STORY OF A SALMON.

PROFESSOR DAVID S. JORDAN
IN the realm of the Northwest Wind, on the boundary-line between the dark fir-forests and the sunny plains, there stands a mountain, a great white cone two miles and a half in perpendicular height. On its lower mile, the dense fir-woods cover it with never-changing green; on its next half-mile, a lighter green of grass and bushes gives place in winter to white; and, on its uppermost mile, the snows of the great Ice age still linger in unspotted purity.

PHYSICAL EDUCATION.

FELIX L. OSWALD
PHYSICAL vigor is the basis of all moral and bodily welfare, and a chief condition of permanent health. Like manly strength and female purity, gymnastics and temperance should go hand in hand. An effeminate man is half sick ; without the stimulus of physical exercise, the complex organism of the human body is liable to disorders which abstinence and chastity can only partly counteract.

THE MINERAL SPRINGS OF SARATOGA.*

CHARLES F. FISH
ASIDE from the rich field for scientific research that the mineral springs of Saratoga present to the student of natural phenomena, the majority of the members of this Association are undoubtedly interested to a greater or less extent in a product that forms, with many, a large, important, and increasing item of trade, there being probably no one class of mineral waters of domestic production, or from any one locality, that are used to so great an extent as those from Saratoga Springs.

ACTION OF RADIANT HEAT ON GASEOUS MATTER.

PROFESSOR JOHN TYNDALL
THE Royal Society has already done me the honor of publishing a long series of memoirs on the interaction of radiant heat and gaseous matter. These memoirs did not escape criticism. Distinguished men, among whom the late Professor Magnus and the late Professor Buff may be more specially mentioned, examined my experiments, and arrived at results different from mine.

ANOTHER WORLD DOWN HERE.

W. MATTIEU WILLIAMS
WHAT a horrible place must this world appear when regarded according to our ideas from an insect’s point of view ! The air infested with huge flying hungry dragons, whose gaping and snapping mouths are ever intent upon swallowing the innocent creatures for whom, according to the insect, if he were like us, a properly constructed world ought to be exclusively adapted.

H. J. JOHNSTON-LAVIS
IT is observable in certain volcanoes that the lava frequently strewed around after an eruption contains more or less perfect spheres, consisting of a hard external coat and more scoriaceous contents, and these from their resemblance are known as volcanic bombs.

PROFESSOR HERMANN COHN
IT was formerly considered, and some recent text-books have repeated the error, that the qualities of near-sighted and long-sighted eyes were opposed. The investigations of Professor Donders, of Utrecht, have, however, shown that not only is long-sightedness not the opposite of near-sightedness, but that the two defects may be associated in the same individual.

DEEP-SEA INVESTIGATION.*

J. G. BUCHANAN
THE first problem of deep-sea investigation is to determine the extent of the ocean, its size, its volume. The superficial extent and limits are determined by the surveyor. In order to map out the bottom of the sea, there is only one method, namely, the direct determination of the depth at as many places as possible.

T. F. THISELTON DYER
AMONG the many sources of superstition in this and other countries, the phenomenon well known as the Will-o’-the-Wisp has from time immemorial held a prominent place. Indeed, it would be no easy task to enumerate the various shapes in which the imagination has pictured this mysterious appearance, not to mention the manifold legends that have clustered round it.

CYNICISM OPPOSED TO PROGRESS.

WILLIAM A. EDDY
WHEN examining a question of possible corruption, or any form of crime, we find that nearly all men take a somewhat cynical view. So common is this that we may safely say that it applies to all who know the world. Yet a careful examination of facts, though giving us a vague idea of the real proportion of crime, must finally convince us that cynicism is simply the sentinel on guard to warn us against possible injury from exceptional qualities in others.

THERE is a schoolhouse in a convenient little by-street in Boston, which is visited weekly by scholars and scientists, specialists of renown and commonplace fathers and mothers, philanthropists and seekers after the curious, and from its doors not one turns away without being surprised and touched.

S. R. KOEHLER
WE have become so accustomed to color in all the objects about us, that we may almost be said to take no notice of it. Day after day we look upon the wealth of color in the landscape by which we are surrounded, without hardly ever giving it a thought.

H. N. DRAPER
SO much has already been written by way of contribution to our knowledge of the different species of the eucalyptus-tree, that, interesting as the subject is, it may well be considered to have received already a fair share of attention. There is one aspect of it, however, which can not perhaps be dwelt upon too much, and that is the value of this genus of plants as drainers of the soil and purifiers of the atmosphere.

IT is a beautiful theory that man was made for society ; but it is an eminently better one that society was made for man. Man was necessarily in existence before society. He contains within himself all the virtues that are an ornament to society, all the elements that strengthen government.

THOUGH still a young man, having just entered on his prime, Professor Cope is widely known for his enthusiasm and industry in scientific pursuits. Already he has accomplished an amount of original work in his chosen field of investigation that would do credit to an ordinary lifetime, and that justly entitles him to the place he now holds among the foremost of American biologists.

THE elegant research of Professor Tyndall, which we publish in the present number,will well repay the careful attention of our readers. It is of interest, not only on account of the very complete confirmation of results previously obtained by this physicist, but also on account of the novel method employed, and the promise this gives of wide utility.

A THERMOMETRIC bureau has been established, in connection with the Winchester Observatory of Yale College, for the more accurate graduation and verification of thermometers. The thermometers in common use are, as a rule, not graduated with any approach to scientific accuracy, and the best of them, however exact they may be when new, increase their readings rapidly within a few months, so as to become as much as 2° in error in the course of a year.
