Parapets

en forme de crémail lere, Fr. Parapets which are so constructed within, in the form of a saw, that one of the faces of the redans, or teeth, is perpendicular and the other parallel to the capital. The chevalier Clariac, in his Ingénieur de Campagne, has given a particular account of these parapets. But the merit of having invented them does not entirely rest with him, since the Marquis de la Fond, director of the fortified places upon the coast of French Flanders, and M. de Verville, chief engineer at Rocroi, have likewise mentioned them.
