“ We regret to announce that Sir William Galloway, the mining engineer, whose pioneer researches in the action of coal dust in colliery explosions were among those which led to the saving of many lives, died at Cardiff on Wednesday night. ”

“ He conducted a series of experiments with different kinds of explosives fired into mixtures of gas, air, and coal dust for the Royal Commission on Accidents in Mines. He also determined the relation between height of firedamp cap and proportion of firedamp in the air of mines, and invented the guides for sinking pits. ”
