 ``` 2o6 ALBERUNTS INDIA. If the moon stands in the eveoi quarters of the ecliptic (i.e. the summer and winter quarters), just the reverse takes place. Another Pulisa adds together the declinations of sun and Pulisa. ^ moon in vyattpdta, if they stand on different sides of the solstice, and in 'oaidhritct, if they stand on the same side of the solstice. Further, he takes the difference between the declinations of sun and moon in vycttipdtct, if they stand on the same side, and in vaidhritct, if they stand on different sides. This is the first value which is kept in memory, i.e. the middle time. Further, he reduces the minutes of the days to mdshas, supposing that they are less than one-fourth of a day. Then he computes their motions by means of the hhukti of sun and moon and the dragon's head and tail, and he computes their places according to the amount of middle time, which they occupy, in the past and the future. This is the second value which is kept in memory. By this method he manages to find out the condition of the past and the future, and compares it with the middle time. If the time of the two declinations equalling each other for both sun and moon is past or future, in that case the difference between the two values kept in memory is the portio divisionis (divisor) ; but if it is past for the one and future for the other, the sum of the two values kept in memory is the pjortio divisionis. p.ige 300. Further, he multiplies the minutes of the days,'which have been found, by the first value kept in memory, and divides the product by the portio divisionis. The quotient represents the minutes of the distance from the middle time which minutes may either be past or future. Thus the time of the two declinations equalling each other becomes known. The author of the canon Karctnatilaka makes us return to the arc of the declination which has been ```
