On the congruences of lines generated by the instantaneous screwing axes connected with some surfaces

In this paper, the surfaces z and z in [2] have been considered as the base surface x. And they are referred to their lines of curvature. The congruences generated by the instantaneous screwing axes of the moving trihedrons, nıoving along the lines of curvatire on z and z, have been investigated. And some corresponds with [1] have been explained.
