N. B. la the above table, the meafure at 2^^-37'. 40^' 

 was taken between the neareft limb of the Sun and the in- 

 terior limb of Mercury neareft to the Sun's center, and is

/ 



the fame with the diftance of their neareft 



limbs at 3 



// 



So alfo the diftance between the 



2"202, 



nearcl^ limb of the Sun, and the interior limb of Mer- 

 cury, at 3^- 41'. 10", was the fame with the diftance of 

 their neareft limbs at 3^- 42'. 50'^ viz, 5'. 21 '',406. 

 fame is to be faid of the laft meafure, which was taken 

 from the neareft limb of the Sun to the limb of Mercury 

 neareft to the Sun's center.

If a computation be made from the above meafures, the 

 arent neareft diftance of their centers will be found to 



app 



be 45X^^9I4' But Mercury was then deprefled by paral- 

 lax 3^',! I ; fo that the geocentric neareft approach of their 

 centers was 455'\o24,. which happened at 5^'- i'. 15" ap- 

 parent time, when his par. in the vert, was 4^,042, and in 

 his path 2%S3y ^^'^^^ perpend, to his path 3'',ii. 



The horary motion of Mercury as fecn from the Earth 

 is alfo determined from the above meafures to be
