pared with it, we fhall find no greater Difference, 
than what may be luppofed to arife from the Uncer- 
tainty of the Obfervations themfelves ; it no where 
amounting to more than iLi. The Hypothefis there- 
fore feems, in this Star, to agree extremely well with 
the Obfervations here fet down; but as I had made 
above 300 of it; I took the Trouble of comparing 
each of them with the Hypothefis: and altho 5 it might 
have been expe&ed, that, in fo large a Number, 
fome great Errors would have occurred ; yet there 
are very few, viz. only eleven, that differ from 
the mean of thefe fo much as 2"; and not one that 
differs fo much as 3". This furprifing Agreement, 
therefore, in fo long a Scries of Obfervations, taken 
in all the various Seafons of the Year, as well as in 
the different Portions of the Moons Nodes, feems to 
be a fufficient Proof of the Truth, both o tthis Hypo- 
thefis, and alfo of that which I formerly advanced, 
relating to the Aberrations of Light; fmcc the Polar 
Diftance in this Star may differ, in certain Circum- 
ftances, almoft a Minute, viz. s 6 "±, if the Cor- 
rections refulting from both thefe Hypothefes are 
neglected ; whereas, when thofe Equations are 
rightly applied, the mean Place of the Star comes 
out the fame, as nearly, as can be reafonably ex- 
pected.
