352. oldal - ... and how in another instant, by a change in that volition, all these muscles are thrown into a different state, and a new set brought into action, and so on continually as long as he pleases, his mind is lost in the immensity of wonder that this excites. But when he farther reflects, that it is not only he himself that is endowed with the faculty of calling forth these incomprehensible energies, but that the most insignificant insect is vested with powers of a similar sort, he is still more confounded....
79. oldal - Still there are who raptured view Scenes which youthful hopes endear Where they science learn to woo ; Still they love to wander here. Peace they meet in every grove ; Lives again the rapturous song 5 Sweetly sportive still they rove, Cam ! thy sedgey banks along.

469. oldal - I little imagined, when I took my last leave of the walks of public life, that any event could bring me again on a public theatre. But the unjust conduct of France towards these United States has been and continues to be such, that it must be opposed by a firm and manly resistance, or we shall not only hazard the subjugation of our government, but the independence of our nation also ; both being evidently struck at by a lawless, domineering power...
109. oldal - I have studied it ever since June last, and have found in it striking characteristics of both plant and animal. It is a little aquatic being; at first sight, every one imagines it to be a plant ; but, if it be a plant, it is sensitive and ambulent : if it be an animal, it may be propagated by slips, or cuttings, like many plants.

A skilful naturalist has been able to perceive, that in the body of the poorest caterpillar, which, in the common opinion is one of the most degraded existences on this globe, there are upwards of two thousand muscles, all of which can be brought into action with as much facility at the will of that insect, and perform their several offices with as much accuracy, promptitude, and precision, as in the most perfect animal ; and all this is done by that insect...
122. oldal - Yet, according to the account of Don Ulloa, these three discordant climates seldom encroach much on each other's territories. The hot winds below, if they ascend, become cooled by their expansion ; and hence they cannot affect the snow upon the summit ; and the cold winds, that sweep the summit, become condensed as they descend, and of temperate warmth before they reach the fertile plains of Quito.
470. oldal - The gardener, whom you were so obliging as to send me, continues to conduct himself extremely well. He is industrious, sober, and orderly, and understands his business. In short, I never had a hired servant that pleased me better; and what adds to my satisfaction is, that he is himself contented, having declared that he never was happier in his life.
121. oldal - Now, as the vast region of air which surrounds our globe is perpetually moving along its surface, climbing up the sides of mountains, and descending into the valleys, as it passes along, it must be perpetually varying the degree of heat according to the elevation of the country it traverses; for in rising to the summits of mountains it becomes expanded, having so much of the pressure of the superincumbent atmosphere taken away ; and when thus expanded, it attracts or absorbs heat from the mountains...
