Andreefs values of the pressure t exceed ours but little—at 32°*6, on an average, about one atmosphere. This mayarise from the air-content of the carbonic acid being inAndreefs experiments somewhat less than in ours. Thevalues of 2) calculated by Clausiuss formula, however, are notinconsiderably higher than those observed by us: the differ-ences increase with the density, and reach the value of 10-12atmospheres.
