* By an entirely different method Regnattlt has examined the expansion by heat of carbonic acid gas 
between 0° and 100° for pressures varying from 1 to 15-6 atmospheres. As his results form a consecutive 
series with those of Table YI. I subjoin them. It must be remembered that p represents here true pressures 
in atmospheres.
