Example. SuppofeAfthe mean Anomaly from the 
Perihelion to be 1 20°. 00'. 00", to which it is rc- 
-quired to find the Anomalia Eccentri. 
Here, fince the mean Anomaly M is not many times 
more than the limiting Angie (which in 
this Orbit is about 74 Degrees) recourfe mull be had 
to the general Rule in the Propofition.

The Number N then, which is J—m will be 
y nR 
:= i, 0104195'; which found gives 
3 --— ‘ j 
n/ -+V-+ — = 1,0389090 5 and alfo 
==—0,4477126. Wherefore the 
Sum of both (under their proper Signs) viz. 
0,7911964 will be the Sine whofe Arch 36^,24197 
is the Angle A-, the Multiple whereof n't A 
— 1 29°, 297703, will be the Angle to be firft affirmed 
for the Anomalia Eccentri. 
For a further Correction ; this Angle, now called 
By whofe Sine is fuppofe /, and its Cofine z, gives, 
by a known Rule,' .#4. t z =1,1304 for x the Pla- 
net’s Diftance from the Sun 5 and by another known 
Rule b— — j< = i2o 0 ,i6768 for ju the mean Ano- 
maly to the Anomalia Eccentri B. Wherefore the 
corre& Angle b=b+ tx m—p will be i29°,i4846 
=129°. 08'. 74", 7, erring, as will appear from a fur- 
ther Correction, about 7% of a Second.
