Boys calorimeter

A recent (1911) type of gas calorimeter devised by C. V. Boys (Proc. R.S., 1906; A. 77, p. 122). The heated products of combustion from the burner B impinge on a metal box H, through which water is circulating, and then pass downwards and outwards through a spiral cooler which reduces them practically to the atmospheric temperature. A steady stream of water enters the apparatus by the inflow thermometer O.
