^ AT THE OBSERVATORY AT PARAMATTA. 27 



however necessary to remark, that in the absence of corresponding observa- \ 

 tions, the longitudes rely upon the Lunar Tables, and can therefore be much 

 vitiated by small errors in the position of the Moon as well as of the Stars. 



Longitude of the Observatory at Paramatta, deduced from the Eclipses and 

 Occultations of fixed Stars, by Professor Wurm, of Stuttgard.

Amongst the Culminations of the Moon and fixed Stacg observed in Europe 

 and hitherto published, I found but a small number corresponding with those 

 observed at Paramatta. ^
