FOMALHAUT -18.97 If the places of these stars are wanted for any time before the beginning of the year 1810, multiply the annual variation both in right ascension and declination, by the number of years before 1810, and subtract the product from the right ascension standing in the table; but the product of the annual variation in declination must be added to, or subtracted from the declination, with a contrary sign; but for any year after 1810, the variation in right ascension must be added to the right ascension in this table, and the variation in declination must either be added to, or subtracted from it, according as their signs are, to fit the declination to any succeeding year. The annual variation is set down for seconds, and decimals of a second. The ars in the preceding table will be found to correspond with those whose mes are marked in the planispheres.

EXAMPLE.
