When the moon is very near the ecliptic, as in 

 eclipfes, the following method will be nearly exact. 



1. Add the cofine of the altitude of the nonagefimal 

 degree to the logarithm of the horizontal parallax; the 

 fum (rejecting radius) is the logarithm of the parallax 

 of latitude nearly: add this parallax to the complement 

 of the altitude of the nonagefimal degree, and call the 

 fum the complement of the altitude of the nonagefimal 

 degree corrected. 



2. Add the cofecant of the complement of the altitude 

 of the nonagefimal degree, the fine of the complement 

 of the altitude of the nonagefimal degree corrected, and 

 logarithm of the parallax of latitude, nearly together;
