Rule.— -Multiply the number in the table opposite to the mean of the temperatures of the
two places in degrees of Fahrenheit, by the difference of the barometric heights, and divide by
their sum. Ttie quotient is the height in feet.
Example.— On the 20th October 1850, the barometer stood at 29*85 in the Mhar river
near the sea, the thermometer indicating 83*5; and at the Monastery Mahahleshwur it fell to 25*79*
and the thermometer to 68*5. Required the height. Here the mean temperature is 76°, opposite
to which in the table is found 57541, which being multiplied by 4*06, the difference, and
divided by 55*64, the sum of the barometric heights, gives 4198 feet, the height required.
Table of Heights found by the Aneroid.
Kenesore above the level of the sea feet 665
Monastery Mahabuleshwar feet 4198
Mount Charlotte above Monastery feet 324
Mount Charlotte above the level of the sea .feet 4524
Tai Ghaut... feet 1362
Height of Ghaut above Poona * feet 1216
Poona above the level of the sea feet 2025
These heights, as far as I have been able to ascertain, coincide very nearly with the heights
ascertained by other means. Indeed no single observation of the barometer at one of the places
could be expected to give it more accurately.
Leslie’s rule is very convenient, and sufficiently accurate ; but the correction for the tem
perature of the air at the two places is often neglected in practice,—and even in some
scientific Works the fact of a correction being required is not mentioned. But this correction
cannot be omitted, because in the case of Mahableshwur it amounts to upwards of 400 feet, and
in the case of Poona to about 180 feet. The results, however, are always too small, because in his
investigation, he was only anxious to obtain an approximation, and neglected systematically all but
round numbers, and all the omissions tended to reduce the apparent height. Near the equator
the diminution of the force of gravity is another source of error, which still more diminishes the
height deduced from the usual formula. I have therefore used, in the f irmation of the table
given above, the number 52416, deduced from Poisson’s formula, in preference to 52000 used by
Leslie. Besides, the thermometers in general use being graduated according to Fahrenheit's
