Pàgina 240 - And the house, when it was in building, was built of stone made ready before it was brought thither : so that there was neither hammer nor axe nor any tool of iron heard in the house, while it was in building.
Pàgina 180 - It is indisputably evident that a great part of every man's life must be employed in collecting materials for the exercise of genius. Invention, strictly speaking, is little more than a new combination of those images which have been previously gathered and deposited in the memory: nothing can come of nothing: he who has laid up no materials can produce no combinations.
Pàgina 180 - But Knowledge to their eyes her ample page, Rich with the spoils of time, did ne'er unroll ; Chill Penury repressed their noble rage And froze the genial current of the soul.
Pàgina 165 - Passing to the consideration of electro-chemical decomposition, it appears to me that the effect is produced by an internal corpuscular action, exerted according to the direction of the electric current, and that it is due to a force either superadded to, or giving direction to the ordinary chemical affinity of the bodies present.
Pàgina 75 - ... with a majestic slowness ; at intervals we thought they were coming in a very few minutes to overwhelm us ; and small quantities of sand did actually more than once reach us. Again they would retreat so as to be almost out of sight, their tops reaching to the very clouds.
Pàgina 165 - For though all the particles in the line of induction resist charge, and are associated in their actions so as to give a sum of resisting force, yet when any one is brought up to the overturning point, all must give way in the case of a spark between ball and ball.
Pàgina 165 - I believe at present that it can. But when what I consider the true effect only was obtained, the quantity of gas given off was so small that I could not ascertain whether it was, as it ought to be, oxygen at one wire and hydrogen at the other. Of the two streams one seemed more copious than the other, and on turning the apparatus round, still the same side in relation to the machine gave the largest stream. On substituting solution of sulphate of soda for pure water...
Pàgina 245 - The most remarkable," says Sir Gardiner Wilkinson, " are the door-ways surrounding the tanks of Assassief, which are composed of two or more concentric semicircles of brick, as well constructed as at the present day, and all the bricks radiate to a common centre.
Pàgina 165 - The production of a polarized state of the particles of neighboring matters by an excited body, constitutes induction, and this arises from its action upon the particles in immediate contact with it, which again act upon those contiguous to them, and thus the forces are transferred to a distance. If the induction remain undiminished, then perfect insulation is the consequence ; and the higher the polarized condition...
Pàgina 124 - I do hereby declare, that my constituents have no local interest, and that I have no personal interest, in such bill ; and that I will never vote on any question which may arise without having duly heard and attended to the evidence relating thereto.
