Page 153 - J oz. in pan sufficed. From these results it appears that the friction is greater with a large dose than with a minute quantity of the same oil, and this is what is hard to explain.
Page 264 - ... to the tissues. From these it receives in exchange their waste products, namely, carbon dioxide and the results of nitrogenous metabolism, and carries them away to the excretory organs, such as the lungs and kidneys, by which they are eliminated. It is evident that the composition of the blood must vary from time to time and place to place according to the condition of activity and the function of the organ which it is traversing. The organs of the body are adjusted to respond to very minute...
Page 246 - IN the previous communication a general account of the results which have been obtained, up to the present time, on the resonance spectra of iodine has been given.
Page 42 - B, by means of which it is condensed on the aperture of the diaphragm C. The diverging beam of light is collimated by a lens D, and falls as a parallel beam on a plane parallel plate K, the second surface of which is silvered lightly so that a part of the Fig.
Page ii - Vol. xxn. p. 39 (1913). so. As an alternative to an inclined plane surface, consideration is given to a. broken surface consisting of two parts, each of which is parallel to the first plane surface but at a different distance from it. It appears that this is the form which must be approached if we wish the total pressure supported to be a maximum, when the length of the bearing and the closest approach are prescribed. In these questions we may anticipate that our calculations correspond pretty closely...
Page 131 - Nimrud and the other numerous volcanoes of Armenia came into existence at a period when the sedimentary rocks could no longer be folded, but were fractured along definite lines, and Nimrud is situated on the great fracture transverse to the Armenian folds at the apex of their bending round from the...
Page 156 - Wellenberuhigurig," •by MM Richter (see NATURE, vol. xlix. p. 488), the opinion is expressed that the tendency of oil to spread itself on water is only due to the free oleic acid contained in it, and that if it were possible to completely purify the oil from oleic acid, it would not spread at all. This I found to be actually the ca<e with olive oil, and though I agree by no means with the theoretical...
Page 103 - The investigation was carried out in the Physical Laboratory of the Indian Association for the Cultivation of Science, Calcutta, and the writer's best thanks are due to Prof.
Page 154 - J, we see that the phenomena here in question probably lie outside the field of the usual theory of lubrication, where the layer of lubricant is assumed to be at least many molecules thick. We are rather in the region of incipient seizing, as is perhaps not surprising when we consider the smallness of the surfaces actually in contact.
