Therefore the time 6f the beginriing^ 6h. mtn. P.M. 
The fiift contaft will appear i%id, 55 m, from the Suns Ze- 
nith. And / am perfwaded , that this Calculus doth exhibite 
this Phi&nQmemn nearly, as it will appear unto us : And /qu - 
ftionnot, but that in and Vi^zx owi Meriiim it will beobferva- 
ble, if the Air hiider not. It is an Appearance that will rich- 
ly merit the accurateft of our Cbfervations. For the Moons 
mean Anomaly being about 7 Sign, 1 1 dtg, we may the better 
judge by the Obfervation , Whether the Equations of her or- 
^/>t' be Ofcillatory 5 crnot. Nor need we fcruple about the 
M^uatmof Natural days: I have fully demonfirated the iE- 
quations, fo that /am perfwaded^ noonehererafter will contro- 
vert them 5 and /fhall erelong, if God will, commit them to 
your and the publick cenfure. 
/fuppofe the beginning of this Eclipfemay, if the Air be fe- 
rf ne , appear at London ; but its Meridian being removed to 
the Eaft from ours y 5 or 6 minutes , and its Latitude being 
lefs, fo that the Altitude of thepo^^^. and conf^quently the 
Parallax of Longitude wil be greater, and of Latitude, lefs : 
it followS;that the Eclipfe willberetarded,and that only the be- 
ginning thereof , fcarce to Obfervation, will there ap- 
pear > but in xht North and the Wejlern^zns of England and 
Scotland, it will appear more fully : and in Ireland it will be vifible 
to the middle of the Eclipfe. 
For the well-obferving of this noble Appearance , /need not 
fuggeft the way of cafling the Species of the Sun through a 
good Telefcope of a competent length , on an extended pa- 
per, placed behind the Eye-glafs fo far, as that the faid Spe- 
cies may appear at leaft 6 inches over 5 then dividing kth his P^- 
r//>^^rj^ into 3^0 degrees, for the better obferving the Inclinati- 
cnoi Cuffs of each Fhafts 5 and his Diameter into digits, 
and their paai by Concentrick Circles , for meafuring the 
quantities of the obfcured parts. For the meafuring of time, the 
skilful Obferver willbe furniflit withgood ^adraras^ Clocks^ or 
jPendulums.
