fine of 9° 10’.99106. The angle A there- 
fore is 9° 8°.6349999; the excefs there- 
fore of the angle BCD above the angle A 
is 2’.35606. Again, as the fine of 9° 
10’.99106 is to the tangent of 8° 27.293 54, 
fois the angle 2’.35606 to the angle DCG. 
The log. of 2’.35606 is 0.3721863 
The log. tang. of 8° 2°.29354 is 9.1498998 
The fum is~ 9.5220861 
The log. fine of 9° 10%.99106 is 9.2030097 
The difference 0.3190764 
is the log. of 2’.084857 the angle DCG ; 
the angle ACG the anomaly of the ex- 
centric is 50° 51’.093797, that is 50° 51° 
5.62782. 
Let SM, perpendicular to CG, meet 
- CG inM: Ie is evident, becaufe the fec- 
_ tor ACG is common to both the fectors 
_ ASG, ACB, that if the fector ASG be e- 
qual to the fector ACB, the triangle SCG 
_ will be equal to the fector BCG; and 
_ therefore the line SM will be equal to the 
__ arc BG: If the fector ASG be greater than 
the fector ACB, the triangle SCG will be | 
greater than the fector BCG ; and there-
