Rh 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.

B  date on which it was performed.

C  hydrogen volume as measured and corrected to 0° C + 760 millims.

D

H  hydrogen in residue.

O

N  impurity, determined by potash and pyrogallol.

R  ratio of combining volume of hydrogen to that of oxygen when the impurity was assumed to be equally distributed in both gases.

S  ratio of combining volume of hydrogen to that of oxygen when the impurity was supposed to be all in the hydrogen.

T  source of the hydrogen.

W    oxygen.
