...would account for it ; bub the periodical disturbances in the Earth's motion, and the secular variation of the inclination of the Earth's axis to the plane of the ecliptic produced by Venus, do not allow any such change in our estimate of her mass. On the other hand, a planet...

...This path ranges 23y2 degrees north and 23J/2 degrees south of the equator and is the measure also of the inclination of the earth's axis to the plane of the ecliptic. Reference to Fig. 1 shows us the positions of the earth in summer as well as in winter. Note the angle...

...hemisphere to the sun, as does the moon to the earth: and how immense is the benefit resulting to us from the inclination of the earth's axis to the plane of the ecliptic, without which we should have enjoyed no change of seasons, while those temperate regions which are...

...so uniform and continuous for hundreds or thousands of years as that of the changes of season due to the inclination of the earth's axis to the plane of the ecliptic ; and these changes imply a solar control. The evidences of drought, also, cannot be accounted for...

...species can attain dominance. ANNUAL SUCCESSION The annual revolution of the earth about the sun and the inclination of the earth's axis to the plane of the ecliptic produce a regularly recurring series of seasonal changes which are most pronounced near the poles and...

...scale, is bent round into a complete circle and becomes a model which can be interpreted as showing the inclination of the earth's axis to the plane of the ecliptic. These simple observations on the noonday shadow fall into the Nature-study period : we see their development...

...climate had been uniform since the creation and that there had been no variation of consequence in the inclination of the earth's axis to the plane of the ecliptic. Men, however, could make significant local changes. The contrasts, so typical of men of this period...

...in an ordinary spinning top, is extremely slow, with a period of roughly 26,000 years. In addition, the inclination of the earth's axis to the plane of the ecliptic changes very slightly; the period of this nutational disturbance is about 40,000 years. Further, the...
