Excerpt from An Attempt to Establish, Vol. 1 of 2: The First Principles of Chemistry I have been in the habit, ever since the atomic numbers given in the present work were determined, to calculate the experiments of other chemists by substituting for the data which they employed, the more correct data which I myself possessed, and I have frequently found that the experiments, when so calculated, came much nearer the truth than the experimenters themselves were aware of. This was remarkably the case with respect to Mr. Fara day's experiments to determine the constituents of the chlorides of carbon, for a knowledge Of which we are indebted to that very ingenious and accurate chemist. The imperfect data which he employed has given his experiments the appearance of greater inaccuracy than the truth: for when the specific gravities and atomic numbers given in the following pages are substituted for those which he used, his experiments almost coincide.
