148 FSSAYS anp OBSERVATIONS — 
The log. fine of the angle BCD 
is’ iy" 8.7874623 
eT 
The difference —1,0931515 
is the log. of 641239228; the angle DCG, 
therefore, is 0.1239228; therefore the 
angle ACG, the anomaly of the excentric, 
is 41° 2942566553. | 
EXAMPLE Iv. 
AGAIN, in the fame orbit, fuppofing the 
mean anomaly to be 100° degrees, it is 
required to find the anomaly of the ex- 
centric. 
The log. tang. of 50°, half the 
angle ACB is TO. 0761865 
The difference of the logs. of 
AS, SP is . 0.0806086 
t 3 
The difference 9-9.55779 
is the log. tang. of 44° 42 -4982192, half 
the difference of the angles CSB, CBS ; 
therefore the angle CSB, that is, the an- 
gle ACD, is 94° 42". ie and the 
angle
