Wheel-less bellows filling vessel b c with air
A siphon device in which air escaping from a reservoir mixes into the descending water
Leonardo describes an instrument without wheels that fills the vessel b c with air, charged by a plunger r S that travels four fingers up and down, matching the length of the tooth i. As the plunger descends, the vents o p open and the air of the largest reservoir passes down one branch of a siphon together with the falling water. He reasons that the escaping air equals the water in quantity and velocity, first condensing at the top of the conduit, and concludes that in truth the air mixes into the descending water in small particles. Further untranscribed lines run across the top of the sheet.

Wheel-less instrument filling the vessel b c with air
An instrument without wheels fills the vessel b c with air. Point a sustains the air until the vessel is full; the vessel is then closed above at n m and opened at o p, and on opening o p a vent opens at e to admit air. The air-vessel r S moves four fingers up and down, matching the length of the tooth i.
Escaping air mixing into the descending water
When the plunger r S descends, the lower vents of the greatest reservoir open and its air runs down one branch of the siphon with the falling water. The escaping air equals the water in quantity and velocity; it first condenses at the top of the conduit, then descends united with the water, in truth mixing into it in small particles.
Curved tube a b carrying air-laden water
In the curved tube, a b is the water that descends, into which the air is mixed in small particles.
