D E G F is an horizontall line where ye hole G was.  It was 13 foot from D to C where ye surface of ye water was in ye reservatory there was measured 14 pints in 3 vessels, and it was agreed to be poured so that ye water might remain always at one marque B made at ye side of ye reservoatory at ye hieght C, and when in pouring the water was depressed a Line, it was poured swifter till it might pass a mark near as much the hole G was stopped with ye finger, and a pendulum that beat seconds was put into motion; be wch held ye hole stopped began to open it at G beginning at ye second and counted seconds following saying 0, 1, 2, 3, &c that wch poured ye water took held that when ye began to count ye water as precisely at ye height of ye mark and they ended pouring 14 pints between 0, and ye 60th second.  I made this experiment another way to avoid ye doubt of ye inequality of ye water wch was poured; there was put 7 pints into ye reservatory from a mark as H to another as L in equall distance from ye point B, ye hole was stopped with ones finger till ye seconds began to be counted to be at ye point L.

  It is easy to judge that during that running there would go out sensibly as much water as remained always at ye mean height B of 13 feet, because if it went swifter being M L it went also slower being in H in ye same proportion.

  Te experiments wch I made at great hieghts as 35 feet would give about 1/17 or 1/18th less than according to a a
subduple proportion at 13 feet to their heights; and those wch I made at ye  height of 6 or 7 feet would give something more, wch proceeds from ye greater or lesser rubbing against ye hole of 3 lines and of ye greater or lesser resistance of ye air but as these differences are inconsiderable, we may make calculations precisely  according to that rule of ye subduple proportion here as a table of ye quantities or water wch ye reservatorys of differ. weight did give unto 52 feet thrô an [[?(ajustair sole)]]

Transcription Notes:
mandc: "ajustage sole" is French for "sole adjustment." Looks like another instance of the translator meaning to come back latter when he has the acceptable English word. In another translation "adajustair" is translated as "ajutage" French for "nozzle."column
