BY THE ANEROID.
Take readings of the barometer and thermometer at both stations; find in the the heights corresponding to the barometric readings, and subtract them. Multiply the remainder by . T and t being the temperatures, the product will be the difference in altitude.

The following table is to be used when applying the modified formula of chapter II:
Rule.—Find in the table the logarithms of the barometer readings to hundredths of an inch. Subtract these logarithms and multiply the remainder by 60000. The product is the approximate difference in altitude between the two stations. To apply the corrections for temperature, add the temperatures of the two stations and subtract 60°. Increase the above approximate value by of itself for each degree of excess above 60°. If the sum of the temperature is less than 60° diminish the value by a like amount.
