$M$ of class $C^{infty}$ to its cotangent bundle $cT(M)$ were introduced in a recent paper, [4]. Vertical lifts of functions, vector fields, l-forms and tensor fields of type $(1, 1)$ or $(1, 2)$ were defined. The definitions of complete lifts were restricted to vector fields, tensor fields of type $(1, 1)$ and skew-symmetric tensor fields of type $(1, 2)$ . In each case, the complete lift of a tensor field has the same type as the original; however vertical lifts do not have this property. In S 2 of the present paper, we summarise the details of the relevant formulae. In the present paper we introduce another type of ” lift ” from $M$ to
