Not illustrated. 1846 Excerpt: ...the two causes which prevent the coincidence of the sun and clock. By the first cause, which is the inclination of the earth's axis, they would agree four times in the year; and by the second cause, the irregularity of the earth's motion, they would coincide only twice in the year. Now, these two causes counteract the effects of each other, so that the sun and clock do not coincide on any of the days, when either cause, taken singly, would make an agreement between them. The sun and clock, therefore, are together, only when the two causes balance each other; that is, when one cause so counteracts the other, as to make a mutual agreement between them. This effect is produced four times in the year; namely, on the 15th of April, 15th of June, 31st of August, and 24th of December. On these days, the sun, and a clock keeping exact time, coincide, and on no others. The greatest difference between the sun and clock, or between the apparent and mean time, is 16-J-minutes, which takes place about the 1st of November. PRECESSION OT THE EQUINOXES. 156. "A tropical year is the time it takes the sun to pass from one equinox, or tropic, to the same tropic, or equinox, again. A sidereal year is the time it takes the sun to perform his apparent annual revolution, from a fixed star, to the same fixed star again. 154. At what times would the form of the earth's orhit bring the sun and clock to agree?--155. The inclination of the earth's axis would make the sun and clock agree four times in the year, and the form of the earth's orbit would make them agree twice in the year; now show the reason why they do not agree from these causes on the above-mentioned days, and why they do agree on other days? On what days do the sun and clock agree?--156. What is a tropical year? W...
