Excerpt from Pray's Steam Tables and Engine Constants: For Facilitating All Calculations Upon Indicator Diagrams, or Various Problems Connected With the Operation of the Steam Engine, From Reliable Data and With Precision

The density of steam is correctly given in this volume, taking Prof. Rankine as reliable, and no one today has the abstract facts on that property of saturated steam to any greater certainty than he had, and up to date no one has given facts to consider in place of his reasoning, nor with any approximate basis beyond their own conception of what might be. The tables here given will, to some extent, increase the amount of steam used in any place, but it is correct from present knowledge, and with Regnault's observations and results, and Rankine's verifications of those same results, we must be put in possession of far more accurate data, than the suppositions of theorists, before we attempt to alter the Rankine basis, for saturated steam, for the simple, but indisputable reason that his basis was entirely from Regnault's actual experiments, in using steam, under practically the same conditions that steam engines use it in practical work, while the density is assumed to a great degree in any case, the basis herein adopted is assumed only so far as the higher pressures are given, it is almost positively known for some of the lower range.
