Page xxiii - Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science In different parts of America, to give a stronger and more general impulse and more systematic direction to scientific research, and to procure for the labors of scientific men increased facilities and a wider usefulness.
Page 309 - Under whatever aspect we view this cranium, whether we regard its vertical depression, the enormous thickness of its supraciliary ridges, its sloping occiput, or its long and straight squamosal suture, we meet with ape-like characters, stamping it as the most pithecoid of human crania yet discovered.
Page 2 - And there was seen another sign in heaven ; and behold, a great red dragon, having seven heads and ten horns, and upon his heads seven diadems.
Page 296 - ... new linguistic stock, all that is needed is that two or more young children should be placed by themselves in a condition where they will be entirely, or in a large degree, free from the presence and influence of their elders. They must, of course, continue in this condition long enough to grow up, to form a household, and to have descendants to whom they can communicate their new speech.
Page 322 - Perthes had startled the civilized world, — that is, somewhere between six thousand and ten thousand years ago. And this man who thus appeared was not a being of feeble powers, a dullwitted savage, on the mental level of the degenerate Australian or Hottentot of our day. He possessed and manifested, from the first, intellectual faculties of the highest order, such as none of his descendants have surpassed. His speech, we may be sure, was not a mere mumble of disjointed sounds, framed of interjections...
Page 51 - Auadehnungslehre, with which he had but recently become acquainted, expresses ''his profound admiration of that extraordinary work, and his conviction that its principles will exercise a vast influence upon the future of mathematical science." Another subject in which we find a tendency toward the forms and methods of multiple algebra, is the calculus of operations. Our ordinary analysis introduces operators ; and the successive operations A and B may be equivalent to the operation C.
Page 9 - If those complicated lines have any meteoroid origin (which seems very unlikely) they suggest rather the phenomena of comets' tails than meteoroid streams or sporadic meteors. The hypothesis that the long rays of light which sometimes have been seen to extend several degrees from the sun at the time of the solar eclipse are meteor streams seen edgewise seems possibly true, but not at all probable. The observed life of the meteor is only a second, or at most a few seconds, except when a large one...
Page 318 - But a race of dumb men, deprived of all communication with those who could speak, would be little indeed removed from the brutes. And the moral and intellectual difference between them and ourselves would be practically infinite, though the naturalist should not be able to find a single shadow of even specific structural difference.
Page 11 - Meimier and others into the structure of meteorites have brought out many facts which make their hypothesis plausible. It requires, however, that the stone-meteor be not regarded as of the same nature as the star-shower meteor, for no one now seriously claims that the comets are fragments of a broken planet. The hypothesis of the existence of such a planet is itself arbitrary ; and it is not easy to understand how any mass that has become collected by the action of gravity and of other known forces...
Page 9 - There exist no doubt multitudes of these minute particles traveling in space. But science asks not only for a true cause but a sufficient cause. There must be enough of this matter to do the work assigned to it. At present, we have no evidence that the total existing quantity of such fine material is very large. It is to be hoped that through the collection and examination of meteoric dust we may soon learn something about the amount which our earth receives. Until that shall be learned we can reason...
