* Mean with the number for hydrogen actually observed. 
t Mean with the number (r44 as the coefficient of hydrogen. These last results are most to be depended 
upon, as the rate of the hydrogen alone is often raised by a slight impurity, of which the effect would become 
much less sensible in the mixtures containing that gas.
