thus found is to be taken for the next: procefs,becaufe, i in thefe calculations, we find 
her parallax in altitude, latitude and longitude from the fun, to prevent feparate- 
proceffes for his parallaxes. When we are making thefe calculations in occultations 
of the fixed ftars by the moon, her true horizontal parallax will neceflarily be ufed,. 
becaufe the fixed fars have no difcoverable parallax.
