With this Difference, consult the 3d Table: i.e. with 112, (omitting the .1 as too minute) on the remaining Decimals above 23.2, viz. on 05, as on 5, or ⁵⁄₁₀; and the Answer is 56 Feet: which Number being subtracted from 8379.7, the Remainder 8323.7, is the Height in Feet of the Barometer in the Car, at the Standard-Heat. Repeat the last Process for the Barometer on the Ground. Now 29.8, by the 2d Table, corresponds to 1856.0; and there being no Parts or Decimals more minute than a Tenth, viz. .8, there is no Occasion for the 3d Table. Subtract the Barometer in the Car, from the same when on the Ground; and, by the 2d Table, upper Barom. 23.25, corresp. to 8323.7, and the lower Barom. 29.8, to 1856.0: the Remainder is the Height in Feet —————— of the Barometer in the Car viz. 6467.7, with the Standard-Heat. _End of the second Stage._ 425. Detached Therm. above, at 65° Detached Therm. when below, at 65 ——— Whole Heat 130 Half Heat 65.(00 adding Cyphers) Standard-Heat 31.24 ————— which deduct, and there remains 33.76 Degrees more than the Standard-Heat, for each Barometer. Then for the Expansion of Air, with such Heat more than the Standard, consult the 4th Table: viz. _with_ 33°.76 _on_ Inches 6467.7, the Height of the Barometer in the Car with the Standard-Heat, thus: 426. _First_, _with_ 33°, _on_ 6467.7 _on_ 6000 as 6000 = 481.1, decimated 481.1 400 as 4000 = 320.7 32.07 60 as 6000 = 481.1 4.811 7 as 7000 = 561.3 .5613 .07 as 7000 = 561.3 .05613 ————————— Expansion = 518.59843 427. _Second_, _with_ .76 _on_ 6467.7: _on_, as before, 6000 = 1108. decim. 11.08 4000 = 738.7 .7387 6000 = 1108. .1108 7000 = 1292.7 .012927 7000 = 1292.7 .0012927 —————————— Expansion = 11.9437197 Add the former 518.59843 ———————————— Total Expansion = 530.5|542197 viz.
