The authors consists in heating the nitrocellulose in vacuo^at a perature (140> C.), and measuring continu- y means of a mercury manometer, the pressure by the evolved gases, the latter being maintained taut volume. The rate at which the pressure •s is a measure of the rate of decomposition of. 65mm
