Page 414 - well as the external outline of our globe, are elliptical, their centres being coincident, and their axes identical with that of the surface,—a state of things incompatible with a subsequent accommodation of the surface to a new and different state of rotation from that which determined the original distribution of the component matter.
Page 327 - which defy all such methods of examination, and which will yield only to the magical analysis of polarized light. A body which is quite transparent to the eye, and which appears upon examination to be as monotonous in its structure as it is in its aspect, will yet exhibit under polarized light the most exquisite organization,
Page 430 - same number of atoms combined in the same way produces the same crystalline form, and the same crystalline form is independent of the chemical nature of the atoms, and is determined only by their number and relative

Supposing they all acquired the same degree of solar heat which was thus converted into heat of temperature, and then radiated from the surfaces as simple heat, the real conclusion established is, that the RADIATING powers of surfaces for simple heat are in the inverse order of their conducting powers.
Page 158 - for 1816, Burckhardt gave the results of a comparison of Delambre's Tables with a great number of Maskelyne's observations (far greater than the number on which they were founded). It appeared that the epoch, the perigee, and the eccentricity, required sensible alterations, and that the mass of Venus ought to be reduced about
