The True Places of the Plate:8 105 bum of the daily motions of the bwo planets: the result is the time in tदीdis What the yoga is, is evident from this rule for finding it; it is the period, of variable length, during which the joint notion in longitude of tblhe sun and moon amounts to 18° 20y the portion of a lunar unausion. According to Colebrooke (As. Res. , ix . 865; Essays, ii, 862, 86B), the use of the yoga is chiefly sitological; the occurrence of certain move. ble festivals is, however, also regulated by them, and they are so frequently employed that every Hindu almanac contains a column specifying the yoga. to ach day, whh the time of its termination.

Of this system the Surya-Siddhantan presents no trace.

The name yoga, by which this astrological period is called, is applied to it, apparently, as designating the period uring which the sum (yog). of the increments in longitude of the sum and moon amounts to a given quantity. It seems an entirely arbitrary device of the astrologers, being neither a natural period nor a subdivision of one, not being ot any use that we can discover in determining the relative position, or 14
