Page 503 - Those who have handled sciences have been either men of experiment or men of dogmas. The men of experiment are like the ant; they only collect and use: the reasoners resemble spiders, who make cobwebs out of their own substance. But the bee takes a middle course ; it gathers its material from the flowers of the garden and of the field, but transforms and digests it by a power of its own.
Page 493 - To give a stronger impulse and a more systematic direction to scientific inquiry, — to promote the intercourse of those who cultivate Science in different parts of the British Empire, with one another and with foreign philosophers, — to obtain ft more general attention to the objects of Science, and a removal of any disadvantages of a public kind which impede its progress.
Page xxi - 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 509 - Wherefore shall we die before thine eyes, both we and our land? buy us and our land for bread, and we and our land will be servants unto Phar-aoh: and give us seed, that we may live, and not die, that the land be not desolate.
Page 503 - For though it be true that I am principally in pursuit of works and the active department of the sciences, yet I wait for harvest-time, and do not attempt to mow the moss or to reap the green corn. For I well know that axioms once rightly discovered will carry whole troops of works along with them, and produce them, not here and there one, but in clusters. And that unseasonable and puerile hurry to snatch by way of earnest at the first works which come within reach, I utterly condemn and reject,...
Page 329 - Consequently, if the theory be true, it is indisputable that before the lowest Cambrian stratum was deposited long periods elapsed, as long as, or probably far longer than, the whole interval from the Cambrian age to the present day ; and that during these vast periods the world swarmed with living creatures.

Page 81 - And if at any time I speak of Light and Rays as coloured or endued with Colours, I would be understood to speak not philosophically and properly, but grossly, and accordingly to such Conceptions as vulgar People in seeing all these experiments would be apt to frame. For the Rays to speak properly are not coloured. In them there is nothing else than a certain Power and Disposition to stir up a Sensation of this or that Colour.
Page 502 - For first, the object of the natural history which I propose is not so much to delight with variety of matter or to help with present use of experiments, as to give light to the discovery of causes and supply a suckling philosophy with its first food. For though it be true that I am principally in pursuit of works and the active department of the sciences, yet I wait for harvest-time, and do not attempt to mow the moss or to reap the green corn.
Page 82 - tis a Sense of that Motion under the Form of Sound ; so Colours in the Object are nothing but a Disposition to reflect this or that sort of Rays more copiously than the Rest; in the Rays they are nothing but their Dispositions to propagate this or that Motion into the Sensorium, and in the Sensorium they are Sensations of those Motions under the Forms of Colours.
