Sun’s observed and computed right ascensions, &c. 44,9 
brief description of an admirable instrument, was intended 
chiefly to show, “ that the discordances between the observed 
and computed Right Ascensions of the Sun, as determined at 
the Blackman-street Observatory, in the years 1821 and 1822, 
did not originate, in instrumental inaccuracy.” 
I hope however ere long to show, to the satisfaction of the 
Society, that the source of the discordances, must be sought 
for, in the imperfections of the Solar Tables.
