A DISCOVRSE
Presented to the Most Serene Don Cosimo II.
Great Duke of TUSCANY:
CONCERNING
The Natation of BODIES Upon, or Submersion
In, the WATER.
Onsidering (Most Serene Prince) that the publishing this present Treatise, of so different an Argument from that which many expect, and which according to the intentions I proposed in my * Astronomicall His Nuncio Siderio. Adviso, I should before this time have put forth, might peradventure make some thinke, either that I had wholly relinquished my farther imployment about the new Celestiall Observations, or that, at least, I handled them very remissely; I have judged fit to render an account, aswell of my deferring that, as of my writing, and publishing this treatise.
