We may take, for an example of the utility of this mode of 
correction, the occultation computed in the Astronomical Col- 
lections, No. III. 
The elements of the calculation are, the true latitude of Paris 
48° 50’ 14”, for which the correction is 11’ 8”, giving the Geo- 
centric Latitude 48° 39’ 6”. 
The moon’s horary angles are 
3° 6™ 8°, and 4" 4™ 27° east, and her declinations 51’ 19” and 
1° 6’ 6” N.: the reduced parallax P. L. 5098 and 5096.
