Página 358 - Before discussing the conclusions to which the facts already stated seem directly to point, it will be well to see how far the variation in composition corresponds to a variation in the properties of the two compounds. Three classes of properties have been examined in this connection, viz., Specific Gravity, Crystalline Form, and Affinity for Oxygen, which will be treated of in order.
Página 256 - ... gravities in the gaseous state can be easily expressed algebraically, since in each series the quotient of the specific gravity divided by the atomic weight is a constant quantity. As an illustration, we may take the series of binaries homologues of water given in the Nine Series of our table. It follows from what has been said, that the atomic weights of these compounds equals 9 + n 9.
Página 247 - Arsenic. The ordinary condition of Phosphorus is its monometric modification, while the rhombic state seems to be the normal condition of Arsenic, Antimony, and Bismuth. Now the atomic weights of the last three are either equal to, or slightly exceed, the theoretical number, while that of the first fall short, perhaps even by a unit. Other facts, which also tend to show that the deviations are not matters of chance, may be found in the affiliations of the series. There are some elements which seem...
Página 116 - Encke, with perfect distinctness, divided into two nearly equal parts, and several divisions were recognized on the inner edge of the inner ring. The great equatorial of the Berlin Observatory was used with an achromatic eyepiece. On the 28th of May, the place of the outer secondary interval was determined. The great optical capacity of the telescope, and the eminence of Professor Encke as an observer, give the highest value to these observations. They are found in ihe Astr.

Página 177 - The whole effect produced, and to my own mind well and clearly defined, was precisely what we should have if we could suddenly place in a vacuum a building filled with atmospheric air of ordinary tension. Even the foundation walls were inclined outwards, and there was -•% every evidence of a force acting from the interior to the exterior.
