THE few hints afforded by geology respecting the earliest stages of the earth’s history, when compared with studies into the nature of nebulæ, comets, and suns, suggest the existence of a series of mutations through which worlds destined for the occupation of intelligent beings must pass, in order to be properly fitted for the residence of mind.
THROUGHOUT the realms of Nature motion is indispensable to physical stability and organic existence. It is everywhere present, and equally among molecules and masses the mind searches in vain for evidence of absolute rest. It has been declared that “organic life is a result of motion;” certain it is that motion is a condition of life.
WITH the concluding paragraph of the previous article replying to criticisms I had hoped to end, for a long time, all controversial writing. But, while it was in the printer’s hands, two criticisms, more elaborate than those dealt with above, made their appearance; and, now that the postponed publication of this latter half of the article affords the opportunity, I cannot, without risking misinterpretations, leave these criticisms unnoticed.
IF there is to-day a fact demonstrated by reason reflexly contemplating itself no less than by attentive observation of the entire development of human knowledge, it is the close interdependence of all natural forces and operations—a solidarity so firmly knit that it is impossible to study any one point of detail without reference to the sum total of the phenomena.
LET us consider the views entertained by our ancestors for centuries on the goose question:we may gather lessons from it that will be very applicable to-day. They believed for five hundred years that a certain kind of goose was of vegetable origin, and grew on trees.
THE diminution of the efficacy of vaccination, as a preservative from the small-pox, has been the subject, at first of incredulity, and afterward of surprise, to the medical world, and even to the non-professional public. The causes of this change have been sought in the nature of the vaccine matter.
LET US now pass to the examination of a theory which was proposed in 1807 by the now justly-celebrated Thomas Young who seems to have been gifted with a scientific insight much too keen for the age in which he lived. His views being opposed to the common notions of the day, commanded but little attention, and it was reserved for Helmholtz, almost half a century later, to call attention to this nearly-forgotten theory, and to show that it accounted for all the ascertained facts in a most satisfactory manner.
I TAKE it for granted that most Americans who have traveled in England know of, if they don’t actually know, Clapham Junction. It is a marvelous place is that Clapham Junction—a half-dozen or more naked-looking graveled platforms, destitute of almost every convenience in the shape of waiting and refreshment rooms, forming altogether one of the most important, not to say intricate, railway-depots in the United Kingdom.
THE methods of estimating the facial angle hitherto adopted by naturalists are all mere modifications of that proposed by Peter Camper, and consist in describing an angle with one line passing along the base of the skull, intersected by another which passes from the anterior portion of the upper jaw over the forehead.
AFTER Death! The last faint breath had been noted, and another watched for so long, but in vain. The body lies there, pale and motionless, except only that the jaw sinks slowly but perceptibly. The pallor visibly increases, becomes more leaden in hue, and the profound, tranquil sleep of Death reigns where just now were life and movement.
THERE are few ideas more fatal to the exercise of that prophetic sight, by which we hope to penetrate the uncertainty of the what-is-to be, and distinguish the dark forms of the future, than the two notions:that history repeats itself, and that any form of feeling, of thought, or of motive, when once extinguished, must forever remain so.
LOUIS JEAN RODOLPHE AGASSIZ, whose death occurred the 14th of last December, was born May 28, 1807, in Mottier, Switzerland. From his earliest childhood he evinced a remarkable fondness for the study of natural science, and before he had left school began to collect and study into the habits of fishes.
“However earnestly we may contend for such a notion of Philosophy as shall keep up the tradition of it as something more than Science, yet the perpetual liability of Philosophy to modifications, at the hands of Science, is a fact obvious to all.
WE speak, in another place, of the importance of the great principle of the conservation of energy as a fundamental truth of modern science. The literature of this subject has hitherto been copious, but, as it has been mainly the product of minds engaged with the original research, it has often been so technical and complicated as to be difficult to popular apprehension.
England and America.—Prof. Tyndall writes as follows to the editor of the London Daily Telegraph:Sir—You have given me a challenge, to which I willingly respond. In a speech, to which I had the honor of listening just before my departure from America, Hon. William M. Evarts used these words: “There is a generous and perfect sympathy between the educated men of England and the educated men of the United States.
THE latest application of the sand-blast is for cleaning the fronts of buildings, by removing the soot, dust, and other substances therefrom. The impact of the sand on the surface removes the dirt from all the crevices and indentations, without perceptibly affecting the sharpness of the architectural ornamentation.
