(12) Konigsberg 1820. These values of A 8 $ apply to the results of Dollen’s reduction of 
Bessel’s observations. ( Recueil de Mem. des Astronomes de VObs. Cent, de Russie, Vol. 2, pp. 203- 
232.) 
(13) Cape 1833. The A85 for Henderson’s Cape declinations follows from a special discussion 
published in Nos. 540-541 of the Astronomical Journal, Vol. XXIII, p. 123; Catalogue of 
627 Principal Standard Stars, pp. 67-71. An important part of the correction is supposed to 
originate in an abruptly varying error of graduation. The correction is most effectively given for 
each degree, as in the following table.
