For N- 3, the observation of zone 405 has been employed, although the right-ascensions 

 differ by 16 s - The error seems not improbable, and has been assumed. 



For N- 22, the scale reading has been assumed as 1049, instead of 1089, making the observed 

 apparent d +25 36 9&quot;.8 ; and for 1849, the mean d +25 35 25&quot;.8. 



For N- 45, there is evidently a mistake of one division (=3 ) in the observation, making the 

 declination observed by Bessel +24 13 21&quot;. 6. 



For N- 95, zone 278, the scale-reading has been assumed as 990, instead of 1010, making the 

 observed apparent d +22 9 8&quot;. 7, and for 1852 the mean d +22 2 30&quot;. 6. 



For N- 97, the d of zone 275 has been retained, and that of zone 278 rejected. 



The Argelander Zones, that copious fountain of accurate positions of stars which are to be 

 met with in no other catalogue, furnish forty-one places of southern starts ; the original observa 

 tions of which, together with their reductions, here follow :
