Sir Jfaac Newton found the Area of a tranfverie SeCtion of the Vein at the Diftance of about a Dia¬ meter from the Hole, to be lels than the Area of the Hole in the laid Proportion. And in the Determi¬ nation of this Motion he liippoies the Hole to be contracted in that Proportion, and the Velocity, with which the Water flows through it, to be equal to the Velocity in the con¬ tracted Part of the Vein, that is, equal to the Velocity which a heavy body will acquire in falling in vacuo \ % J' j through G I, or yrrz In order to know, whether the Velocities of Water flowing through circular Holes of different Diame¬ ters at the fame perpendicular Di¬ ftance
