He records an experiment to test the movement of water at different levels in rivers and then sets out to prove that water pressure, and therefore velocity, increases as the depth increases. He tests this hypothesis in another laboratory experiment described on 11r. His approach is scientifically interesting for taking into account the complexity of forces that contribute to the flow of water. He
