nexion with his discovery of the influence of an admixture of 

 shale-dust in preventing explosions in collieries, a discovery which 

 has had a far-reaching effect in diminishing the dangers of coal- 

 mining, and has led to the compulsory treatment of passages in 

 mines with stone-dust, as a preventive of the spreading of explo- 

 sions. He took interest in the design of helmets, by means of 

 which rescue-parties might penetrate into poisonous atmospheres, 

 giving freely from his private funds to the research. He had been 

 President of the Mining Association of Great Britain, and of the 

 Institution of Mining Engineers, and was knighted in 1914. He 

 was elected a Fellow of our Society in 1891.

 founders, and the first President, of the Liverpool Greological

 the British Polar Expedition, and travelled much on his own 

 account, principally in the polar regions ; to geology his principal 

 contributions were his observation of the effects of ice-action in 

 those northern regions, and especially his recognition of, and obser- 

 vations on, the action of floating ice in abrasion and transport. 

 He was elected a Fellow of this Society in 1875.
