A calorimeter has been designed for measuring the heat of mixing of liquid systems, which eliminates the need to correct for changes in the composition of the vapour phase on mixing. Improved accuracy has been obtained. It permits the measurements of thermic effects of the order of 0.005 joule, corresponding to temperature differences of 10 −4 of a degree. Heats of mixing have been measured for the system hexadecane‐hexane, the results of which are highly satisfactory.
