The stars have on this theory random peculiar motions in addition to the motion of the drift to which they belong, just as on the older theory the stars have peculiar motions in addition to the solar or parallactic motion shared by all of them.
The systematic tendency of the proper motions is so marked that the motions of a very few stars are quite sufficient to fix roughly the position of the solar apex; but attempts to fix its position to within a few degrees have failed, notwithstanding the many thousands of determined proper motions now available.
The Taurus solar interpretation of the sign goes back to the far off time when the year began with Taurus, and the sun was conceived of as a bull entering upon the great furrow of heaven as he ploughed his way among the stars.
The theoretical element is the ratio of the parallactic inequality to the solar parallax.
The third and twelfth labours may be solar, the horned hind representing the moon, and the carrying of Cerberus to the upper world an eclipse, while the last episode of the hero's tragedy is possibly a complete solar myth developed at Trachis.
The third Galilean satellite is the largest moon in the solar system.
The warming of the ocean is due practically to solar radiation alone; such heat as may be received from the interior of the earth can only produce a small effect and is fairly uniformly distributed.

There ensued forty-five years of groping for a law which should clear up the enigma of the solar reversals.
There is a close interdependence between the constant of procession and Lhe solar motion; the two determinations must generally be made simultaneously, and both depend very considerably on the systematic corrections required by the catalogues compared.
There is every reason to assume, therefore, that the cult of Marduk existed already at this early period, though it must always be borne in mind that, until the days of Khammurabi, his jurisdiction was limited to the city of which he was the patron and that he was viewed solely as a solar deity.
There is for example some evidence that the declination of the solar apex is really increased when the motion is referred to fainter stars.
There is no a priori reason to expect the same result from the different classes of stars, such as the brighter or fainter, northern or southern, nearer or more distant, Solar type or Sirian stars.
There was a lunar mythology extant long before it was known that the lunar orb was a reflector of the solar light.

They were dedicated to solar deities, and were especially numerous at Heliopolis, where there was probably a single one sacred to the sun of immemorial antiquity.
They were published by the Board of Longitude, together with his solar tables, in 1770.
They were, on the other hand, probably acquainted, a couple of millenniums before Meton gave it his name, with the nineteen-year cycle, by which solar and lunar years were harmonized; 1 they immemorially made observations in the meridian; regulated time by water-clocks, and used measuring instruments of the nature of armillary spheres and quadrants.
This action was unconstitutional, and was bitterly resented by the vice-president Solar, who by right should have succeeded to the office.
This appears to be the explanation of Stumpe's and Porter's results; they both divided their proper motions into groups according to their numerical amount, and found that the declination of the solar apex progressively increased as the size of the motions used diminished.
This Differed From The Solar Year By Ten Whole Days And A Fraction; But, To Restore The Coincidence, Numa Ordered An Additional Or Intercalary Month To Be Inserted Every Second Year Between The 23Rd And 24Th Of February, Consisting Of Twenty Two And Twenty Three Days Alternately, So That Four Years Contained 1465 Days, And The Mean Length Of The Year Was Consequently 3664 Days.

This is an upper layer in the solar atmosphere called the chromosphere.
This is of course that relative motion of the sun and stars which we have previously called the solar motion.
This may be taken either in a refined sense, as if Aditi were the " infinite " region from which the solar deities rise,' or we may hold with the Taittirya-Brahmana' that Aditi was a female who, being desirous of offspring, cooked a brahmandana offering for the Sadhyas.
This Method Of Forming The Epacts Might Have Been Continued Indefinitely If The Julian Intercalation Had Been Followed Without Correction, And The Cycle Been Perfectly Exact; But As Neither Of These Suppositions Is True, Two Equations Or Corrections Must Be Applied, One Depending On The Error Of The Julian Year, Which Is Called The Solar Equation; The Other On The Error Of The Lunar Cycle, Which Is Called The Lunar Equation.

We have already seen that the year 1 of the era had Io for its number in the solar cycle, 2 in the lunar cycle, and 4 in the cycle of indiction; the question is therefore to find a number such, that Iv.
We might conceive the rapid motions of the heavenly bodies to result in some change either in the direction or amount of their gravitation towards each other at each moment; but such is not the case, even in the most rapidly moving bodies of the solar system.
We must content ourselves by referring to the progress of physical (including chemical) theory, which has led to the great generalization of the conservation of energy; to the discovery of the fundamental chemical identity of the matter of our planet and of other celestial bodies, and of the chemical relations of organic and inorganic bodies; to the advance of astronomical speculation respecting the origin of the solar system, &c.; to the growth of the science of geology which has necessitated the conception of vast and unimaginable periods of time in the past history of our globe, and to the rapid march of the biological sciences which has made us familiar with the simplest types and elements of organism; finally, to the development of the science of anthropology (including comparative psychology, philology, &c.), and to the vast extension and improvement of all branches of historical study.

When this distance is compared with those prevailing in the solar system, it seems an extraordinarily small separation between two such large bodies; we shall, however, presently come across systems in which the two components revolve almost or actually in contact.
Whether any earlier attempt was made to adjust the civil to the solar or Sothic year in order to restore the festivals to their proper places in the seasons temporarily or otherwise, is a question of great importance for chronology, but at present it remains unanswered.
