DR. A. SOOTT ON THE COMPOSITION OF WATER BY VOLmiE. 
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 2 T ^“6 
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.
