-STRONOMY is a fcicnce not only noble and exalted 

 in itfclf, but attended with fo many advantages that little 

 needs be faid in its favour. Its utility in navigation, by 

 which means that art has been brought to a ftate of very 

 great pcrfeftion, is alone fiifficient to fliow its importance, 

 and confcqucntly the benefits that muft arife to focit-ty by 

 encouraging and promoting it. Moft of the civilized coun- 

 tries in Eur()[K*, indeed, have lately paid confiderablc at- 

 tention to thi.A important object. And the great improve-^ 

 ment made in the conftruClion of telefcopes, and other 

 aftronomical infiruments, has produced difcoveries^ and an 

 accuracy in obfervalions of the celedial bodies, which other- 

 wife could not have been expefted. By the munificence 

 and liberal proiettion of our moll gracious fovereign, who 

 has always fliovvn himfelf a friend to fcience, thele im- 

 provements have becn^ carried to a very great extent in this 

 country : a:id it mull fill the breaft oi every patriotic Briton 

 with honclt pride, to reflcdl that there is fcarcely an ob- 

 fcrvatory in Kurnpe which is not furniflicd with teIefcopc3
