Theory, as I find them publifh’d in the Ingenious Mr 
Whiftori s Aftronomieal Lectures, with the Radix's of 
the Mean Motions, corrected according to their firft Au- 
thors later Obfervations, which are the fame with thofe 
aftum’d in Sir Ifaac Newtons Theory, 
By comparing thefe two Calculations we may ob- 
ferve, that tho’ moft of the additional Equations in Sir 
Ifaac Newton's Theory be very fmall in this Situation of 
the Moon, yet they all confpire fo as to make its Place 
confiderably more agreeable to Obfervation, than thofe 
of Horroxs Syftem. 
The Obfervation was made at Strcatham , about fix 
Miles near direft South of London, with a very good 
Eight foot Telefcope. To correft the Clock, (for want 
of an Inftrument,) I carried with me next Day two 
Watches, that were before adjufted to the Clock, and 
compar’d them with Mr. Fla/njieed’s at the Royal Ob- 
fervatoiy, having firft noted its Error by an Obferva 
tion of the Sun’s Tranfit of the Meridian his Afliftant 
communicated to me : Upon my return, I found my 
Watches ftill to agree together, and to my Clock, which 
prov’d them to have gone true, and gave me the exaft 
Error of my Clock, and the true time at Obferva 
tion. 
Mr* Flam feed has fince been plealed to acquaint me, 
that by his Obfervation of the Meridional Tranfit ol 
the Lyons Heart during the Eclipfe, his Clock needed 
a yet further Correction of one Minute, which I have 
here accounted for.
