| viz. | 7292.1 | from ditto in lower Barometer, |
| viz. | 3357.0 | and there remains the Height in Feet |
| ——— | of the upper Barometer at the Standard-Temperature | |
| viz. | 3935.1 | of 31.24. |
End of the second Stage.
Section, 404.
On which Number of Feet, viz. | 3935.1, | by the | |
| 4th Table, find the Height, with | 28°.71 | of Heat: | |
| With 28°. | on Feet 3935.1 = | 267.7 | and |
| With.71 | on the same = | 6.7 | |
——— | |||
Sum | 274.4 | : which | |
| Height, more than the Standard-Heat, being added to | 3935.1 | ||
| the Height, with the Standard, | ——— | ||
| gives the true Height, viz. | 4209.5. | ||
End of the third Stage.
