Pàgina 634 - 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 iuto it. Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent...
Pàgina 507 - The times have been That, when the brains were out, the man would die, And there an end ; but now they rise again, With twenty mortal murders on their crowns, And push us from our stools.
Pàgina 631 - A particle of oxygen is ever a particle of oxygen — nothing can in the least wear it. If it enters into combination and disappears as oxygen, — if it pass through a thousand combinations, animal, vegetable, mineral, — if it lie hid for a thousand years and then be evolved, it is oxygen with its first qualities, neither more nor less.
Pàgina 308 - ... oxygen ; so that the whole heat of the system must still be referred to the chemical changes. But if the animal were engaged in turning a piece of machinery, or in ascending a mountain, I apprehend that in proportion to the muscular effort put forth for the purpose, a diminution of the heat evolved in the system by a given chemical action would be experienced.
Pàgina 315 - I have said on this subject has been derived from him. When we consider the circumstances of Mayer's life, and the period at which he wrote, we cannot fail to be struck with astonishment at what he has accomplished. Here was a man of genius working in silence, animated solely by a love of his subject, and arriving at the most important results, some time in advance of those whose lives were entirely devoted to Natural Philosophy.
Pàgina 780 - Two similar effects, the one arising from a local irritation, and the other from the presence of Belladonna, like spreading circles on a smooth sheet of water, interfere with and neutralise each other.
Pàgina 307 - Among the practical conclusions which may be drawn from the convertibility of heat and mechanical power into one another, according to the above absolute numerical relations, I will content myself with selecting two of the more important. The former of these is in reference to the duty of steam-engines; the latter, to the practicability of employing electro-magnetism as an economical motive force.
Pàgina 307 - I shall lose no time in repeating and extending these experiments, being satisfied that the grand agents of nature are, by the Creator's fiat, indestructible ; and that wherever mechanical force is expended, an exact equivalent of heat is always obtained.
Pàgina 120 - Therefore disease (that does not come within the province of manual surgery) considered, as it is by the allopathists, as a thing separate from the living whole, from the organism and its animating vital force, and hidden in the interior, be it of ever so...
Pàgina 304 - In 1840 he published the important result that 'when a current of voltaic electricity is propagated along a metallic conductor, the heat evolved in a given time is proportional to the resistance of the conductor multiplied by the square of the electric intensity.
