568 The value 2.00245 is for temperatures about 14° to 18° C. If, however, the values for the coefficients of expansion of oxygen and hydrogen be taken as $1⁄272.16$ and $1⁄273.13$ respectively, we have for the ratio at 0° C., 2.00285.

In conclusion, I have only to say that every measurement in all the experiments was made by me, and that all the solutions required were made up, and cleansings of the apparatus, &c., were carried out by my own hands, so that no ambiguity could arise without my being in the position to elucidate any possible error at any time.
