Abstract: The theory of the characteristics of the second order differential neighborhood of conjugate　surfaces has been studied by many investigators. In this article the concept of curvature derivature tensor which describes the characteristics of the third order differential neighborhood of a surface is introduced. The relationship between the curvature derivative tensors of conjugate surfaces is derived for general case of relative motion. The gradient vectors of S21 and of n1·q21 are given.
