...Climate and the Rate of Oryanio (Change. By ALFBED E. WALLACE, FRQS The author exhibited a diagram of the eccentricity of the earth's orbit and the precession of the equinoxes, from which he deduced certain importent views as to the climates of past geological ages and the changes...

...and the líate of Organic Change. By ALFRED E. WALLACE, F.Ii.&.S, The author exhibited a diagram of the eccentricity of the earth's orbit and the precession of the equinoxes, from which he deduced certain important views as to the climates of past geological ages and the changes...

...views, refuse to attach any importance which they may seem to require to astronomical cycles affecting the eccentricity of the earth's orbit and the precession of the equinoxes, or to the possible diminution or inequality of solar energy, or to the secular cooling and contraction...

...chilling of the temperature at either Pole. Perhaps the effect was wholly due, as Dr. Croll believes, to the eccentricity of the earth's orbit and the precession of the equinoxes ; perhaps it was further aided, as Mr. Wallace suggests, by the elevation of great mountain ranges...

...given in the astronomy books, I get so muddled up with the ' ' inclination of the earth's axis," " the eccentricity of the earth's orbit," and " the precession of the equinoxes " — but I am not quite sure this last thing has anything to do with it Anyhow, I wish to tell you...

...would receive ; so that there could be no such continuity of cold as would produce a thick ice-cap. To the eccentricity of the earth's orbit and the precession of the equinoxes, Mr. Croll adds changes in the obliquity of the ecliptic as a third factor ; and which he thinks in...

...however, was not due to terrestrial changes alone so much as the result of cosmical causes dependent on the eccentricity of the earth's orbit, and the precession of the equinoxes, combined with changes in the obliquity of the ecliptic, and nutation, a small gyratory, nodding, conical...

...Commissioners, with a wisely liberal relaxation of their rules, accepted his great calculations regarding the eccentricity of the earth's orbit and the precession of the equinoxes during the last ten million years as sufficient evidence of his arithmetical capacity, and his book...
