my Observations- I need not fay with what exa#nefs 
Dr. Found, and his Nephew Mr. Bradley did, myfel* 
being prefent, in the laft Oppofition of the Sun and 
Mays , this way demonftrate the extream minlitenefs of 
the Sun’s Parallax, and that it was not more than 12', 
nor lefs than 9", upon many repeated Trials, it having 
been foon after the time laid before the Society. But 
being mindful that in October next, Mars would be 
again in Oppofition to the Sun, about the tenth degree 
of Taurus , but would not come very near any fixt Star 
that has a place in Mr. Flamfteed* s Catalogue; I was 
folicitous to fee if there were any Telefccpick Stars to

noted the moment (lie pafs’d over the Center of my 
Glafs, or rather the common interfe&ion of the four 
crofs Hairs; and in half an Hours time I noted eight 
very confpicucus Stars, four of which being within rhe 
compafs of one Degree, fell very nearly in the /aid way 
of Mars, and from the intervals of Time I then ob- 
ferved, with their difference of Declination from Venus, 
I determined their Right Afcenfions and Declinations, 
as well as her Place from my Tables, ( which by 
Obfervation I found at this time needed no corre&ion) 
would allow me; they all falling between the ninth 
and tenth degree of Taurus, with very little Latitude. 
But what confirm’d me that all was right was, that on 
Tuefday laft Mar ch 2 1 . Mercury appearing very fair, and 
newly paft his greateft Elongation , I found by Sen ex's 
Zodiack that he was nearly in the fame parallel that 
Venus had before defciibed ; and though the brightness 
of the Crepufculum effaced the fmaller Stars, yet in a
