To these may be added Dr. IIerschell*s catalogue of 

 double stars, printed in the Plulosophkal Transattions for 

 1732 and (783; MEs^\EVi'sncbaUc and clusters oF stars, pub- 

 Jishcd in the Connoissancc des Tanps for 1784; and Her- 

 schell's catalogue of the same kind, given in the P/iiluso- 

 p/u'cal y transactions for 1786. 



In 1792, Dr. Zach, of Gotha, annexed to his Tahidce 

 Motuum Solis a new catalogue of the principal fixed stars, 

 from his own observations, made in the years 1787, 1788, 

 1789, 1790. This catalogue contains the right ascensions 

 and declinations of 381 principal stars; adapted to the begin- 

 ning of the year 1 800. 



But all these catalogues yield, both in extent and value, to 

 that of the De Lalandes, whose diligence, skill, and per- 

 severance, in this department of astronomical observation, do 

 them the highest honour. — Supplement to the Encyclopedia. 



Herschell's Construction of the Heavens, S^V. p. Q6, 



Tbis celebrated Astronomer has given a very sublime and 

 curious account of the Construction of' the Heavens, with his 

 discovery of some thousands of nebulte, or clouds of stars; 

 many of which are much larger collections of stars than all 

 those put together which are visible to our naked eyes, added 

 to those which form the galaxy, or milky zone which sur- 

 rounds us. He observes, that in the vicinity of those clus- 

 ters of stars there are proportionally fewer stars than in other 

 parts of the heavens; and hence he concludes that they have 

 attracted each other, on the supposition diat infinite space was 

 at first equally sprinkled with them. Mr. Herschell thinks 

 he has further shown, that the whole sidereal system is gra- 

 dually moving round some centre, which may be an opaque 

 mass of matter. See Philos. Trans, vol. Ixxix.

Professor Testa, of Rome, has read to the Academy of 

 Ivcligioii there, a memoir written by him, in whicli he proves, 

 in the most evident manner, that the ZodiacSy lately disco- 

 vered in Kgypt, have not that antiquity which some pretend 

 to give them, and, consequently, that they prove nottiing 

 against the chronology of Moses, lie asserts that the
