Additional evidence of a Flat Earth can be found in the book
Zetetic Cosmogony: Or, conclusive evidence that the earth is not a revolving-rotating-globe, but a stationary plane circle by Thomas Winship. In this work Mr. Winship confirms for us several necessary attributes, such as the lines of latitude growing longer beyond the equator, the motion of the sun circling above the earth, the convexity of water, et cetera.
