98 SPECIAL RESULTS IN THE URANOLO3ICAL PORTION 



coverer of Juno, has entered above 50000 stars in 27 sheets. 

 Bessel's great work of the observations of Zones of the 

 Heavens, comprising 75000 observations, and which extended, 

 in the years 1825 1833, from 15 to + 45 of declination, 

 has been continued by Argelander of Bonn, from 1841 

 to 1844, with a care deserving of the highest praise, and has 

 been carried by him to + 80 of declination. Prom Bessel's 

 Zones, between 15 and +15 of declination, Weisse of 

 Cracow, at the request of the Academy of St. Petersburg, 

 has reduced 31895 stars (of which 19738 are of the 9th 

 magnitude) to the year 1825. ( 188 ) Argelander' s "Review 

 of the Northern Heavens from + 45 to +80 of declina- 

 tion," contains 22000 well-determined places of stars. 



I think that I cannot refer to the great work of the star 

 maps of the Berlin Academy more worthily than by intro- 

 ducing, in Encke's own words, an extract on the subject 

 of this undertaking from his comprehensive discourse in 

 memory of Bessel. " With the completion of catalogues 

 is connected the hope that, by continued careful comparison 

 of the stars marked as fixed points with the aspect of the 

 heavens at the time of observation, we shall be enabled to 



Henderson. But the expense of printing these two catalogues was defrayed 

 by Her Majesty's Government, in consequence of a representation of their 

 importance to the purposes of practical Astronomy made by the British 

 Association to the late Sir Robert Peel. 



The catalogues of Lelande and Lacaille are distinct from the " British 

 Association Catalogue," not noticed in this part of the text of Cosmos, 

 but frequently referred to in the course of the volume. The " British 

 Association Catalogue" was also prepared under the superintendence of 

 Mr. Francis Baily, but in its case the cost of printing, as well as that of 

 preparing for publication, was defrayed by the contributions of the members 

 of the British Association. ED.]
