Abstract
28,745. Schruf, G. Dec. 31. Stone, artificial; cements.-In a stone or mortar consisting of sand or other filling-material, cement, tar, or similar bituminous materials, the proportion of tar &c. never exceeds 10 per cent. This ensures a material of great strength and impermeability to water, suitable for lining the walls of tunnels, and for ceilings and damp-proof courses in the walls of buildings.
