第 125 頁 - O ! who can hold a fire in his hand By thinking on the frosty Caucasus? Or cloy the hungry edge of appetite By bare imagination of a feast?
第 148 頁 - Atlantic surge Pours in among the stormy Hebrides ; Who can recount what transmigrations there Are annual made ? what nations come and go ? And how the living clouds on clouds arise ? Infinite wings ! till all the plume-dark air, And rude resounding shore are one wild cry.
第 173 頁 - ... to the ground, as though there had been no wind at all, straightway it would rise and fly again. And that which was the most marvel of all, at one time two drifts of snow flew, the one out of the west into the east, the other out of the north into the east: and I saw two winds by reason of the snow, the one cross over the other, as it had been two highways.
第 107 頁 - O'erhang and jutty his confounded base, Swill'd with the wild and wasteful ocean. Now set the teeth and stretch the nostril wide, Hold hard the breath and bend up every spirit To his full height.

第 32 頁 - ... strike at the same instant against the pegs opposite to them, the ball of clay would not be moved from its place to either side ; nevertheless the peg impelled by the smaller body B, which has the double velocity, would be found to have penetrated twice as far as the peg impelled by A.
第 218 頁 - Our wrestling at arms is turned to wallowing in ladies' laps; our courage to cowardice; our running to riot; our bows into bowls; and our darts to dishes. We have robbed Greece of gluttony, Italy of wantonness, Spain of pride, France of deceit, and Dutchland of quaffing. Compare London to Rome, and England to Italy, you shall find the theatres of the one, the abuses of the other, to be rife among us.
第 65 頁 - Duhamel, and that I had one fact to communicate relative to the effects produced by the stagnation of the descending sap of resinous trees, which appeared to lead to important consequences. I have in my possession a piece of a fir-tree, from which a portion of bark, extending round its whole stem, had been taken off several years before the tree was felled ; and of this portion of wood, one grew above, and the other below, the decorticated space.
第 77 頁 - ... that his life had become a burden to him ; but he succeeded in reducing himself to a moderate bulk by the following means : His reformed diet consisted of a simple pudding made by boiling coarse flour in water, without salt. Of this he consumed about three pounds in twenty-four hours, and took no fluid whatever, not even water.
