Stranica 145 - The end of our foundation is the knowledge of causes, and secret motions of things; and the enlarging of the bounds of human empire, to the effecting of all things possible.
Stranica 142 - ... may not, some day, be artificially brought together. All I feel justified in affirming is, that I see no reason for believing that the feat has been performed yet. And, looking back through the prodigious vista of the past, I find no record of the commencement of life, and therefore I am devoid of any means of forming a definite conclusion as to the conditions of its appearance.
Stranica 137 - ... the mutual relations of Light to the Eye, and of the Eye to Light, were the same at the time when Crustaceans endowed with the faculty of vision were first placed at the bottom of the primeval seas, as at the present moment. Thus we find among the earliest organic remains, an Optical instrument of most curious construction, adapted to produce vision of a peculiar kind, in the then existing representatives of one great Class in the Articulated division of the Animal Kingdom. We do not find this...
Stranica 69 - For a clear understanding of the mechanism, elaborate drawings would be necessary. "We shall, therefore, merely give a general account of its construction and peculiarities : 1st. A system of clock-work carrying a type-wheel with fifty numbers on its rim, revolving once every second ; one, two, or parts of two numbers being always printed, so that hundredths of seconds may be indicated. This train is primarily regulated to move uniformly by the Frauenhaufer friction balls, and secondarily by an electro-magnet...
Stranica 71 - ... the hammer is acted on by gravity alone, the armature time will be sensibly uniform. The types are inked by means of small rollers, covered with cloth, resting against their rim, and revolving with the wheel by friction. These rollers require inking every two or three days. If desirable, the inking rollers may be dispensed with, and impression paper used instead. After numerous experiments made with both methods, we have preferred the ink. The paper fillet, two inches in width, is wound on a...
Stranica 213 - Bunsen's lamp threw the bright sodium lines upon the solar spectrum with unexpected brilliancy. In order to find out the extent to which the intensity of the solar spectrum could be increased without impairing the distinctness of the sodium lines, I allowed the full sunlight to shine through the sodium flame, and to my astonishment I saw that the dark lines D appeared with an extraordinary degree of clearness.
Stranica 112 - Poictou, three thousand men having taken up arms, and beaten the troops which were appointed to disperse them : three of the mutineers being taken, were immediately executed ; and as many of the King's party were used after the same manner. Our late act of naturalization hath had so great an effect in foreign parts, that some Princes have prohibited the French refugees in their dominions to sell or transfer their estates to any other of their subjects ; and at the same time have granted them greater...
Stranica 138 - ... 3d, The animals and plants of the present epoch are the derivatives, with modification of antecedent forms to an unlimited extent. 4th, An arrangement of organized beings in any single series is, therefore, impossible ; and the system of sequences adopted by genealogists may be applied to the sequence of the groups of natural objects. 5th, In the appreciations of the value of groups, the founder of modern taxonomy (Linnseus) must be followed, subject to such deviations as our increased knowledge...
Stranica 119 - Resolved that the inviting and bringing over into this kingdom the poor Palatines of all religions at the public expense was an extravagant and miserable charge to the kingdom, and a scandalous misapplication of the public money...
Stranica 23 - ... rare qualities of mind and character which have since raised him to the very first rank among the experimental philosophers of his time. Chemistry at that time was exciting great interest, and Dr. Beck's courses of chemical lectures, conducted every winter in the lecture room of the Academy, were attended not only by the students, but by all that was most intelligent and fashionable in the city. Henry, who had been formerly a pupil in the Academy, was then Dr. Beck's chemical assistant, and already...
