carbon dioxide vanished as an ordinary imparity, and the total impurity fell away to a very small amount indeed.

In the following Tables the following data are given:—

• Column A gives the number of the experiment.
• Column„ B gives„ the„ date on which it was performed.
• Column„ C gives„ the„ hydrogen volume as measured and corrected to 0° C + 760 millims.
• Column„ D gives„ the„ hydrogenoxygen volume as„ measured„ and corrected„ to 0° C„ + 760 millims.„
• Column„ H gives„ the„ hydrogen in residue.
• Column„ O gives„ the„ hydrogenoxygen in„ residue.„
• Column„ N gives„ the„ impurity, determined by potash and pyrogallol.
• Column„ R gives„ the„ ratio of combining volume of hydrogen to that of oxygen when the impurity was assumed to be equally distributed in both gases.
• Column„ S gives„ the„ ratio of combining volume of hydrogen to that of oxygen when the impurity was supposed to be all in the hydrogen.
• Column„ T gives„ the„ source of the hydrogen.
• Column„ W gives„ the„ source„ of the„ oxygen.
