1what birds, what balls, and what other pretty things are here?

SIMP. Theſe are balls which come from the concave of the

Moon.

SAGR. And what is this?

SIMP. This is a kind of Shell-fiſh, which here at Venice they

call buovoli; and this alſo came from the Moons concave.

SIMP. And this is that calculation, which I mentioned, of this

Journey in a natural day, in an hour, in a firſt minute, and in a

ſecond, which a point of the Earth would make placed under the

Equinoctial, and alſo in the parallel of 48 gr. And then followeth

this, which I doubted I had committed ſome miſtake in reciting,

therefore let us read it. His poſitis, neceſſe est, terra circulariter

mota, omnia ex aëre eidem, &c. Quod ſi haſce pilas æquales

nemus pondere, magnitudine, gravitate, & in concavo Sphæræ

naris poſitas libero deſcenſui permittamus, ſi motum deorſum

mus celeritate motui circum, (quod tamen ſecus eſt, cum pila A,

&c.) elabentur minimum (ut multum cedamus adverſariis) dies

Theſe things being ſuppoſed, it is neceſſary, the Earth being

cularly moved, that all things from the air to the ſame, &c. So

that if we ſuppoſe theſe balls to be equal in magnitude and

vity, and being placed in the concave of the Lunar Sphere, we

permit them a free deſcent, and if we make the motion

wards equal in velocity to the motion about, (which nevertheleſs

is otherwiſe, if the ball A, &c.) they ſhall be falling at leaſt (that

we may grant much to our adverſaries) ſix dayes; in which time

they ſhall be turned ſix times about the Earth, &c.

SALV. You have but too faithfully cited the argument of this

perſon. From hence you may collect Simplicius, with what

tion they ought to proceed, who would give themſelves up to

lieve others in thoſe things, which perhaps they do not believe

themſelves. For me thinks it a thing impoſſible, but that this

thor was adviſed, that he did deſign to himſelf a circle, whoſe

meter (which amongſt Mathematicians, is leſſe than one third part

of the circumference) is above 72 times bigger than it ſelf: an

errour that affirmeth that to be conſiderably more than 200,

which is leſſe than one.

SAGR. It may be, that theſe Mathematical proportions, which

are true in abſtract, being once applied in concrete to Phyſical and

Elementary circles, do not ſo exactly agree: And yet, I think,

that the Cooper, to find the ſemidiameter of the bottom, which he

is to fit to the Cask, doth make uſe of the rule of Mathematicians

in abſtract, although ſuch bottomes be things meerly material,
