Сторінка 326 - I felt the sentiment of Being spread O'er all that moves and all that seemeth still, O'er all that, lost beyond the reach of thought And human knowledge, to the human eye Invisible, yet liveth to the heart ; O'er all that leaps and runs, and shouts and sings, Or beats the gladsome air ; o'er all that glides Beneath the wave, yea, in the wave itself, And mighty depth of waters.
Сторінка 312 - Beagle," as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America, and in the geological relations of the present to the past inhabitants of that continent.

Сторінка 100 - Without further remark we shall give Newton's Three Laws ; it being remembered that as the properties of matter might have been such as to render a totally different set of laws axiomatic, these laws must be considered as resting on convictions drawn from observation and experiment and not on intuitive perception?
