From b to the side toward the grinding surface thedefectiveness grows less {c)\ but immediately increases, when thatside is reached, to proportions which it maintains until the oppositeside corresponding to c is attained (at d), where it again decreases,widening again, however, at ^, the point corresponding to b.
