Էջ 8 - That gravity should be innate, inherent and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else by and through which their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall into it.
Էջ 8 - Gravity must be caused by an agent acting constantly according to certain laws, but whether this agent be material or immaterial I have left to the consideration of my readers.
Էջ 93 - Whatever is intended for insertion must be authenticated by the name and address of the writer ; not necessarily for publication, but as a guaranty of good faith. We do not hold ourselves responsible for any view or ooinions expressed in the communications of our correspondents. Attention is called to the "Wants
Էջ 8 - It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, in the sense of Epicurus, be essential and inherent in it.
Էջ 148 - Act confirming such provisional order, or of such special Act, and within six months after the expiration of every subsequent period of seven years, or such shorter...
Էջ 148 - ... position as to be ready for immediate working, and to the suitability of the same to the purposes of the undertaking, and. where a part only of the undertaking is purchased, to any loss occasioned by severance: but without any addition in respect of compulsory purchase, or of goodwill, or of any profits which may or might have been or be made from the undertaking, or of any similar considerations.
Էջ 148 - ... may within six months after the expiration of a period of twenty-one years from the...
Էջ 193 - It has long been known that when a permanent magnet is caused to approach the pole of an electro-magnet a current of electricity is induced in the coils of the latter, and that when it is made to recede a current of opposite polarity to the first appears upon the wire.
Էջ 193 - The reciprocal vibration of the elements of a battery, therefore, occasions an undulatory action in the voltaic current. The external resistance may also be varied. For instance, let mercury or some other liquid form part of a voltaic circuit, then the more deeply the conducting-wire is immersed in the mercury or other liquid, the less resistance does the liquid offer to the passage of the current. Hence, the vibration of the conducting-wire in mercury or other liquid included in the circuit occasions...
Էջ 85 - I find a frank acknowledgment of one's ignorance is not only the easiest way to get rid of a difficulty, but the likeliest way to obtain information, and therefore I practise it ; I think it an honest policy.
