Paper, 'On the influence of coal-dust in colliery explosions. Number 3' by W [William] Galloway Galloway continues with his experiments into the influence of coal dust in colliery explosions, this time using a larger apparatus than the one used in his earlier experiments. He relays details of colliery explosions that took place in Risca, Penygraig [Wales] and Seaham [Durham, England], and explains that 'for the purposes of the present paper I visited Risca Colliery on the 24th of October, and Seaham Colliery on the 24th of November, and I have had the rare opportunity of becoming thoroughly conversant with every circumstance connected with the Penygraig explosion, and with the events which immediately preceded and accompanied its occurrence.'
