[Commentary:
The page is part of Harriot’s
introduction of compound diagrams of motion, a group of folios on which Harriot eventually succeeds in deriving, by means of such diagrams, a general expression for the time of flight of a projectile (Schemmel 2008, Section 8.2). ]
The problem of finding the time of flight of a projectile formulated
on the upper part of
f. 26
is adequately reformulated in terms of a compound diagram of motion.
The result is noted as an equation as well as a proportion.
