Page 65 - The PRESIDENT then delivered his Address, (p. 65.) It was proposed by Mr. LATHAM, seconded by Mr. FIELD, and resolved:— " That the thanks of the Society be given to the President for his Address, and that he be requested to allow it to be printed in the Quarterly Journal of the Society.
Page ix - Boyle's law that the product of the pressure and volume of a gas is constant for the same temperature.
Page 52 - The ohm is to be represented by a column of mercury of a square millimetre section at the temperature of zero Centigrade. 4. An international commission is to be appointed to determine, for practical purposes, by fresh experiments-, the length of a column of mercury of a square millimetre section which is to represent the ohm. 5. The current produced by a Volt through an Ohm is to be called an Ampere. 6. The quantity of electricity given by an Ampere in a second is to be called a Coulomb. 7. The...

Curiously enough, the flesh of a salmon affected by the disease presents no difference in texture or colour from that of a healthy fish, and those who have made the experiment declare that the flavour is just as good in the former case as in the latter. When the slough-like substance from the white patches above referred to is subjected to microscopical...
Page 383 - The aqueous vapour in the air would be similarly maintained as to its density, and its influx to, or reflux from, our atmosphere would be determined by the surface temperature of our earth. It is also important to show how the phenomena of comets could be...

These gases would issue forth in all directions, but would remain unobserved except in that of motion, in which they would meet the interplanetary atmosphere with the compound velocity, and form a zone of intense combustion, such as Dr. Huggins has lately observed to surround the one side of the nucleus, evidently the side of forward motion. The nucleus would thus emit original light, whereas the tail may be supposed to consist of stellar dust rendered...
Page 383 - It appears evident that the entry of such a divided mass into a comparatively dense atmosphere must be accompanied by a rise of temperature by frictional resistance, aided by attractive condensation. At a certain point the increase of temperature must cause ignition, and the heat thus produced must drive out the occluded gases, which in an atmosphere...
Page 375 - If the sun were surrounded by a solid sphere of a radius equal to the mean distance of the sun from the earth (95,000,000 of miles), the whole of this prodigious amount of heat would be intercepted ; but considering that the earth's apparent diameter as seen from the sun is only seventeen seconds, the earth can intercept only the 2250-millionth part.
