Water Spouting at Different Levels; Force of Impact
Line a-n pours far less than b-c; point a takes a greater impact than n
Drawn inverted in red chalk, the leaf studies water spouting from channels set at different levels. One note observes that the line a-n, though of the same thickness as the line b-c, pours out far less water. A second, labelling a reservoir (bottino) with points n and a, states that a receives a greater impact than n.

Line a n pours much less water than b c
Comparing two spouts, the note holds that the line a n, being of equal thickness with the line b c, will nonetheless discharge far less water.
Point a receives a greater impact than n
A pouring vessel drains toward a reservoir (bottino) marked n and a; the note concludes that a receives a greater impact from the falling water than n does.
