Page 202 - There are no such breaks corresponding to the consonants : the vibrations of the consonants glide on as smoothly as those of the vowels. The number of waves producing a word is sometimes enormous. In "Constantinople " there may be 500, or 600, or 800 vibrations. A record of the words " Royal Society of Edinburgh...
Page 119 - ... unless the contrary is expressly stated. A finite portion of liquid, viscid or inviscid, being given at rest, within a bounding vessel of any shape, whether simply or multiply continuous; let any motion be suddenly produced in some part of the boundary, or throughout the boundary, subject only to the enforced condition of unchanging volume. Every particle of the liquid will instantaneously commence moving with the determinate velocity and in the determinate direction, such that the kinetic energy...
Page 419 - THERMODYNAMICS glass stopcocks very slightly, allow the desired quantities of the liquids to enter, and close them again. They will not be opened again unless there is occasion to remove the whole or some part of the liquid from either bottle; and, unless explicitly mentioned, will not be included among the stopcocks referred to in what follows. It will generally be convenient to make the quantities of the two liquids introduced such that they stand at as nearly as may be the same levels in the two...
Page 326 - If, for example, there are 1000 S molecules to one D molecule in the space A, the pressure on the piston P would be 1001 times the osmotic pressure, and on Q 1000 times the osmotic pressure. But if the fluid be "liquid" on both sides of the membrane, we may annul the pressure on Q and reduce the pressure on P to equality with the osmotic pressure, by placing the apparatus under the receiver of an air-pump, or by pulling Q outwards with a force equal and opposite to the atmospheric pressure on it.
Page 327 - Avogadro's law of gases, has manifestly no theoretical foundation at present ; even though for some solutions other than mineral salts dissolved in water, it may be found somewhat approximately true; while for mineral salts dissolved in water it is wildly far from the truth. The subject is full of interest, which is increased, not diminished, by eliminating from it fallacious theoretical views. Careful consideration of how much we can really learn with certainty from theory (of which one example...
Page 119 - This proposition is also true for an incompressible elastic solid, manifestly (and for the ideal "ether" of Proc. RSE, March 7 1890 ; and Art. xcix. vol. III. of my Collected Mathematical and Physical Papers). The truth of the proposition for the case of a viscous liquid is very important in practical hydraulics. As an example of its application to inviscid and viscous fluid and to elastic solid, consider an elastic jelly standing in an open rigid mould, and equal bulks of water and of an inviscid...
Page 164 - ... of the investigation when written out in Cartesian form (which I began doing, but gave up aghast), some abbreviated method of expression becomes desirable. I may also add, nearly indispensable, owing to the great difficulty in making out the meaning and mutual connections of very complex formulae. In fact the transition from the velocity-equation to the wave-surface by proper elimination would, I think, baffle any ordinary algebraist, unassisted by some higher method, or at any rate by some kind...
Page 519 - Report on the search for Sanskrit MSS. in the Bombay Presidency during the year 1882-83.
Page 202 - ... less length of wave according to the pitch of the sound. The consonantal sounds of the word are breaks, as it were, in the stream of air issuing from the oral cavity, and these breaks, owing to labial, dental, buccal, or glossal vibrations, produce sounds that have also often the musical character of vowels. Thus at the beginning of " Constantinople" we have, as will be observed on pronouncing the syllable very slowly, the sound Ulcko.
