44$ Mr. South on the discordances between the 
f That 28 observations made at the Observatory in 
Blackman-street, found the observed right as- seconds, 
cension, to exceed the computed, - 0.652 
- And that by 28 corresponding observations at the 
Royal Observatory of Paris, the observed right 
ascension, was determined to be greater than 
( thecomputed, ------ 0.558 
"That by 15 observations in Blackman-street, the 
observed right ascension, was found greater 
1 than the computed, by 0.693 
And that 15 correspondent observations made at 
the Observatory of Dublin, the observed right- 
ascension, exceeded the computed, by - - 0.686 
Seeing therefore that results not materially differing from 
the Blackman-street determinations, are derived from the 
Greenwich, the Paris, and the Dublin observations, it is rea- 
sonable to conclude, that the discordances between the ob- 
served and computed right ascensions of the sun, as found 
b)> the Blackman-street observations, did not arise from any 
peculiarity in the eye, or judgement of the individual em- 
ployed, in obtaining them. 
We have however hinted in a former part of this memoir, 
that the differences as determined in Blackman-street, were 
not constant ; and by reference to the preceding tables, dis- 
cordances amongst them, to an amount far greater than can 
be attributed to erroneous observation, will readily be de- 
tected ; hence, an investigation into their nature, becomes de- 
sirable ; this, however, would lead us into an inquiry beyond 
the purport of the present communication ; which, besides a
