Despite the slight lack of clearness, octahedra arc clearlyshown which are striated on the surface, the striations over-lapfting each oiher like shingles on a house, the same structure,as Stead observed in his sample of steel, containing 4 per cent of silicon. The structure of silicon does not appear to beaffected by any temperature below its freezing jioint, as thegrains and crystals have the same appearance when quenchedat a bright red heat as when the cooling occupies 24 hours. This may explain why the structure of steels containing 4per cent of silicon is unaffected by heating to 1,10
