Denoting the height difference, station – Kāshgar, by Δhₐ and Δh_b according as method
(a) or (b) is employed the following results are arrived at. Δh is the mean of Δhₐ and Δh_b.

| Station | Date | Hour | Δhₐ | Δh_b | h = Δh + 4043 | Previously adopted height | Observed pressure | Pressure corresponding to height | Deduced correction |

* Observations starred have been weighted 4.

Mean correction to aneroid = −0·23 inch.

This correction has been applied to all the remaining observations and these have been
reduced by both the methods (a) and (b); the mean of the resulting values has been taken
for the final height.

The results are exhibited in the following table :—
