mumber of degrees and minutes in an 
angle fubtended by an arc equal to the 
fine of 5’..803186. 
The log. of 57°.2957795 is —_ 1.7581226 
The a fine of 5° See Is 7.1633313 
The fum is 8.921453y 
The log. of radius is 10,0000900 
The difference 249214539 
_ The difference 
is the log. of 5’ .0073 162, he number of 
minutes contained in the angle A; the 
excefs therefore of the angle BCD, above 
‘the angle A, is 0 .0930024. Again, as the 
fine of the angle BCD is to the tangent 
of the angle DCF, fo is 0,0930034 to the 
angle DCG, 
The log. of 0’.0930024 is —2.9684941
