الصفحة 123 - ... l'aveu de tout le monde, la quantité de mouvement que le corps perd à chaque instant est proportionnelle au produit de la résistance par la durée infiniment petite de l'instant, et que la somme de ces produits est évidemment la résistance totale. Toute la difficulté se réduit donc à savoir si on doit mesurer la force par la quantité absolue des obstacles, ou par la somme de leurs résistances. Il...

The negative energy of the copper and the positive energy of the zinc are consequently again exerted, enfeebled only by the opposing energy of the soda in contact with the copper, and the process of electromotion continues, as long as the chemical changes are capable of being carried on.
الصفحة 32 - ... extinction of flame in the same circumstances; and when once any quantity of air has been rendered noxious by animals breathing in it as long as they could, I do not know that any methods have been discovered of rendering it fit for breathing again. It is evident, however, that there must be some provision in nature for this purpose, as well as for that of rendering the air fit for sustaining flame; for without it the whole mass of the atmosphere would, in time, become unfit for the purpose of...
الصفحة 338 - The water discharged by it, falls immediately into a stone trough; in the front of which are two holes near the bottom; these are the outlets of two streams, that flow constantly from the artificial cistern. An oblong notch is also cut in the same side of the trough; which extends from the brim of it, nearly to the level of the two holes already mentioned. This aperture is intended to shew the fluctuations of the well: for the water subsides in it, when...
الصفحة 122 - ... mouvement, peut représenter la force. Tout le monde convient aussi que, dans le mouvement retardé, le nombre des obstacles vaincus est comme le carré de la vitesse; en sorte qu'un corps qui a fermé un ressort, par exemple, avec une certaine vitesse, pourra avec une vitesse double fermer, ou tout à la fois, ou successivement, non pas deux, mais quatre ressorts semblables au premier, neuf avec une vitesse triple, et ainsi du reste.

الصفحة 35 - When the influence of the brain is cut off, the secretion of urine appears to cease, and no heat is generated; notwithstanding the functions of respiration and the circulation of the blood continue to be performed, and the usual changes in the appearance of the blood are produced in the lungs. " 4. When the air respired is colder than the natural temperature of the animal, the effect of respiration is not to generate, but to diminish animal heat.
