made in our time in England,” and this was joined with the prophecy that it “ may even do something to restore to philosophy the prominent place it once occupied in English thought.”
EVERTING to the dictionary for a definition, electrolysis is "the process of decomposing a chemical compound by the passage of an electric current through it.” Electroplating is a popular illustration of this definition, having been numbered among the industrial arts for nearly a century.
MOST of us are so used to thinking of birds, if we notice them at all, as belonging to spring and summer that we easily fail to see or hear the comparatively few feathered winter visitors. Among these, however, are some of the most attractive and amusing of birds, and to hear their cheery notes and to watch their busy hunt for food on a cold winter day adds a very considerable pleasure to a walk in a city park or the near-by woods.
OLD RATTLER was a snake, of course, and he lived in the King’s River Cañon, high up and down deep in the mountains of California. He had a hole behind and below a large, flat granite rock, not far from the river, and he called it his home; for in it he slept all night and all winter, but when the sun came back in the spring and took the frost out of the air and the rocks, then he crawled out to lie until he got warm.
EVERY one knows that the Philippine archipelago, like other regions in its neighborhood, abounds in volcanoes, some of which are still active, while the majority are extinct. Some geologists have tried to distribute the Philippine volcanoes into two parallel belts or lines running in a general northwest and southeast direction, following the trend of the island group, and extending from the southern end of Mindanao to the northern part of Luzon—some sixteen degrees of latitude.
THE labors of M. Metchnikoff have made known one of the most curious mechanisms—perhaps the most effective—which Nature employs to protect the organism against the invasion and ravages of microbes. We are only beginning to learn the means which are provided for our defense against the countless swarms of enemies of this class, some of them exceedingly dangerous, among which we have to live and move.
IN a most thoughtful article, in the Modern Education Series of The Cosmopolitan, President Hadley, of Yale, remarks that the conception of a liberal education changes as forms of government change. “It takes one shape,” he proceeds to say, “ in a military state, and quite another shape in a state ruled by public opinion.
Zola’s Anthropological Traits.— Mr. Arthur MacDonald has published, originally in the Open Court, a minute anthropological study of the personality of Êmile Zola. Passing all the physical points noted, we select a few only of the most peculiar mental traits mentioned by the author.
