is the log. of 5° 16’.600752, the number 
of degrees and minutes contained in the 
angle A; the excefs therefore of the an- 
gle BCD above the angle A is 0’.9010288, 
Again, as the fine of the angle BCD is to 
the tangent of the angle DCF, fo is 
079010288 to the angle DCG. 
. The log. of 079010288 is —1.9547387 
The log. tang. of the angle 
DCF is. 8.8440431 
The fum is 8.797818 
The log. fine of the angle | 
BOD is 8.9642381 
The difference —1.8345437 
is the log of 06831934; the angle DCG 
therefore is 0+68319343; therefore the 
angle ACG the anomaly of the excentric 
is 94° 437.1814126, 
Tue three laft examples are taken from 
Dr Keil’s aftronomical Lectures, Lecture 
23- and the numbers agree very nearly 
with his. |
