The most extensive as well as the most delicate experiments ever undertaken, are those of Arago and Dulong, which were made at the expense of the French Government; these experiments range from 1 atmosphere up to 24, and the following formula has been given by those eminent philosophers, which will represent the temperature for pressures from 4 to 60 atmospheres, without any sensible error. These formulae differ a little from those given by Pambour; he p = (-269704 +-0068031 05..

If v be the volume of any given weight of elastic fluid under any pressure, and at the temperature of 32 of Fahrenheit, the volume it will occupy under the same pressure and at the temperature t, of Fahrenheit, will be v' = v + v x-00202 (t-32) (1) Also, for the volume vf' and temperature t, we have has made some slight mistake in converting the French measures into English.
