In a paper communicated by one of us, in April last, to the Royal Society, a calorimeter was described for determining the heat emitted by man, which, on being tested, was found to give very reliable results. At the same time a short history was added of the various instruments, used by physiologists to estimate the heat given out by man and animals; from that list was accidentally omitted the calorimeter of D’Arsonval. This calorimeter consists of two cylindrical concentric vessels, with an air space between them, and standing in an annular groove full of water, thus making an air-tight joint.
