The gross pressure—that is, the pressure inclusive of the at- mosphere—is given in the seventh column. (2) In the second column will be found the “ sensible heat of steam—that is, its temperature (by the ther- mometer) whilst it continues to be steam—i.e., in a gaseous state—and is in reality its “ gaseous heat at different pressures. (3) In the third column will be found the “ latent ” heat of steam—that is, the heat that steam is capable of emitting when ceasing to be gaseous it returns to the liquid state—and is in reality its “ liquescent ” heat at different pressures.
