Abstract
A new form of waterβflow gas calorimeter is described in which gas volumes are read with a soapβfilm meter, and water volumes on a burete. The calorimeter is a silvered and evacuated resistanceβglass vessel. A new type of pump is used to supply air to the burner. The gross calorific value of a gas can be obtained in to minutes if the rates of flow of air, gas and water arc set correctly. The calorimeter was designed to give results correct to the nearest I3.Th.U. but an accuracy greater than this may he possible.

A new flow mixing calorimeter designed to measure the excess molar enthalpy of gaseous mixtures for which this quantity is positive is reported. The calorimeter is designed for use at pressures close to atmospheric and at temperatures up 473 K. Unlike the previously described flow mixing calorimeter
