The ancient Hindus observed that the Zodiac went forward at about the rate of fifty‐four seconds a year, and to avoid greater fractions, stated it at that, which would make a complete round in 24,000 years; and observing the angle of the poles to vary nearly 4 degrees each round, stated the three numbers as such, which would have given _forty‐five rounds of the Zodiac_ to half a revolution of the poles; but finding that forty‐five rounds would not bring the northern tropic to coincide with the circle of perpetual apparition by thirty minutes of a degree, which required the Zodiac to move one sign and a half more, which we all know it could not do in less than 3,000 years, they were, in the case before us, added to the end of the _brazen age_; which lengthen the reign of _that_ Yudhister to 27,000 years instead of 24,000, but, at another time they did not alter the regular order of 24,000 years to the reign of each of these long‐winded monarchs, but rounded up the time by allowing a _regency_ to continue three or four thousand years. In volume ii. p. 134, _Asiatic Researches_, we are told that: “Paricshit, the great nephew and successor of Yudhister, is allowed without controversy to have reigned in the interval between the _brazen and earthen_, or Cali Ages, and to have died at the setting‐in of the Cali Yug.” Here we find an _interregnum_ at the _end_ of the _brazen_ age, and _before_ the setting‐in of the Cali Yug: and as there can be but one brazen or Treta Yug, _i.e._, the third age, in a Maha Yuga of 1,080,000 years: the reign of this Paricshit must have been in the second Maha Yuga, when the pole had returned to its original position, which must have taken 2,160,000 years: and this is what the Hindus call the Prajanatha Yuga. Analogous to this custom is that of some nations more modern, who, fond of even numbers, have made the common year to consist of twelve months of thirty days each, and the five days and odd measure have been represented as the reign of a little serpent biting his tail, and divided into five parts, etc. But “Yudhister began his reign immediately _after the flood called Pralaya_,” _i.e._, at the end of the Cali Yug (or age of heat), when the tropic had passed from the pole to the other side of the circle of perpetual apparition, which coincides with the northern horizon; here the tropics or summer solstice would be again in the same parallel of north declination, at the _commencement_ of their first age, as he was at the _end_ of their _third age_, or Treta Yug, called the brazen age.... Enough has been said to prove that the Hindu books of science are not disgusting absurdities, originated in ignorance, vanity, and credulity; but books containing the most profound knowledge of astronomy and geography.
