Halaman 631 - Whereas it is necessary for the support of government, for the discharge of the debts of the United States, and the encouragement and protection of manufactures, that duties be laid on goods, wares, and merchandises imported: Be it enacted, etc.
Halaman 20 - ... there is no reason to deny the final cessation of the sun's activity, and the consequent death of the system. But while this hypothesis seems fairly to meet the requirements of the case, and to be a necessary consequence of the best knowledge we can obtain as to the genesis of our system and the constitution of the sun itself, it must, of course, be conceded that it does not yet admit of any observational verification. N"o measurements within our power can test it, so far as appears at present.
Halaman xxiii - The objects of the 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.
Halaman 693 - The undersigned respectfully request the British Association for the Advancement of Science and the American Association for the Advancement of Science...
Halaman 16 - Herschel (still quoted as authoritative in numerous school-books), that the central core of the sun is a solid and even habitable globe, having the outer surface of its atmosphere covered with a sheet of flame maintained by some action of the matter diffused in the space through which the system is rushing. We must admit that the question of the sun's constitution is not yet beyond debate. And not only the constitution of the sun itself, but the nature and condition of the matter composing it, is...
Halaman 469 - Clepsydrops natalis, where it is preserved in position, shows that this horizontal ramus of the quadrate is nothing more than the zygomatic process of the squamosal bone of the Mammalia, forming with the malar bone the zygomatic arch.
Halaman 692 - ... exhibitors, and to the efficient committeemen and aids who have made it the admirable success it has proved itself to be. Secondly : with the same or a still greater sense of obligation, we may say still more, if possible, of the exhibition of microscopes and microscopic objects which will be offered to us by the Biological and Microscopical Section of the Academy of Natural Sciences, in the foyer or upper hall, to-night.
Halaman 4 - ... way of the moon, to bridge the ocean, and ascertain how other stations are related to those which were taken as primary. I do not, of course, mean to imply, that, in the present state of observational astronomy, any such procedure would lead to results of much value ; but, before the Asiatic triangulation meets the American at Behring's Strait, it is not unlikely that the accuracy of lunar observations will be greatly increased.
Halaman 582 - ... rivals. The ancestors of the ungulates held the fields and the swamps, and the Carnivora, driven by hunger, learned the arts and cruelties of the chase. The weaker ancestors of the Quadrumana possessed neither speed nor weapons of...
Halaman 455 - It will be found excellent practice in the mental operations required by this doctrine to imagine a train, the fore part of which is an engine and three carriages linked with iron couplings, and the hind part three other carriages linked with iron couplings ; the bond between the two parts being made up out of the sentiments of amity subsisting between the stoker and the guard.
