it From this fiiblirad the time of the EcUpfe after 
Nooii converted into degrees and minutes, the remain- 
der fliews you the Longitude of that Meridian on the 
earth, where it is then Noon when the Satellit is Eclipjed-^ 
which, I therefore call the Meridional Longitude of the 
Eelipfe, Biring this Meridional Longitude under the 
Meridian, and elevate the nearer Pole to theSiin as much 
as is his declination, keep the Globe in this pofition and 
ii 11^: be ui Confiequence of the Sun, draw a line on the 
Globe along the Eaftern /i9rii{<?f/, it pafles over ail thofe 
places where the Sun is fetting at that time, bat if Tbe 
in Antecedence oi the Sun, draw the. laid !me on the 
Globe by the Wefterne Edge of the Hori7^on, it paitei 
overall thofe places where the Sun is thenannng. 
Jupiter being in Confequence oi the Sun add i:he dif- 
ference of his and the Suns right afcent ions to the Meri- 
dional Longitude aforementioned, bring the degree of 
the jEquator anfwering their fumme under the Meri" 
dian, Raife the Pf?/^ next 5^at/^?>^r equal to his declina- 
tion, and detaining the Globe in this polition, draw a 
Ime again by the E^//^r« the fpace intercepted 
betwixt this and the line of the Suns fettings before de- 
Icribed on the Globe, Comprehends ail thole places on 
the earth from Sun fetting till is fet. 
But if ip v^^x^'m Antecedence of the Sun, SobftraA the 
difference of his and the Suns right Afcentions from 
the Meridional Longitude, fet the degree of the /Equa^ 
tor aniwering the remainder under the Meridian, and 
elevate the Pole ncKt Jupiter equal to his declination. 
Keeping the Globe in this pofition draw a line by the 
Wejiern Edg of t\xQ Horizon, the fpace included betwixt 
this, and the line or the Suns rifings contains all thole 
places, on the Earth where this i'^-////^ is vifible betwixt
