fatisfic j T our Lordfhip of the general Corrcfpondency 
between the Hypothecs and the ‘Phenomena, in the 
feveral Stars,* how ever different their Situations are, 
with refpeft to the Cardinal Points of the Equator. 
As I made more Obfervations of y c Draconi$ 
than of any other Star 5 and it being likewife very 
near the Zenith of Wanfted 5 I will begin with the 
Recital of fome of them. The Point upon the 
Limb, with which this Star was compared, was 
38°. 25' from the North Pole of the Equator, ac- 
cording to the Numbers of the Arc of my Seffor. 
The firft Column, in the following Table, fhews 
the Year and the Day of the Month, when the Obfer- 
vations were made} the next gives the Number of 
Seconds , that the Star was found to be South of 
38°. 25': the third contains the Alterations of the. 
Polar Diftance, which the mean Precefiion, at the 
rate of one Degree in 7 id- Years, would caufe in 
this Star, from the 27th Day of March 1727, to 
the Day on which the Obfervation was taken: the 
fourth fhews the Aberrations of Light: the fifth, 
the Equations arifing from the Yorementioned Hy- 
pothefis: and the fixth gives the mean Diftance of 
the Star from the Point with which it was compared, 
found, by collecting the feveral Numbers, according 
to their Signs, in the 3d, 4th, and 5th Columns, 
and applying them to the Obferved *Diftances con- 
tain’d in the Second. 
If the Obfervations had been perfectly cxaCt, and 
the feveral Equations of their due Quantity} then all 
the Numbers in the laft Column would have been 
equal 5 but fince they differ a little from one another ; 
if the meanoi All be taken, and and the Extremes are 
D compared
