...imponderable forces ; celestial dynamics, by the power of gravitation ; the sweet vicissitude of the seasons, by the inclination of the earth's axis to the plane of its orbit ; the architecture of a plant, by electricity and other influences. This principle, in all its unphilosophical...

...Messrs. Jones, Holborn, London, which conveys a pretty clear idea of the motions and phases of the moon, the inclination of the earth's axis to the plane of its orbit, and the changes of the seasons. It may be procured at different prices, from I/. 8s. to 4/. 14s. Qd.,...

...next endeavor to explain to you the phenom ena of the Seasons. These depend on two causes ; first, the inclination of the earth's axis to the plane of its orbit ; and, secondly, to the circumstance, that the axis always remains parallel to itself. Imagine to yourself...

...into light and shade, or into day and night. THE CHANGE OF SEASONS. The change of seasons is produced by the inclination of the earth's axis to the plane of its orbit, as shown by the inclination of the axis of the globe. Illustration. The change of the seasons may be...

...what it saya about the seasons, child." " It says, sir, that the changes in the seasons are owing to ' the inclination of the earth's axis to the plane of its orbit.' I do not exactly understand what that means, uncle.1 " No, — it 's not as clear as it might be. —...

...the horizon. These two causes produce the warm season, or Summer, and are themselves the result of the inclination of the Earth's axis to the plane of its orbit, and the invariable parallelism of this inclination in all parts of the Earth's orbit. This inclination...

...all places on the same meridian, and midnight to all places on the opposite meridian. 126. Owing to the inclination of the earth's axis to the plane of its orbit, certain portions of its surface are brought successively under the vertical rays of the sun, the limits...

...(148.) In order farther to explain the differences of the length of the solar day we will now consider the inclination of the earth's axis to the plane of its orbit. This inclination is an important cause of the differences in the length of the solar day. Were the...

...this relative nearness or distance of the sun ought naturally to produce. Such a cause is found in the inclination of the earth's axis to the plane of its orbit. The effect of this arrangement can be easily illustrated by an impromptu orrery. Let a card placed...

...the celestial equator crosses the ecliptic, and the angle formed by these lines is always equal to the inclination of the earth's axis to the plane of its orbit. These points are formed every year about fifty seconds farther west of where they were the previous...
