The angle at the planet is found in the manner before menti- 
oned. The following table contains the heliocentric longitudes 
and latitudes to the moments of mean time in the foregoing 
table. The heliocentric place of the node is afcertained with 
a tolerable degree of accuracy ; hence the arc of the ecliptic
