Страница 231 - It is true, that a little philosophy inclineth man's mind to atheism ; but depth in philosophy bringeth men's minds about to religion : for while the mind of man looketh upon second causes scattered, it may sometimes rest in them, and go no farther ; but when it beholdeth the chain of them confederate and linked together, it must needs fly to Providence and Deity.
Страница 9 - Soon shall thy arm, unconquered steam, afar Drag the slow barge or drive the rapid car ; Or, on wide-waving wings expanded, bear The flying chariot through the fields of air...
Страница 50 - ... comes the potent agency of steam. In comparison with the past, what centuries of improvement has this single agent comprised, in the short compass of fifty years ! Everywhere practicable, everywhere efficient, it has an arm a thousand times stronger than that of Hercules, and to which human ingenuity is capable of fitting a thousand times as many hands as belonged to Briareus. Steam is found in triumphant operation on the seas ; and under the influence of its strong propulsion, the gallant ship,...
Страница 304 - Led by this indication he tries the effect of iodine on that complaint, and the result establishes the extraordinary fact that this singular substance, taken as. a medicine, acts with the utmost promptitude and energy on goitre, dissipating the largest and most inveterate in a short time, and acting (of course, like all medicines, even ihe most approved, with occasional failures,) as a specific, or natural antagonist, against that odious deformity.
Страница 301 - ... direction of the intended separation, along which a groove is cut with a chisel about a couple of inches in depth. Above this groove a narrow line of fire is then kindled, and maintained till the rock below is thoroughly heated, immediately on which a line of men and women, each provided with a pot full of cold water, suddenly sweep off the ashes, and pour the water into the heated groove, when the rock at once splits with a clean fracture. Square blocks of six feet in the side, and upwards of...
Страница 203 - This, however, does by no means hinder us from applying the rest of our time, beside what nature requires for meals and rest, to the study of science ; and he who, in whatever station his lot may be cast, works his day's work, and improves his mind in the evening, as well as he who, placed above such necessity, prefers the refined and elevating pleasures of knowledge to the low gratification of the senses, richly deserves the name of a True Philosopher.
Страница 11 - I elevated myself upon a platform, and addressed the assembly. I stated, that I knew not what was the matter ; but if they would be quiet, and indulge me for a half hour, I would either go on, or abandon the voyage for that time.
Страница 271 - Nothing, then, can be more unfounded than the objection which has been taken in limine, by persons, well meaning perhaps, certainly narrow-minded, against the study of natural philosophy, and, indeed, against all science, — that it fosters in its cultivators an undue and overweening self-conceit, leads them to doubt the immortality of the soul, and to scoff at revealed religion.

Страница 204 - The highest of all our gratifications in the contemplations of science remains : we are raised by them to an understanding of the infinite wisdom and goodness which the Creator has displayed in all his works.
