399 psl. - Engineer, being the art of directing the great sources of power in nature for the use and convenience of man...
57 psl. - It is a strange thing that in sea voyages, where there is nothing to be seen but sky and sea, men should make diaries ; but in land-travel, wherein so much is to be observed, for the most part they omit it, as if chance were fitter to be registered than observation.
447 psl. - For anglers, in spring, it is always unlucky to see single magpies, but two may be always regarded as a favourable omen ; and the reason is, that in cold and stormy weather one magpie alone leaves the nest in search of food, the other remaining sitting upon the eggs or the young ones ; but when two go out together, it is only when the weather is warm and mild, and favourable for fishing.
432 psl. - The manufacturer assured him that he had not, and invited him to see the process a second time. He minutely examined the water and the materials, which were...
198 psl. - A table of the circles arising from the division of a unit, or any other whole number,, by all the integers from 1 to 1024 ; being all the pure decimal quotients that can arise from this source.
254 psl. - I have seen the water run like a constant fountain stream forty feet high ; one vessel of water rarefied by fire driveth up forty of cold water. And a man that tends the work is but to turn two cocks, that one vessel of water being consumed, another begins to force and re-fill with cold water, and so successively, the fire being tended and kept constant, which the self-same person may likewise abundantly perform in the interim between the necessity of turning the said cocks.
431 psl. - ... frightened some of the guides. A very small quantity was sufficient to satisfy our thirst, for nine of us were perfectly satisfied with the contents of one bottle, and happily its unpleasant effects were but of short duration. The most peculiar sensation, which all have felt who have gained this great height, arises from the awful stillness which reigns, almost unbroken even by the voice of those speaking to one another; for its feeble sound can hardly be heard. It weighs deeply upon the mind,...
447 psl. - The poor beetle, which we tread upon, In corporal sufferance feels a pang as great As when a giant dies.
80 psl. - Nor are such the only opponents of great enterprises : there are some men, of narrow views and grovelling conceptions, who, without the instigation of personal malice, treat every new attempt as wild and chimerical, and look upon every endeavour to depart from the beaten track as the rash effort of a warm imagination, or the glittering speculation of an exalted mind, that may please and dazzle for a time, but can produce no real or lasting advantage.
60 psl. - I am apprehensive, that even good men are prone to pay less attention to the works of creation and providence than piety demands, and the Scriptures require. We say and hear so much concerning the insufficiency of these works to unfold the character of God, and the nature of genuine religion, that we are prone to consider them as almost uninstructive in moral things, and in a great measure useless to the promotion of piety. This, however, is a palpable and dangerous error. The works alone, without...
