60°, the anomaly of the excentric will be 
50°.85154, that is 50° 51.0924. 
In order to determine the difference be- 
tween SH and the arc BG according to 
this computation, 
The log. of 20589 is 4+ 3136353 
The log. fine of 50° 51’.0924 is 9.8895888 
The fum is 14.2032241 | 
The log. of rad. is 10.C000000 
’ The difference 4.2032241 
is the log. of SM. Again, as CA to SM, 
fo is 57°-2957795, &c. the number of
