Page 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.
Page 92 - Q) and vanish when n — £1 — that is to say, at the beginning and end of the evolution by friction of the earth-moon system. It is quite clear, therefore, that the remarkable expression (1) found by Mr. Darwin is not peculiar to his special hypothesis of a viscous earth, but can be deduced equally well from the totally distinct hypothesis of an absolutely rigid earth retarded by the tidal action of a liquid ocean. I was led by this result to consider the case of the earthmoon, separating (as...
Page 87 - Conference, the United States Transit of Venus Commission took a very different view of the case. Its members knew that the probable error of a contact observation is 0.15 of a second of arc, that there may always be a doubt as to the phase observed, and that a passing cloud may cause the loss of the transit. They also knew that the photographic method cannot be defeated by passing clouds, is not liable to any uncertainty of interpretation, seems to be free from systematic errors, and is so accurate...
Page 3 - ... valleys and plains that were the scenes of our youthful excursions. In vain did we doubt that the glittering spangles of mica and the still more alluring brilliancy of pyrites gave assurance of the existence of the precious metals in those substances, or that the cutting of glass by the garnet and by quartz proved that these minerals were the diamond ; but, if they were not precious metals, and if they were not diamonds, we in vain inquired of our companions, and even of our teachers, what they...
Page 70 - LeConte declared to be unexplained ; while such is the case ' the actual mountain formation," to use his words, is still unaccounted for. That these gentle and widespread movements of oscillation are, however, in some way not yet clearly explained, connected with the contracting of the nucleus, and the consequent conforming thereto of the envelope, we can scarcely doubt ; or that the latter, from its nature and origin, must present great differences in constitution and in flexibility in its various...

Page 2 - the investigation of the mineral and fossil bodies which compose the fabric of the globe, and more especially for the natural and chemical history of the minerals and fossils of the United States.
Page 218 - ... another cell, the dead resistance of which is also added to the circuit. In consequence, it is not safe in practice to draw from a secondary battery all the energy it should be capable of yielding, and in most cases not more than half can be safely taken out of it. In place of continuing uniform as in a single cell, the electromotive force of a series of cells begins to fall when about half the charge which it ought to be capable of yielding has been drawn from it.
Page 77 - We are now on the eve of the second transit of a pair, after which there will be no other till the twenty-first century of our era has dawned upon the earth, and the June flowers are blooming in 2004. When the last transit season occurred the intellectual world was awakening from the slumber of ages, and that wondrous scientific activity which has led to our present advanced knowledge was just beginning. What will be the state of science when the next transit season .arrives God only knows.
Page 241 - The fyfth of Putrefaction then followe shall ; Of Congelation Albyficative shall be the sixt, Then of Cybation, the seaventh shall follow next. The secret of our Sublymation the eyght shall show; The nynth shall be of Fermentatyon ; The tenth of our Exaltation I trow. The elevent of our mervelose Mnltiplycatyon, The twelfth of Projection ; then Eecapitulatyon, And so this treatise shall take an end, By the help of God, as I entend.
