formed by Flamstead, was before mentioned a$. 

 one of the most complete ever derived from the 

 labours of an individual. To this succeeded the^ 

 observations and catalogues of I>e la Caille,. 

 Bradley, and Mayer, w^hich it is scarcely neces- 

 sary to say were highly valuable. After these, M^ 

 Bode, of Berlin,, published, in 1782, a veryexten- 

 sive and improved catalogue, which is greatly- 

 esteemed among astronomers. He was followed 

 by the celebrated Baron De Zach, of Gotha,. 

 Tvhose catalogues and tables, in many respects, 

 excelled all that had preceded them. Besides 

 these, the public has been favoured with interesting; 

 accounts of new stars, by Hersci-iel, Maskelyne,. 

 the elder Lalande, and many others. The num- 

 ber discovered by the powerful instruments of 

 Herschel, in particular, is ahPxOst incredibly great. 

 But the last, and the most complete series of ob- 

 servations ever made in this department af astro- 

 nomy, is that lately announced by Le Francais 

 Lalande, the nephew of the veteran in science^- 

 of the same name before mentioned, who, with 

 the assistance of his ingenious and enterprizing 

 wife, has determined the places of fifty thousand 

 stars, from the Pole to two or three degrees below 

 the Tropic of Capricorn/ 



We may also reckon among the great astrono- 

 mical improvements of the last age, the formation^ 

 of many Tables, exhibiting the places and motions- 

 of the heavenly bodies. Among these are the 

 Cometarial Tables o^Th. Halley, since enlarged 

 and corrected by many hands, and particularly by 

 a number of eminent French astronomers. To the 

 same list also belong Tables of the Siai and Mooiiy 

 bv Le Monier, and De la Hire; the Solar Tables
