Inclination of their Orbits. By Thomas Bugge, F. R. S.

I. The heliocentric longitude and annual motion of Venus s nodes . 
T HE following agronomical obfervations were made at 
the Royal Obfervatory at Copenhagen with a fix-feet 
tranfit inftrument, and with a mural quadrant of fix-feet 
radius. It would be too tedious to enumerate all the original 
obfervations, which either are already printed, in the firft 
volume of my Agronomical Obfervations, or will very foon 
be publiflied in the fecond volume. 'I only fliall fet down tne 
obferved geocentric longitudes and latitudes, corrected for aber 
ration and nutation, and compared with the tables of Dr. 
Halley and of M. de la Lande.
