AT THE OBSERVATORY AT PARAMATTA.

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

Amongst the Culminations of the Moon and fixed Stars observed in Europe 
and hitherto published, I found but a small number corresponding with those 
observed at Paramatta. 
Mr. Francis Baily has deduced, from an Observation made on the 30th

of May, the Longitude of Paramatta 3 44.17 
Professor Nicolai found from the same Observation 3 49.00 
Mr. Claussen from an Observation made on the 23rd of March, 1823, 
at Greenwich and Paramatta (Star Regulus), found 4 15.00 
From an Observation made at Paramatta, 29th June 1826, and at Abo 
by Professor Argelander (Star a Arietis), I find 3 52.16
