Сторінка xxii - The diffusion or spontaneous intermixture of two gases in contact, is effected by an interchange in position of indefinitely minute volumes of the gases, which volumes are not necessarily of equal magnitude, being, in the case of each gas, inversely proportional to the square root of the Density of that gas.
Сторінка xxiii - But, on the other hand, their peculiar physical aggregation with the chemical indifference referred to, appears to be required in substances that can intervene in the organic processes of life. The plastic elements of the animal body are found in this class.
Сторінка 357 - ... showed a more rapid contraction of the ventricles, but less power than in the alcoholic period. The brandy acted, in fact, on a heart whose nutrition had not been perfectly restored.
Сторінка 98 - Lamp, to be employed in founding a Medal to be given annually for the most important discovery in Chemistry made in Europe or Anglo-America.
Сторінка 356 - The first day of alcohol gave an excess of 4 per cent., and the last of 23 per cent. ; and the mean of these two gives almost the same percentage of excess as the mean of the six days. " Admitting that each beat of the heart was as strong during the alcoholic period as in the water period...
Сторінка 356 - The period of rest for the heart was shortened, though perhaps not to such an extent as would be inferred from the number of beats; for each contraction was sooner over.
Сторінка xxi - ... to find the value for this common coefficient of expansion. Berthollet had in 1809 demonstrated that hydrogen diffuses much more rapidly than any other gas; but it remained for Graham first to show, in 1828, that the diffusion of all gases is inversely as some function of their density, apparently the square root; and then to definitely establish, in 1838, that "the diffusion, or spontaneous intermixture, of two gases in contact, ... is, in the case of each gas, inversely proportional to the...
Сторінка 430 - from the Gulf of Mexico), if it reaches this locality at all — which is very doubtful — could only affect the most superficial stratum ; and the same may be said of the surface-drift caused by the prevalence of southwesterly winds, to which some have attributed the phenomena usually accounted for by the extension of the Gulf Stream to these regions.
Сторінка 359 - While we recognize in these experiments the great practical use of alcohol in rousing a failing appetite, exciting a feeble heart, and accelerating a languid capillary circulation, we have been strongly impressed with the necessity for great moderation and caution.
Сторінка 31 - The ordinary gaseous and ordinary liquid states are, in short, only widely separated forms of the same condition of matter, and may be made to pass into one another by a series of gradations so gentle that the passage shall nowhere present any interruption or breach of continuity.
