Note 2 — THE INTRODUCTION, CONTAINING
Reading edition
N. B. According to Biachini’s Observations, Venus’s axis inclines 75 degrees from the perpendicular to the plane of the Ecliptic (which is 51½ deg. more than the axis of our Earth) her Tropics are only 15 deg. from her Poles, and her Polar Circles at the same distance from her Equator; so that the Sun’s greatest Declination on each side of her Equator is 75 deg. by which she must undergo a much greater variety of seasons than we do on our Earth.
