...is inclined to the plane of his orbit at an angle of 61° 18'. This quantity is very neariy equal to the inclination of the earth's axis to the plane of its orbit, and as the seasons depend in a measure upon this inclination, those of Mars are probably somewhat like...

...dark in reference to the cause of the intense cold of the glacial time. It has been suggested that the inclination of the earth's axis to the plane of its orbit, which is 23° 28', and is the cause of our present seasons, may have been so different during the glacial...

...of the wonderful results of what has been well called " the simple but stupendous contrivance " of the inclination of the earth's axis to the plane of its orbit ;— a contrivance, like the rest of God's works, full of wisdom and goodness, and well adapted to...

...; and was profound on this, the greatest concern of human life, while unable even to comprehend how the " inclination of the earth's axis to the plane of its orbit" could be the cause of the change of the seasons. And was it thus with her uncle ? — he who was a...

...apsides.1 This line is not always directed to the same point in the heavens, but revolves ; and as the inclination of the earth's axis to the plane of its orbit may be considered fixed, the tendency of this movement is to bring about the seasons at all parts of...
