A CATALOGUE OF STANDARD STARS. 541 
volumes for 1858 and 1859 did not come to hand till after the completion of the com- 
putations. The corrections for equinox here used were 
Gr. C. 1850 + 0*.017, 
Gr. Obs. 1854 — 1859 + 0*.027, 
Paris + 0.056. 
The mean of the corrected deviations of these four catalogues from the computed 
places, gives the correction a? for the mean £^ of the dates. This was reduced to 1855 
by the formula x = 2° a PS , the correction æ was applied to the assumed places for 
1855 (the Greenwich results 1855), and the right-ascensions of Table VI.formed. The 
annual variation given here is that which results from the combination of the mean 
annual variation derived from these right-ascensions compared with Bessel’s Bradley, 
with the secular variation of the last column ; which had been computed. 
For the 47 stars given by Wolfers the positions are derived from the materials of 
his work, and are here computed for convenience' sake.
