80 difference between the daily motions (of the Sun and Moon) and divide by 51570 : the result is (the 10t) in minutes of arc, etc The nati means the difference between the parallaxes in latitude of the Sum and Moon. We have (uide MBl, v. 28) Moon's parallax in latitude drk:$920 x Earth's semi-diameter in 19jaras Moon's true distance in ygjaras But, as before, Parth's semi-diameter in 19jाmas Moon's true distance in y१jamas Therefore Moon's parallax in latitude 15 x 3438 Similarly, Sun's parallax in latitude dkg०)0 x Sun's true daily motion 15 x 3438 ence d. *}60 [Moon's true daily motion- 15 x 3438 525 79058 x 3438 Moon's true daily motion in minutes of arc 15 x 3438 ०i. Sum and Moon) 51570 525 ] In the above rationale we have assumed that 7905*83 525 1ikewise taken But this is incorrect, because Iminutes. 51770 Sun's true daily motion]].
