Página 9 - ... point de variation sensible, la conservation de la chaleur animale est due, au moins en grande partie, à la chaleur que produit la combinaison de l'air pur respiré par les animaux avec la base de. l'air fixe que le sang lui fournit.
Página 11 - ... expressed his belief that the blood was driven through the vessels by the mechanical action of the heart, or that respiration took place according to the common laws of the diffusion of gases. The present generation, on the contrary, is hard at work to find out the real causes of the processes which go on in the living body. They do not suppose that there is any other difference between the chemical and the mechanical actions in the living body, and out of it, than can be explained by the more...
Página 9 - La respiration est donc une combustion, à la vérité fort lente, mais d'ailleurs parfaitement semblable à celle du charbon; elle se fait dans l'intérieur des poumons, sans dégager de lumière sensible, parce que la matière du feu, devenue libre, est aussitôt absorbée par l'humidité de ces...
Página 9 - ... how large a quantity of heat might be produced, by proper mechanical contrivance, merely by the strength of a horse, without either fire, light, combustion, or chemical decomposition; and, in a case of necessity, the heat thus produced might be used in cooking victuals.
Página 11 - Whence it appears that one-quarter of the whole amount of vis viva generated by the combustion of food in the animal frame is capable of being applied in producing a useful mechanical effect, — the remaining three-quarters being required in order to keep up the animal heat, etc.
Página 9 - ... proper mechanical contrivance, merely by the strength of a horse, without either fire, light, combustion, or chemical decomposition; and, in a case of necessity, the heat thus produced might be used in cooking victuals. But no circumstances can be imagined in which this method of procuring heat would not be disadvantageous; for more heat might be obtained by using the fodder necessary for the support of a horse, as fuel.
Página 11 - The majority of the physiologists in the last century, and in the beginning of this century, were of opinion that the processes in living bodies were determined by one principal agent which they chose to call the " vital principle." The physical forces in the living body they supposed could be suspended or again set free at any moment, by the influence of the vital principle ; and that by this means this agent could produce changes in the interior of the body, so that the health of the body would...
Página 9 - ... cette combustion se communique au sang qui traverse les poumons, et de là se répand dans tout le système animal. Ainsi l'air que nous respirons sert à deux objets, également nécessaires à notre conservation : il...
