Страница 266 - Dictionary was written with little assistance of the learned, and without any patronage of the great ; not in the soft obscurities of retirement, or under the shelter of academick bowers, but amidst inconvenience and distraction, in sickness and in sorrow.
Страница vi - Phoebus replied, and touched my trembling ears: "Fame is no plant that grows on mortal soil, Nor in the glistering foil Set off to the world, nor in broad rumour lies, But lives and spreads aloft by those pure eyes And perfect witness of all-judging Jove; As he pronounces lastly on each deed, Of so much fame in heaven expect thy meed.
Страница 91 - An admirable and most forcible way to drive up water by fire, not by drawing or sucking it upwards, for that must be as the philosopher calleth it, infra spheeram activitatis, which is but at such a distance. But this way hath no bounder, if the vessels be strong enough ; for I have taken a piece of a whole cannon, whereof the end was burst, and filled it...
Страница v - That life is not as idle ore, But iron dug from central gloom, And heated hot with burning fears, And dipt in baths of hissing tears, And batter'd with the shocks of doom To shape and use.
Страница 329 - Nor was this all the honour done to his reverend ashes; for as there be some persons that will not receive a reward for that for which God accounts Himself a debtor; persons that dare trust God with their charity, and without a witness; so there was, by some grateful unknown friend, that thought Dr.
Страница 393 - Swedish artist having been instructed by him that rats' whiskers make the most pliant and elastic painting-brush ; ladies would appeal to him on the best means of devising grates, curing smoking chimneys, warming their houses, and obtaining fast colours. I can speak from experience of his teaching me how to make a dulcimer and improve a Jew's harp.
Страница 64 - The means of accomplishing these points did not immediately present themselves ; but early in 1765 it occurred to me, that if a communication were opened between a cylinder containing steam, and another vessel which was exhausted of air and other fluids, the steam, as an elastic fluid, would immediately rush into the empty vessel, and continue to do so until it had established an equilibrium ; and if that vessel were kept very cool by an injection or otherwise, more steam would continue to enter...
Страница 402 - By his admirable contrivance, it has become a thing stupendous alike for its force and its flexibility, for the prodigious power which it can exert, and the ease, and precision, and ductility, with which it can be varied, distributed, and applied. The trunk of an elephant, that can pick up a pin or rend an oak, is as nothing to it. It can engrave a seal, and crush masses of obdurate metal before it ; draw out, without breaking, a thread as fine as gossamer, and lift a ship of war like a bauble in...

Страница 402 - It can engrave a seal, and crush masses of obdurate metal like wax, before it, — draw out, without breaking, a thread as fine as gossamer, and lift a ship of war like a bauble in the air. It can embroider muslin, and forge anchors, — cut steel into ribands, and impel loaded vessels against the fury of the winds and waves.
