1 They are one globe hauing the same Center or middle pointe, and the same surface or conuexe superficies, which will appeare by these reasons.

1 Common experience.  Take a lumpe of earth and any quantity of water, and let them both fall downe together vpon the earth from some high place, wee see that in the desc[e]t they doe not seuer, but keepe still together in on streight line, which could not bee, if the earth and water were two seuerall round bodies hauing seuerall centers.  As for example suppose them to bee two globes and let (_a_) bee the Center of the earth and (_b_) the center of the water; fr[o] (c) some high place aboue the earth hurle downe earth and water, I say the earth will part from the water in going downe and the earth will fall downe vpon (d) & the water vpon (e) but this is contrary to experience & ergo the supposition is false.

2 The shadow which in Eclipses is cast vpon the Moone by the earth and the water, is but one and not two, & therefore the body is so likewise.  This will appeare in the proofe of the next point, v. 2.

2 That both earth and water are one round body, not square, long, hollow, of any other figure.  This is proued by diuerse reasons.

1 By Eclipses; when the earth, stands iust betweene the Sunne and the Moone, then doth the shadow of the earth falling vpon the Moone darken it wholy or in part.  Now as is the fashion of the shadow, such is the figure of the body, whence it falls, but the shadow of the earth and water cast vpon the Moone is round, and also one, therefore they are round and also one body.

2 By the orderly and successiue appearing of the starres, as men trauile from North to South, or from South to North, by sea or land.  For as they goe by degrees, they discouer new starres, which they saw not before, and loose the sight of them they did, which could not bee if the earth were not round.  As for example, let (X.O.R.) the inward Circle bee the earth, (Q.S.P.) the outward, the Heauen:  they cannot see the starre (S) which dwell vpon the earth in (X) but if they goe Northward vnto (O) they may see it.  If they goe farther to (R) they may see the starre (P) but then they loose the sight of the starre (Q) which being at (X) and (O) they might haue seene.  Because, as it appeares in the figure, the earth riseth vp round betweene (R) and (X).

3 By the orderly and successiue rising of the Sunne and starres, and settinge of the same.  Which appeare not at the same time to all countryes, but vnto one after another.  As for example, let (F.C.B.) be the Circle of the earth, (D.E.A.) the Circle of the heauen from East to west, let (A) bee the Sunne or a starre.  When the Sunne (A) is vp, and shines vpon them that dwell in (B)
