Page 567 - Any attempt to express, even in a comparatively complicated chemical equation, the nature of the metamorphosis which a gunpowder of average composition may be considered to undergo, when exploded in a confined space, would therefore only be calculated to convey an erroneous impression as to the simplicity, or the definite nature, of the chemical results and their uniformity under different conditions, while it would, in reality, possess no important bearing upon an elucidation of the theory of explosion...
Page 452 - ... large mass of iron at 100° C., though the latter may impart more heat to the electrified body. Neither the mere reception of heat, however intense, by the electrified body, unless the latter have such small capacity as to be itself intensely heated, discharges the electricity if the source of heat be distant, nor is discharge effected when the electrified body and a neighbouring cold one are surrounded by air through which intense heat is passing ; but, for the discharge, it is necessary that...
