The log; of 57-2957.795 is 1.758 1226 



The log. fine of 9° io'.99io6 is 9.2030095? 



Thefumis 10.961 132 j 



The log. of rad. is 10.0000000 



The difference 0.9611323 



is the log. of 9° 8'.6349999, the number of 

 degrees and minutes contained ip an angle 

 fubtended by an arc equal to the fine of 

 9° io'.99io6. The angle A therefore is 

 9° 8'. 6349999 ; the excefs therefore of the 

 angle BCD above the angle A is 2'.356o6.r 

 Again, as the fine of 9° 10.99106 is to the. 

 tangent of 8° 2'. 293 54, fo is the angle 

 2. 3 5606 to the angle DCQ* 



The log. of 2'. 3 5606 is 0.3721863. 



The log. tang, of 8° 2'. 293 54 is 9.1498998 



The fum is 9.522086 i
