PEOFESSOE B. C. BEODIE ON THE OXIDATION AND 
from the peroxide of hydrogen ; and the denominator the difference of the number of 
atoms of oxygen contained in the peroxide of hydrogen, and the number of atoms of 
oxygen contained in the chromic acid employed in the experiment. 
Also if be the ratio of the total amount of oxygen evolved from the solution, to 
that evolved from the chromic acid. 
ns + n^s^—p + p^ T , 
_ 
The proportion of the oxygen evolved to the whole oxygen taken in the experiment 
The annexed Table contains the numerical results of the experiments, and the calcu- 
lated values of r, x, and y.
